How to set active APN on ICS
Android 4: Under Mobile Network Settings I have Access Point Names menu, which lists 4 APNs, first one's got a radio button selected next to it.

I'm trying to select one of the other APNs - which takes me to edit mode for that APN, however there doesn't seem to be a way to select an active one (as in - put a radio button selected next to it).

Long tap and menu options don't provide that ability either.

问:
My OS and phone freeze and lag every time the blue "Show CPU Usage" bar appears. What is it?
Lately, I've been experiencing the very unpleasant phenomenon of my almost new S3 completely locking up and stopping responding to input. It's like a very serious lag that has to either be waited out, or the phone needs to be rebooted by force. Whenever this happens, my underlying apps still work, albeit laggily because CPU spikes through the roof but I cannot interact with my phone - it doesn't react to my touches. If I try forcing it, it only wastes more CPU power on, well, nothing. I am 100% certain that my touch screen is ok - it works as intended in all other cases. When it locks up (and it does so for 10 minutes at a time if not more - I hadn't had the patience to wait longer) I can pull out the battery and reboot that way. The curious thing is, however, that once put back in, the battery will have around 10% less charge in it, every time, unless I pull it out in the first 30 seconds of the lag. It's like its CPU spikes so high through the roof it uses up 10% of my battery in next to no time on operations I cannot identify.

I have activated Show CPU Usage as I suspected the CPU might be overtaxed, and have come to the definitive conclusion that every time these lockups happen, a huge blue bar appears in the Show CPU Usage graph. As soon as it goes away, everything is peachy again.

I have looked it up, but could find no answer more detailed than this: https://stackoverflow.com/questions/10829546/how-to-read-the-stock-cpu-usage-data

My question is - what is the blue bar precisely, and how can I find out what's causing it. Mind you, whenever this happens and my CPU is past 100%, none of the apps listed under the bar actually have a usage higher than 2%. This is not app based, this is something in the OS or the underlying hardware that's malfunctioning - my initial guess was that the internal memory got corrupt somehow and is taking too long to read/write, but I'm just speculating.

问:
Wi-fi disabled during lock still partly active? Or do I mis-interpret the battery graph?
On my Google Nexus 7 I noticed that it would consume around 1% of battery each hour that it was just being idle. I suspected that battery-usage during idle time could be improved. So the next night (7 hours) I put my Nexus into airplane mode, and the next morning the battery had only used 1% for those 7 hours, which proved that there was room for improvement.

Next I disabled bluetooth and set wi-fi, to be disabled when the screen is locked (changed "Keep Wi-Fi on during sleep" from "Always" to "Only when plugged in"). After a fews tests of 7 hours idle the battery was down 2 ~ 3% each time. But then I noticed in the battery graph, that the wi-fi still showed quite a lot of activity. This probably explains the difference in battery consumption with airplane-mode.

I had expected the wi-fi to be completely disabled with this setting, and the wi-fi bar in the battery graph to be almost completely black. To see the difference I manually disabled the wi-fi and then the bar is indeed completely black (the right block in the image):

I would expect the wi-fi to be completely off when the screen is locked, but looking at this question: Turning on Wi-Fi on demand that is apparently not how Android works. So now I'm wondering what the wi-fi is doing in this setting? Why does Android keep the wi-fi 'partly' enabled? If Android would still let apps do their syncing etc on a regular basis I would understand this, but this is not the case (Notifications don't come in & it even seems to cut off streaming etc), so it seems to only waste battery?

I first suspected a misbehaving app, but I checked with Wake lock detector and Network log but don't see any suspicious apps.
I guess I could use JuiceDefender or a similar app to completely disable the wi-fi when the screen is locked (and still let it sync from time to time), but that's not really the point of this question.

Upgrading a Samsung S GT-I9000 (to anything >2.1)
I'm new to Android, but my sister recently got a second-hand Galaxy S GT-I9000. It runs on 2.1, which means that it does not have Google Play. Apparently 2.2 does, and the device seems to be able to support that firmware.

When I try Google, it comes up with lots of people suggesting rooted firwmare upgrades to Jellybean rather than anything official. I'd rather not get into that just yet if there's an official route.

I've tried Samsung Kies, but it says the device is not supported for firmware upgrades. I've also tried checking Settings > About > Software update, but 'Software update' is not there.

What is the proper way to upgrade from Android 2.1 to anything higher on a Galaxy S GT-I9000? How is it supposed to work?

EDIT: I found that it should be able to officially support Gingerbread at least. Even Wikipedia mentions that as the OS.

问:
Hardware keyboard symbol [popup] problems
I am running CM10.1 (Andromadus flavor, based on Android 4.2) on a HTC Desire Z with built-in hardware keyboard. To input keys that are not present on the keyboard, there is a symbol key that pops up a dialog where the symbol can be selected. With CM10 this symbol set was somewhat complete, but with CM10.1 some of the essential symbols such as "<" and ">" are no longer available.

So my questions are these:

Is there any way to fix this behavior to give me the complete set of symbols even in CM10.1? (see answer below)

Where in the source tree is the code for this popup located? What component? I would be happy to hack it in order myself as long as I can find the relevant needles in the haystack.

Is there any app that can be used in place of the symbol popup? I am not talking about a complete soft keyboard, but rather a quick popup dialog where a symbol can be selected and inserted at the cursor position.

How would I go about modifying my keymap to for example add "<" to Fn+comma? Shifted it's a semicolon, but Fn+comma is still the regular comma.

Edit: Found the solution to the first question. The symbols aren't missing, the popup has just been split. If you have a Desire Z and are unable to find the "<" or ">" characters, hold the hardware key for "(" (press FN, then hold "G") and a popup will present "[", "{", "<". So, I have updated my question to if it's possible (and how) to modify the keymap to add characters to shifted keys on the hardware keyboard.

问:
Android music player keeps switching on party shuffle when brought to front
Since last week, every time I bring the standard Android music player to the front, it switches to party shuffle mode and skips away from the current tune, continuing to change tune every few 10s of seconds until I switch to normal shuffle or no shuffle.

It also drops the play history, so I cannot easily get back to the piece of music it interrupted this way.

Afterwards, if I do something else, for instance use the browser, when I switch back to the player, it switches party shuffle on again and starts skipping around as before.

I have tried clearing settings for the music player and restarting it after forcing it to stop, but it has no effect. I have heard that various bluetooth and network enabled stereo devices can do this sort of thing, but both are switched off. If I take it to a different place and additionally turn off the radio transmitter under *#*#INFO#*#*, it still does it, so I am inclined to believe it is not another device interfering.

As far as I am aware, it is a sudden change and I haven't updated the OS for a while or installed any apps - I have only a couple (Android version is 2.3.6 on a Nexus One).

If anybody has an idea about how to stop this sudden forcing of party shuffle upon me, I would be greatful.

There is inconsistency in connection from Android phone to Windows 7 64 bit PC
There are problems transferring files between my laptop and my phone. The symptoms I encountered are strange and I hope for a comprehensive explanation and solution to the problem

Background:

Computer Windows 7 64 Bit

Phone Android 4.0.3

Drivers are all up to date, using Windows Device Manager.

Both devices successfully paired.

Bluetooth is on.

I will describe the steps of my experience in sending and receiving below.

Sending file from computer to phone

Method 1

Right clicked "Bluetooth Devices" icon in system tray

Clicked on "Show Bluetooth Devices"

Right clicked on Bluetooth Device (my only Bluetooth Device)

Clicked "Control" → "Send files to phone"

Clicked "Browse Files..." → Chose my file → Clicked "Send"

Sending Dialog popped up

On my phone, was asked to authenticate, clicked yes

Sending complete.

In the above steps, sending is SUCCESSFUL.

Method 2

Right clicked on the exact same file I successfully sent above

Click "Send to → Bluetooth"

Bluetooth Send Wizard pops up

Clicked "Next" → Selected Bluetooth Device → Clicked "OK"

Displayed Error Bluetooth device not found. Please verify that your Bluetooth device is properly connected and turned on.

In these steps. sending is NOT successful. Please help me identify why.

Next, I will move on to sending file from phone to computer:

Method 1

Using the exact same file on phone, tapped "Send via Bluetooth" → On the phone displayed Bluetooth share: Sent 1 failed. On the computer nothing happened, no notifications at all.

In these steps, sending is NOT successful.

Method 2

Clicked Start button → Typed "fsquirt" in Run

Bluetooth File Transfer dialog popped up → Clicked "Receive files"

Displayed Waiting for connection

On phone, tapped the same "Send via Bluetooth" → Bluetooth File Transfer on computer shows sending progress → Sending complete.

In the above steps. sending is SUCCESSFUL.

Question:

Can someone explain to me the discrepancies in my experience in sending and receiving between the computer and phone? The 2 devices are obviously connected and sending is possible, so why does 1 method work while another does not? What happened?

Edit:
I shall refer to the above sending and receiving methods as Sending 1, Sending 2, Receiving 1 and Receiving 2.

When 'Control' dialog box with the "Send files to phone" option is opened,

Sending 2 becomes SUCCESSFUL

Receiving 2 becomes NOT successful.

How to revert Samsung Galaxy Mini S5570 to stock Gingerbread?
Here's the situation: I got this Samsung Galaxy Mini as a gift - my first smartphone - but with this obscured operating system called [DEV][WIP][ROM][UNOFFICIAL] Android 4.2.2 CM10.1 - Nightly 20130310. It doesn't do even some basic things, not the best way to be introduced to smartphones, right? But what can I do?

So as my first interaction with smartphones now supposed to hack a usable operating system on it as well. Let's do it. My obvious choice was to go with the latest official CyanogenMod for the system: you can read my efforts into that here: https://android.stackexchange.com/questions/42088/adb-push-doesnt-push-myrom-zip-sdcard-though-it-says-it-copied-the-file-sams (So far no answers yet.)

My guess at this point is things could work out better if I could first revert the phone back to the official ROM. My first try was to plug it into Samsung's KIES software - but obviously it doesn't recognize the now totally hacked phone. The XDA Forum is way too overwhelming for me to go for this - as my first venture into smartphones -, could you point me to a no-nonsense, step-by-step guide how can I revert back the phone to official Gingerbread from here?

I don't have enough rep. to comment under other's post, so I had to open this thread. I read some threads on Google Maps here and the question still persists.

Is there a straightforward method to cache my city's map strictly onto the SD card (as I am running out of internal space), possibly in a way that this cache doesn't get deleted in 30 days? On the other hand it would be cool if it auto-updated itself with the latest map updates, points of interests from Google, strictly when on Wi-Fi.

I already heard of Google's native solution, and of Brut Mod -- but don't know if any of the two would come close to my goal. How can I achieve it?

Edit. Added link for Brut Mod. Sorry, don't have the link any more for that other question.

HTTP not accessible on laptop connected to Hotspot?
I have the $60 unlimited MetroPCS LTE plan. The hotspot works on my laptop and MP3 player, but I can't browse websites that aren't in secure mode on the laptop. Are they blocking port 80, or is there something else I can do to configure this?

The phone is not rooted, and also it's not malware-related or a network misconfiguration on my laptop. HTTP mode works fine when connected to other networks.

Any thoughts?

How to add a shortcut directly to the 'Alarms' and 'World Clock' tabs of the stock HTC Clock app?
I have QCustomShortcut installed and I'd like to be able to create a shortcut directly to the 'Alarms' and 'World Clock' tabs of my HTC stock Clock app (com.htc.android.worldclock).

The app has an activity called com.htc.android.worldclock.AlarmClock but creating a shortcut to that doesn't work.

I have already tried the following apps but they just open the Clock app on the first tab instead of the third:

Alarm shortcut by Alexandr Ivanov

Alarms shortcut by Matthieu Guenebaud

Alarm Clock Launcher by Slipstream Apps

It should just be a case of defining the correct action, package and class in QCustomShortcut but I'm stumped.

Read/Write not working on external sd card - Android
I have a Samsung Galaxy S2 and no applications can read or write to the external SD card - except the Root Browser. This happened a month or so ago after I installed a custom ROM (Alliance) and I have lived without access to the external SD card since.

Since then, an application has managed to create one folder on the card that is accessible to a regular file manager (such as ES File Explorer).

When I use my PC to access the SD card, all is fine and visible, so I have deduced that it must be something in the android config files. I have checked
/system/etc/permissions/platform.xml
and I have

问:
Google Now "time to leave" notifications are late
When I first got my Nexus 4, the "time to leave" notifications from Google Now were reasonable. I'd get a notification at 9:30am saying that I should leave at 9:45am for a calendar appointment.

After a few weeks, however, the notifications stopped arriving at a sensible time. The best case scenario is that I'll need to leave at 1pm for an appointment and get a reminder at 1:15pm (after I'm already on the road) saying that I should leave at 1:15pm to arrive on time given current traffic. I may also get a notification at 1:15pm saying that I need to leave at 1pm. Since I don't own a time machine, this isn't very helpful. This happens for all of my calendar entries that have an address. The late notifications are rather consistently 10-15 minutes after the time that I think I should leave for a destination.

I found this question which might be related, but my notifications are showing up late rather than displaying absurd times.

Is this a known issue? Is there a workaround?

Update

The alt-text for today's XKCD is

It ships with a version of Google Now that alerts you when it's too late to leave for your appointments.

That seems to confirm that this is a bug other people are experiencing, but I haven't had much luck finding bug reports about it since the search terms are too common.

I need remote access to my MyTouch 3G Slide using a web interface with no access to the phone
I have a MyTouch 3G slide that is currently in Missouri and I am in North Carolina.  I have my Google Play account information and access to a PC.  The phone is not password locked but it is plugged in and has signal, no WiFi.  There are some apps I've seen that can install and as long as you accept the permissions in Google Play it will install and auto run without user interaction.  I've tried AndroidLost but I cannot get a stable enough connection to get the files and information I need.  Basically, I would like to access my SMS, MMS, phone logs, pictures and my stored files.  I thought maybe the AndroidLost App Launcher would help but to no avail.  I know all the phone info like IMEI and IP address using AndroidLost.  I just need an app that will activate and register itself with the phones gmail or by me sending an SMS with an activation code and it receives it.  Not that this may matter much but I'm stationed in Missouri and I'm in Fort Bragg right now for a school and being able to interact with my phone using my browser is detrimental to me right now, thank you in advance for any ideas!</p>

Importing SSL certificate for email
I am having trouble importing an SSL CA certificate to authenticate my mail server.

My mail server is run by Dreamhost, which offers TLS on their IMAP/SMTP servers, but with a certificate signed only by them (not obtained through Verisign et al).  I have their root certificate file ndn.ca.crt and it works fine on my computer (I put it in /etc/ssl/certs with an appropriate symlink, and then firefox, pine, etc are able to verify Dreamhost's server).  Now I'd like to use it on my new Android phone (4.0.4).

I've tried importing the certificate: I copied ndn.ca.crt to USB storage and went to Settings > Security > Install from device storage.  I get a "Certificate name" dialog box with "ndn.ca" prefilled, saying "Package contains: One user certificate"; I touch "Ok" and see a popup "ndn.ca added".

However, when I touch "Trusted credentials", there is nothing listed under the "User" tab.  And when I try to select TLS or SSL as the security type in the Email app, I get the message "Setup could not finish: Cannot connect safely to server".  If I use "TLS (Accept all certificates)" it works, but of course this doesn't actually protect me against a man-in-the-middle.

Any ideas what could be wrong?  I've read the question How do you import CA certificates onto an Android phone? but it seems to be mainly concerned with getting the certificate in a recognized format, and doesn't help me.

ssh over wifi vs broadband weirdness
I have a really weird issue with connecting to an outside host from my android device (2.3.6) using ssh. I have no problem with connectbot actually, but when working on a terminal the weirdness kicks in. I've tried several solutions (terminal-ide, rsync4android, kbox) and the symptoms are all the same.

If I'm connected to the net through the broadband link everything works find, host resolution, ssh, etc.

However if I'm connected through my home wifi router host resolution doesn't work and neither does ssh (connectbot still works over wifi, but none of the terminal based solutions). It simply hangs when I do "ssh host.com" or "ssh x.y.z.v" so it doesn't matter if I use IP numbers or the domain name.

I thought this has to do with the firewall setup on my wifi router, but on my laptop everything is working without a problem, I can ssh to any host, etc, and on the laptop the connection is also through the wifi router.

So to summarize this is situation:

connectbot on device: works with both wifi and broadband

terminal/ssh on device: only works with broadband

terminal/ssh on laptop: works with wifi

I should add that ping, wget, netcat, etc. all work from the terminal to the outside host also on wifi so the problem is ssh-specific.

What can be the reason? Any hints would be greatly appreciated.

Unfortunately strace or the -v and -vv options for the ssh client are not available on android, so I'm really at a loss how to debug this.

In case you are interested why I don't simply use connectbot and forget about the terminals: I'd like to use rsync eventually which would operate over ssh.

How can I edit a prior predictive search?
When typing a URL into my Cyanogenmod phone's browser, as I type, it suggests URL(s) from prior browsing that match what I have typed, similarly, when on a Google web search page, if I begin to type in a search string, the phone offers prior searches that match what I have typed in thus far in a drop down list from which you can select.

This is a great feature, but sometimes, I want to take the prior history and modify it slightly or append to it.  This is especially common with a search where I want to add more words to my prior search.

Is there anyway to somehow select one of the suggestions without immediately invoking it and thus allowing me to edit it slightly before submission?

This is not the standard device on recognized ordeal but a device is not even being detected at all in any way by the PC.

The phone is the Samsung galaxy ace.

and the OS is Windows 8 professional x64.

Tried installing kies and re-installing.

I'm using the stock cable and the windows 7 drivers (no windows 8 drivers available).

I've went through the usual reset of the phone, formatting of the phone.

Tried all the available USB.

I tried the troubleshooting pack cabinet from windows for hardware changes on windows 8 to no result.

I've messed with all the settings for development on the phone etc etc.

Been in device manager looking for some information on it but it is not listed.

The phone with the setup it has just now works perfectly with windows 7 on another PC of mine and I can debug and deploy to the mobile via that but it is not my primary work station. (without kies!)

The phone still charges and buzzes but the PC gives no response :/

It seems that I managed to enable "mousekeys" on my android. How do I disable it?
I have a Samsung Galaxy Note 10.1. I am using it with the Apple Bluetooth Keyboard. From time to time, I use a VNC client (androidVNC or FreebVNC) to connect to different machines.

At some point I must have pushed some magical key combination on the keyboard, which enabled the "mousekeys" mode. Namely, the arrow buttons on the keyboard now control the mouse (in the VNC window) rather than act as arrow buttons.
It is not specific to the wireless keyboard. The "Hacker's keyboard" input method (which also has arrow keys) behaves identically.
It is not specific to the machine I am connecting to - it seems the key-to-mousemove translation is happening on the android side.

In all apps except for the VNC clients the arrow buttons work as expected. However, as the problem appears for both androidVNC and FreebVNC applications, it is obviously not a matter of misconfiguration of a particular VNC client. Rebooting does not help.

Hence the question - could it be that I managed to somehow enable the "mousekeys" mode for the android by pushing something? Is there a way to disable or at least to debug it? I have root access.

So far I managed to find out there is something fishy about Linux+MouseKeys+VNC.

I use Dropbox to sync them to my PC, so I don't usually connect my phone via USB to the PC. After seeing this issue, I browsed via USB to some of the images that appear in the wrong position and it looks like the EXIF date is correct, but, for some reason, the phone shows a different hour for this images in the "Details" section. It appears as if it misreads the hour when indexing them, showing them as having been taken one hour before the date in the EXIF data.

I have tried to clear the cache of the Media Storage application and restart the phone, but, unfortunately, this did not do the trick and I think that a few more images got mixed up after it finished rescanning.

Does anybody have any idea what might cause this bug and how can it be fixed?

PS: I installed Total Commander on the phone and it displays the proper date for the images and it also picks them up in the expected order, so this is clearly a bug in the Media Storage app.


问:
Use nvflash to install recovery compatible with CM10.1
I have a Dell Streak 7 that had some sort of weird "read only" glitch from the factory.  I recently was able to successfully get CM10.1 on it using the files and instructions (nvflash bat file) found here: http://forum.xda-developers.com/showthread.php?t=2130081

However, when trying to flash gapps I discovered I cannot enter recovery mode in any way.  I've tried volume up + power, and the orange battery light flashes 4 or 5 times then nothing.  Using ROM Manager Premium and the android power menu to "Reboot to recovery" just boots straight back into CM10.1.  I've also tried reinstalling CWM via ROM Manager and experimented a couple times with nvflash without luck.  Depending on the commands I've tried it just says "NVFlash Started" or "[Resume Mode]" and just sits there forever.

I cannot use fastboot because I can't get the ADB drivers working on my windows 8 machine (I've tried Dell and Google drivers, I have disabled signing, it just doesn't recognize the device correctly).

So what I'd like is a link to an appropriate recovery image (I don't care if it's CWM or TWRP or whatever) and the appropriate command to flash it using nvflash.

Syncing Google Calendar on Android 2.3.4 Gingerbread
I've got an Android Gingerbread device. When I go to Settings -> Accounts & Sync -> Manage Accounts (and click on my email address) -> Sync Calendar, I see an exclamation mark besides the sync icon (the one with the two arrows forming a circle), and a message below the entry saying "! Sync is currently experiencing problems. It will be back shortly."

Why do I get this message? Can I get things to work by say, installing CyanogenMod? (I am using an LG P690 Optimus Net.) I've heard LG phones tend to have more bugs than other brands such as Samsung, is this true?

My phone seems like it is sending MMS messages, but they never actually arrive - what's going on?
There are several MMS problem threads on here, but none seem to get at the issue I'm having. I can receive MMS messages just fine, however I cannot send them.

How to use phone as an USB Wi-Fi adapter?
I would like to use my SE Xperia 8 with 2.1 as an usb wifi adapter to my PC. What I would like to do is set it to access point mode and share my ADSL internet with my laptop through wifi.

I would connect the phone via an usb cable and I would like to be able to route and share my pc's internet through it to and back from my laptop.

I don't mind if the firmware must be changed as I have an other phone. But I prefer if there is easier/more convenient way to do this. On the pcs I'm also flexible about OSes.

How could I use my phone as an wifi adapter?

EDIT To make it more clear, here is what I mean:

I have:

"PC A" with internet over ADSL. no wifi.

my phone, it has an usb cable and a wifi chipset.

"PC B" with wifi

What I would like to do us to use PC A's internet on PC B, with the help of my phone.
Connect Internet to PC A, then connect my phone to PC A, then connect PC B to my phone via Wifi, and use PC A's internet on PC B.

Internet >>> Adsl modem >>> ethernet cable >>> PC A >>> USB cable >>> phone >>> wifi >>> PC B

问:
Cant see device with lastest adb.exe version but I can see it with an old adb version in Windows
My device is a Wolder Manhattan 7" Android tablet which is a clone copy of BQ Pascal 2.

In order to get root and use adb, most guides use the BQ Pascal 2 Windows drivers for Wolder Manhattan:

http://www.htcmania.com/attachment.php?attachmentid=110451&d=1334723079

My system:

- Windows 7 Ultimate 64 bit.

- Latest version of the Android SDK installed (adt-bundle-windows-x86\sdk\platform-tools).

Driver setup:

I have followed the guide to install the drivers and they have been installed perfectly in Windows.

The device is shown in Windows Hardware Devices Manager as: "Android Phone - Android ADB Interface."

"USB Debugging" and "Mass Storage" is enabled and Im already "root" in my device.

Tests with adb versions:

Using adb.exe version  1.0.31 (from the latest SDK) (796kb) doesn't show any connected devices:

```<code>...\adt-bundle-windows-x8\sdk\platform-tools>adb.exe devices
List of devices attached
</code>```

Using and old adb.exe version 1.0.29 from 2012 (158kb), which is in the BQ Pascal 2 drivers, the device is shown:

```<code>...\Root Pascal 2\RooT\files>adb.exe devices adb server is out of date. killing...
daemon started successfully
List of devices attached
0123456789ABCDEF        device
</code>```

Question:

Why does the old adb.exe version from 01/11/12 work and shows the device, and the lastest one from the Android sdk doesn't show anything?

I have also tested with other drivers but I get the same result, the device is only shown using the old adb.exe.


问:
After rooting my verizon Galaxy S3, I have no data or cellular connection?
So, when I first rooted my phone, everything worked fine. I had used CM 10.1 (Or at least some version of Cyanogenmod). Being curious, I wanted to try other ROMs. I then installed MUIU v5. Didn't like so I went back to a backup I had created previously, and updated to the latest version of Cyanogenmod. When I go to Settings->About Phone->Status, I see these settings:

```<code>Network: Verizon Wireless
Signal Strength: -97 dBm 1 asu
Mobile network type: CDMA - 1xRTT:7
Service State: In service
Roaming: Roaming
Mobile network state: Disconnected
My phone number: ***-***-****   --Giberish which ISN'T my phone number
MIN, MEID, IMEI, ICCID all give me long numbers.
IP Address: Unavailable
</code>```

This is when Airplane Mode is off. My little signal icon in the top status bar has an R which I'm guessing is for Roaming.

I have no idea why it's doing this seeing that it worked fine before on Cyanogenmod. What can I do to get my signal and data connection back? What would have caused something like this?

How to rebuild or refresh slow Motorola Defy
My friend has a Motorola Defy which is beginning to run very slowly and reboot itself at random. He's had it for a couple of years.

He doesn't have enough money right now to get a decent replacement so I suggested there might be ways to get a few more months out of the phone.

Installing a brand new/ clean operating system seems like a good plan. I've had a look at Cynogenmod but I'm not sure if that will achieve what we're after.

In the case of a slow Android phone is the best approach to install a new OS? Or are there ways of cleaning up/ speeding up the OS without going to that level?

If we were going to install a new operating system is Cynogenmod the best approach?

I noticed this question explaining how to return the Defy to it's original stock state: Return my motorola defy to its original state


问:
What is the difference between CFAutoRoot and CFRoot?
I wanted to "root" my Android phone. Therefore I went to the XDA forums to download the root package. I found two versions of it: CF Auto Root and CF root.

I thought one has to modify the kernel to obtain permenent "root" rights. Therefore it was justified that the CF Root package is nothing but a modified kernel. However, I didn't quite understand what the CF Auto Root does that is different? Isn't it also a modified kernel??

What does the author mean when he says this:

CF-Root (non-Auto) are manually built rooted kernels and/or flashables
  that usually provide more than “just root”. CF-Auto-Root is built on
  an automated system that I am constantly improving that takes a stock
  recovery image and returns an automated rooting packages. These
  packages are designed to install and enable SuperSU on your device, so
  apps can gain root access, and nothing more.

What does he refer as "automated" system??

问:
SSH server when phone is sleeping: possible?
I an running the Dropbear SSH server on CyanogenMod 7.2.  Is there any way to setup my phone so that I can connect to it over wifi even when it is in sleep mode?  I don't mind if there is a small hit on the battery.

If not, is there a way to at least allow an rsync over ssh to proceed after the screen blanks out?  The strange thing here is that if I initiate an ssh shell connection, the command line is still usable after the phone goes to sleep, however it is very slow (changing the CPU governor didn't seem to make a difference).  Rsync seems to freeze when the phone sleeps.

I tried echo hello > /sys/power/wake_lock, to no effect.

HTC One and Sendgrid SMTP outgoing mail server not working
I am using Sendgrid SMTP server for my emails on the default Mail cleint and I've set up the account on my HTC One android phone. The problem is it doesn't send emails, it keeps saying authentication failed. I've tried every combination of ports/ssl/tls and the same thing. My username/password is definitely right as I use it everywhere with no problem. I've contacted Sendgrid support but they can't figure out any problem with their servers so it may be just the way the Mail client communicates with their server. Other SMTP servers work fine on the phone, just Sendgrid doesn't.

Has anyone has problems like this with their outgoing mail servers?


问:
MMS not working on CM9 ROM
I have an LG Optimus V (Virgin Mobile) running CyanogenMod 9.  The ROM I am using is located here: https://sites.google.com/site/bobzhomeroms/vm670ics

According to his ChangeLog, MMS should be working, but in reality it's not.

Some Google searching told me that my APN might be the problem.  I dumped the APN XML file from my phone, and it looks like this:

```<code><?xml version='1.0' encoding='UTF-8' standalone='yes' ?>
<apns count="1">
  <apn
    name="Virgin Mobile"
    numeric="31000"
    mcc="310"
    mnc="00"
    apn="0"
    user="null"
    server="null"
    password="null"
    proxy="null"
    port=""
    mmsproxy="205.239.233.136"
    mmsport="81"
    mmsprotocol="null"
    mmsc="http://mmsc.vmobl.com:8088/mms?"
    type="mms"
  />
</apns>
</code>```

I also checked my build.prop file, and found these 2 lines:

```<code>ro.cdma.home.operator.numeric=311490
ro.cdma.home.operator.alpha=Virgin_Mobile
</code>```

All of my research shows that these settings should be correct, but I still cannot send or download MMS messages.  What else could be wrong?  I've heard people having luck with replacing the mms.apk on their phones, but I don't know which to use, or even where to find a replacement.

how to lower boot up time? (many apps 122, rooted device)

[old subject: link2sd not mounting second partition, "quick restart"
  fails too]

[IMPORTANT: boot time took 20 minutes, see at the end...]

My phone suddenly reboot (while I was sleeping), and from that on,
  link2sd fails to mount the 2nd partition that was working flawlessly
  for a long time.

Now, everytime I boot, it freezes on black screen, until I unplug the
  sdcard, then it shakes and continues booting. After plug the sdcard
  back it seems to create this device: /dev/block/mmcblk1p2 (instead of
  mmcblk0p2).

After I re-insert the sdcard, link2sd fails to mount again, I recreate
  the scripts, do a "quick reboot" but it fails again. (I guess it was
  expecting mmcblk1p2 but sdcard was now back at mmcblk0p2).

I plug the sdcard on pc and the 2nd partition data is there, it is
  ext3, all seems ok there.

This
  Partitioned sdcard not working with link2sd,
  does not work for me :(

I changed the script at
  /data/data/com.buak.Link2SD/files/init-link2sd.sh that was created
  with mmcblk1p2 to mmcblk0p2. After that, a "quick reboot" wont work
  despite I got /data/sdext2 mounted (manually with terminal).

A normal reboot sends me back to the black screen, my guess is I have
  "created a linked app" that may have widget but I dont know which one.
  I tried a few I remembered but didnt work, still same problem...

I am still fighting with this... I will try more tricks and report
  later...

Any tips (tricks) ?

EDIT: I used adb logcat (found good tutorial here:
  http://www.howtogeek.com/125769/how-to-install-and-use-abd-the-android-debug-bridge-utility/)
  and the last log message was:

```<code>D/dalvikvm( 1506): GC_FOR_MALLOC freed 830K, 37% free 6859K/10759K, external 1429K/1581K, paused 77ms
</code>```

After that it froze, I started it again and it brought more log than
  before...

After 20 minutes, the phone finally completely boot up! thats too much
  time... now it seems to be working ok... At this point my question
  changes to "how to lower boot up time?" is it ok to change the
  subject?

subject: how to lower boot up time?

So scanPackage took too much time and I am uninstalling not needed packages... I guess it is good to keep the other research info I did so people can come here and understand they just need to wait a long time if they have too many apps installed on a not so fast device.

Android stock mail app does not retrieve IMAP mails
Last week my native Android mail client stopped retrieving mail.  It can still send mail.  An identically configured K-9 mail app does retrieve email.  The server is a dovecot mail server, both clients use the IMAP protocol.

When the Android native client connects, it sends:

```<code>239 SELECT "INBOX"
240 UID SEARCH 44:68 NOT DELETED
241 NOOP
242 NOOP
243 CAPABILITY
244 LIST "" "INBOX.*"
</code>```

The server's reply to the UID SEARCH:

```<code>* SEARCH 11201 11202 11203 11204 11205 11206 11207 11208 11209 11210 11211 11212 11213 11214 11215 11216 11217 11218 11219 11220 11221 11222 11223 11224 11225
240 OK Search completed (0.000 secs).
</code>```

These results look exactly like the results the K-9 app gets.  Any idea why the native client does not pickup the mail?  It doesn't show any mail at all.

Is there some app that allows me to answer phone calls with my computer?
Is there an app that allows me to answer phone calls with my computer? Sometimes it's uncomfortable to receive phone calls with the headset of my smartphone, it would be nice to talk when receiving a phone call through my computer headset which is way more comfortable.

Note: No, there isn't a comfortable headset in the near markets.


问:
Indic font(Kannada) is not rendering properly in Android ICS
I am trying to get the kannada font support for Android ICS. I rooted my Xperia Neo L phone which is running Android ICS 4.0.4 and installed Kannada font (Lohit-Kannada.ttf). I have also included the Lohit-Kannada font as family-set in fallback_fonts.xml in the framework. After that, I am able to see the kannada fonts render in browser but the complex script is not supported. Glyphs are not rendered in proper way, though it is just readable. Other indic languages like Tamil, Hindi, Bengali etc renders perfectly but my language is not rendering properly.

Someone suggested me to go thru this blog. But i'm not able to find out where to make those file changes. I mean where is that lohit-fonts directory, where is the android.mk file? I'm not able to find those folders or those files in my phone. Any help please?

No Permissions Error Regardless of sudo or shell
I have a Huawei comet u8150 That I decided to root seeing as I'm stuck with it for the time being. I rooted it last night, Flashed Clockwork Mod Recovery 5.0.2 and Installed CyanogenMod 7 for the U8150. Now before I installed Cyanogen I was able to access the device via adb using sudo -s and starting the server via a root shell. Now I can run it as sudo or a root shell and I get the same issue. Inside of 51-android.rules I have

and my output of lsusb is

You can see that 12d1 is included inside of the 51-android.rules file, so I'm not sure where to go from here as everyone tells me to drop to a root shell which has not worked as well. Thanks in advance.
---UPDATE---
Thought I'd give some extra input on the matter real fast.
If I perform an adb pull or an adb shell that seems to be working. However when I try to utilize adb push or nano while in the superuser adb shell I don't have permissions to modify. It recognizes my device, but that's it.
I'm sure I have the rules set correctly, but the problem is I can use

sudo -s

and operate from within the root shell and I have the same output when using adb devices. Hopefully someone will have some thoughts as to what's going on.

问:
video recording distorts vertical lines
Here's a problem I've noticed on all Android, from old 2.2 to the new demo tablets at the store:

When in camera video mode, record a column or a pillar, and slightly rotate the device back and forth left/right. Notice that the column appears to be changing shape, wobbling.

I remember seeing in consumer-reports or similar magazine that most Android phones have worse video quality, I think only G2 had a very good rating.

I wonder if there is any known fix for this problem? Which models don't have this bug?

What can I do to make it download again?
