</blockquote>
<p>This is the first time I ask in Stack overflow.
For some reason I have a chance to get one of these Android phones for testing apps :</p>
<ul>
<li>Samsung Galaxy Nexus</li>
<li>Samsung Galaxy S 2</li>
</ul>
<p>After days searching for information, I see that a good Android developer's phone should be :</p>
<ol>
<li>a "with Google" phone, so it has the most original Android OS, and often get updated OS early among Android phones.</li>
<li>has a stable, or upgradable to, Android 2.3 or nearby on it, since the market of 2.3 is the largest at this time.</li>
</ol>
<p>When it come to the point, an experienced friend of mine say "Yes" with S2, though I love Nexus more... But still I can't decide on which one I should take, since there's something not clearly :</p>
<ul>
<li><p>If choosing S2, will the theme "Touch Wiz 4.0" on S2 affect my testing and debugging process later ?</p></li>
<li><p>If choosing Nexus, can I safely, easily downgrade the Ice Scream Sandwich (4.0) to Ginger Bread (2.3) ?</p></li>
</ul>
<p>So... can you help me deciding this ?
It would be great if you explain your reason, too. Thank you ^^</p>

68,959 | 68,960 | How to pick contacts only from google contacts (not facebook etc) with phone numbers? | <p>I need to fix a bug in an old app of mine. Part of the bug is how I select contacts. Here is what I need:</p>
<ol>
<li>The contact must be from the
'normal' google contacts list, i.e.
I don't want to get any contacts
from facebook or similar.</li>
<li>The contact must have at least one phone number.</li>
<li>The contact must be from the old <code>android.provider.Contacts</code> provider.</li>
<li>If I can use an Intent to fetch the contact URI without having to create the selection list etc myself, then that is a bonus.</li>
</ol>
<p>Sounds simple, but I am really struggling. This is what I am trying:</p>
<pre><code>@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent = new Intent(Intent.ACTION_PICK, Contacts.People.CONTENT_URI);
startActivityForResult(intent, PICK_CONTACT_REQUEST);
}
</code></pre>
<p>That works OK. I still see contacts without phone numbers, but I can live with that. Worse though is that I still see facebook contacts in the list! This seems to be in contradiction to the following quote found at the <a href="http://developer.android.com/reference/android/provider/Contacts.html">Froyo API for the deprecated Contacts content provider</a>:</p>
<blockquote>
<p>The APIs have been superseded by ContactsContract. The newer APIs allow access multiple accounts and support aggregation of similar contacts. These APIs continue to work but will only return data for the first Google account created, which matches the original behavior. </p>
</blockquote>
<p>That sounds like exactly what I wanted, but alas, not what I got. </p>
<p>Finally, here are my concrete questions that I hope someone can answer:</p>
<ol>
<li>Why am I seeing Facebook contacts when using the android.provider.Contacts content provider?</li>
<li>If this doesn't work, how else can I get the user to select a google contact with a phone number?</li>
</ol>
<p>Many thanks.

While I am just at the beginning of development, I want to make sure I am going in the right direction to avoid re-coding later. Much like java source code is not meant for the end user to be seen, neither are .sql files and commands. My main goal is to hide them from the end user. My approach is as follows, and I am seeking alternative approaches and suggestions:</p>
<p>Write a small program that loops through all .sql files in a directory and stores the contents into a java.util.map using bufferedInputStream. The Map will be constructed with = new HashMap(, ). (I believe this is correct syntax). The key will be the .sql file name and value will be the .sql file contents. Then, serialize the Map object into a single file (say "SQLBin.bin") using ObjectOutputStream. Place the SQLBin.bin file into the resources folder of the main project and then use .getResourceAsStream() to access it and recreate a Map object in the main application. This will then allow me to access the SQL commands by simply referring to the .sql file by name in the Map object.</p>

4,055,569 | 4,055,570 | Problems with android GridView | <p>I am trying to display 2 columns of text in a GridView in android. I create a TextView for each cell of the grid. Everything seems to work well until the TextView tries to wrap the text to a second (or more) line. When this happens, sometimes the second line of text overwrites the next cell, rather than causing the cell to expand to fit the text. All I have to do to get the text to display properly is click one of the cells in the grid. This seems to cause the grid to repaint and then everything gets displayed properly. I have tried any number of things to fix this problem but nothing seems to help.</p>
<p>Is there some property that I have to set on the TextView or the GridView to allow the cells to expand to fit the text? Or is this just a glitch in GridView that I have to live with?</p>
<p>BTW, setting android:singleLine="true" prevents the word wrap and solves the problem but it isn't an ideal solution because I really don't want the text to be truncated.</p>

2,713,711 | 2,713,712 | Does a union always have default value of zero? | <p>Please let us consider following code:</p>
<pre><code>#include <iostream>

int main(){
int k=5;
cout<<k+u.i<<endl;
system("PAUSE");
return EXIT_SUCCESS;
}
</code></pre>
<p>This code shows me output 5,what means to me is that,variable i in union structure has default value=0, but the same code on ideone.com shows warning like this</p>
<pre><code>prog.cpp:6: warning: non-local variable ‘<anonymous union> u’ uses anonymous type and then prints 5 as well, and last one core of this problem comes from algorithm calculate

union{
float x;

u.x=x;

return x;
}
int main(){
float x=234;
cout<<invsqrt(x)<<endl;
return 0;
}
</code></pre>
<p>It shows me output also,but my question is that is it a this code good?i meant that because int i is not initailized ,can any compiler consider it's value as zero?i am curious and please tell me something about this,also if something is not clear from my question say me,i am not English native speaker.</p>

4,315,336 | 4,315,337 | login into local FTP server with ip | <p>I am trying to log into a FTP server that I am only running locally in my network.

<p>Can anyone look at my code and see if I am making any error that may be the cause of this address issue? Also I can log into the ftp server fine from my browser so I know the server is up and running correctly, also anonymous login to the server is allowed .</p>

34,719 | 34,720 | Include External Libraries in Packaged Python Application | <p>I have just picked up Python to develop a tool and I am so far really enjoying the language, however have one issue I am not entirely sure how to solve.</p>
<p>I am looking to use a few external libraries in my project, at the moment cherryPy and Cheetah however I am not sure how to package up my application so that these libraries are included. Coming from a .NET world the compiler used to do pretty much everything for me.</p>
<p>Have done a bit of googling but have not been able to find any solution, so I must be missing something fundamental. Is this something I need to configure distutils for? Do I need to copy the libs in to my application folder structure anywhere? Both?</p>

2,901,145 | 2,901,146 | voice classification api for android | <p>I want to develop an android application which interacts with the user using voice. I looked at google's speech to text API at <a href="http://developer.android.com/reference/android/speech/RecognizerIntent.html" rel="nofollow">http://developer.android.com/reference/android/speech/RecognizerIntent.html</a></p>
<p>I could not find anything which provides a classification service.
Recognition is much more difficult than classification.
In my usecase, my app will give user the options(eg: say left or right). So, instead of solving the harder of problem of what recognizing what the user said, I only need to decide whether he/she said left or right. I believe that the currrent state of the art in speech classification can solve the latter binary-classification problem with almost 99% accuracy.</p>
<p>Is their an API which is optimized for classifying voice into few(2-3) classes(words/phrases), rather than full blown recognition?</p>
<p>(I have significant Java/C++/machine learning experience, but no android experience)</p>
<p>(recognition, as described above can also be viewed as classification into infinitely many sentences ; hence it is a harder problem(2 vs countably-infinite classes))</p>
