5,715,678 | 5,715,679 | Multiple Screen Size support for android? | <p>I am creating a simple <code>layout</code> in android with some customized buttons(not the ones android provides by default).The image appears proper on screen size 2.7 to 5.1. However <code>buttons</code> appear stretched on screen size 5.4 and greater (tried till screen size 7).I have made four same images named them similarly of different densities and placed them correspondingly in the folders <code>ldpi,mdpi,hdpi,xhpi</code>.I need to know whether i need to create different <code>layouts</code> for different screens?Or android picks up images automatically from the corresponding folders?Some body please guide me as i am new to android on this as i am struggling to create <code>layouts</code> targeting android mobile devices.</p>

3,010,813 | 3,010,814 | scripting gmail bulk fowarding, IMAP not an option | <p>Constraint justifying script: IMAP is not an available option. I am working with Gmail enterprise and the option has been made unavailable.</p>
<p>This script needs to bulk forward gmail by user defined label and include message recipient, sender, subject, and date. It can successfully forward messages; however, given Gmails list of methods, I am not sure how to get the messages forwarded while maintaining its original above info.</p>
<p>Here is my script:</p>
<pre><code>function forwardMail2() {
var data = SpreadsheetApp.getActiveSheet().getRange("A2:B11").getValues();
for (i in data) {
var row = data[i];
var name = row[0].toString();
var email = row[1].toString();
var label = GmailApp.getUserLabelByName(name);
if (label && (email != "")) {
var threads = label.getThreads();
for (var x in threads) {
var messages = threads[x].getMessages();
for (var y in messages) {
/* var addressee = messages[y].getTo();
var mailSender = messages[y].getFrom();
var date = messages[y].getDate();
var subject = messages[y].getSubject();*/
messages[y].forward(email);}
</code></pre>
<p>Here are examples for the Gmail method forward() I have come across so far:
// forward first message of first inbox thread to recipient1 & recipient2, both @example.com</p>
<pre><code>var firstThread = GmailApp.getInboxThreads(0,1)[0];
var message = firstThread.getMessages()[0];
message.forward("[email protected],[email protected]");
</code></pre>
<p>and </p>
<pre><code>var firstThread = GmailApp.getInboxThreads(0,1)[0];
var message = firstThread.getMessages()[0];
message.forward("[email protected],[email protected]", {
cc: "[email protected]",
bcc: "[email protected],[email protected]");
</code></pre>
<p>The optional advanced arguments for the Gmail forward() method do not pertain to the additional info I am trying to include.</p>

<p>Before you ask what I've tried, nothing, because I don't know how to phrase a Google search and I have no idea how to do it.</p>
<ol>
<li>How do I make it all in one window. For example, when the user clicks a choice, it either closes that window and makes a new one with the next scenario, or it just changes what's in the current question. Example:</li>
</ol>
<p>Hey, what do you want to do!
A.
B.
C.
D.</p>
<p>Then it goes to:</p>
<p>Cool! You picked C. Now do you want to...etc etc.</p>
<ol>
<li>I want to have a time limit on the choices, so the user has to rush (the genre of the games dictates this for realism). I wanted the scenario to come up, then a button that says "I'm Ready!" or something, then the choices come up, and they have like 10 seconds to pick or the game would say You Lost. It would do this for every choice. I don't care if there's a timer, but if you can easily teach me how to do it, that's cool.</li>
</ol>
<p>I'm not entirely stupid, you don't have to post full code, just a basic idea (unless you want to, idc). Thanks.</p>

3,307,464 | 3,307,465 | C++ middleware assignment | <p>I have a rather large assignment for my Programming II class. We are to take a system that we currently use or have access to and develop a middleware program that runs and does something new for you or improves upon middlware that is already there. Originally I was going with writing a middleware program that uses my home network and shares all music files from my computer, another computer, and puts in on an MP3 player or can take documents from one computer and send it to the other or send to wireless printer. I now realize this is much to much of an undertaking for a beginner like me to take on. So...I started web searching to see if I could find any ideas there are dumbed down and more simplistic for my level of education and experience (none), so far I am not having much luck. My question is this:</p>
<p>Where can I find good solid information and examples to study and figure out how I am going to implement middleware into a small home network (that is the only system that I have access to)? I have looked at ACE and CORBA and they are too complex for the needs that I am looking at. Any help on this is great, thanks in advance.</p>

3,792,543 | 3,792,544 | Python: Check an index against multiple other indexes | <p>I am using Python and I would like to check the location of a value in a list of lists against other indexes.</p>
<p>Like if I had 1 at (1, 1) I would want to be able to check if 1 were at the other indexes so I could make something happen based on which index it matched. </p>
<p>For example:</p>
<pre><code>list_of_lists = [
[4, 5, 6],
[7, 1, 8],
[6, 2, 9]
]
if 1 in row for row in list_of_lists:
if index of 1 is (0, 0), (0, 1), or (0, 2)
print ("It is in the First row!")
if index of 1 is (1, 0), (1, 1), or (1, 2)
print ("It is in the second row!")
</code></pre>
<p>If this worked correctly it should print: "It is in the second row!" Because the index of 1 matches with one of the indices in the third if statement. They may not necessarily be rows in some instances where I would be using this. So If you could provide a way that would not use the rows in your answer. Just a way to look at indexes and compare them. Obviously this is not the correct syntax. But how would I do that in Python? How would I get the index of 1 and compare it to other indexes in a list of lists?</p>

{MANAGE_SUPPLY,
MANAGE_CUSTOMERS_SERVICE,
ORDERS_MANAGEMENT,
REPORTING_OPRATIONES}

<li>Is there TryParse available or every time I parse I should try and catch ?</li>

1,345,258 | 1,345,259 | PhoneStateListener events stop receiving sometime | <p>My application process incoming/outgoing calls and shows some UI.
So I use PhoneStateListener to listen changes such as CALL_STATE_IDLE , CALL_STATE_RINGING ,CALL_STATE_OFFHOOK. on receiving call to my BroacastReceiver for incoming/outgoing call. </p>
<p>Most of the time things work properly. But sometimes my application does not receive events of PhoneStateListener and hence it is not able to change/clear UI. From user feedback this typically occurs on HTC Hero. But I have came across this issue sometime on other devices also.</p>
<p>My first guess is that android is killing my application in midway during call due to memory requirement. If so, is there any way to ensure that android does not my kill application under such situation .</p>
<p>Any thoughts ?</p>
