If you use ADT and Eclipse:

    String version = getPackageManager().getPackageInfo(getPackageName(), 0).versionName;

If you use Gradle, there is an easier way, since it puts the data into BuildConfig for you:

    String version = BuildConfig.VERSION_NAME;

Konstantin&#39;s answer (above) is correct, but for what it&#39;s worth I found that I got a compiler error if I did not catch a `NameNotFoundException` , as follows:

    import android.content.pm.PackageManager.NameNotFoundException;
    try {
        String version = getPackageManager().getPackageInfo(getPackageName(), 0).versionName;
    } catch (NameNotFoundException e) {
        Log.e(&quot;tag&quot;, e.getMessage());
    }




I have been using the following code (with jQuery v1.4.2) to set the &#39;selected&#39; attribute of a select list based on  its &#39;text&#39; description rather than its &#39;value&#39;:

    $(&quot;#my-Select option[text=&quot; + myText +&quot;]&quot;).attr(&quot;selected&quot;,&quot;selected&quot;) ;

This code worked fine, until I noticed one select list on which it failed, depending on the text that was being matched. After some hair-pulling I realized that it was failing only in cases where the text was a single word (no spaces, no non-alpha characters). (All of my previous uses of this code had worked fine with select lists comprised solely of multi-word chemical names.)

For example, within the one select list, it worked fine with:  
pharbitic acid  
25-D-spirosta-3,5-diene  
pogostol (#Pogostemon#)   

It failed with:  
glucose  
adenine

I have tried any way I could think of to surround the text variable with quotes (both single and double) to no avail. (But why should a single word need quotes when a two word phrase does not?)

I have tried hard coding the text in there and had the same result.

This works:

    $(&quot;#constituent option[text=#a#-allocryptopine]&quot;).attr(&#39;selected&#39;, &#39;selected&#39;);
      
This works:

    $(&quot;#constituent option[text=5-O-methylrisanrinol]&quot;).attr(&#39;selected&#39;, &#39;selected&#39;);

This **did not work**: 
 
    $(&quot;#constituent option[text=adenine]&quot;).attr(&#39;selected&#39;, &#39;selected&#39;);

I tried hard coding quotes. This **did not work**:

    $(&quot;#constituent option[text=&#39;glucose&#39;]&quot;).attr(&#39;selected&#39;, &#39;selected&#39;);

I could not get hard coded quotes (single or double) to work with _any_ text at all.

It&#39;s worth noting that quotes are acceptable when using the &#39;value&#39; attribute. E.g., both of these work fine:

    $(&quot;#constituent option[value=&#39;3&#39;]&quot;).attr(&#39;selected&#39;, &#39;selected&#39;);
    
    $(&quot;#constituent option[value=3]&quot;).attr(&#39;selected&#39;, &#39;selected&#39;);

Below is some code to demonstrate the problem. Two select lists, the first of which is comprised of simple words, the second of two word phrases. When the page loads it tries to set the value of each select list. The jQuery code works for the second list but not the first. (I tried putting a space in &#39;monkey&#39; to get &#39;mon key&#39; and it worked!)
 
A working demo of the code below is &lt;a href=&quot;http://snubian.com/test/select.html&quot;&gt;here&lt;/a&gt;.

I would greatly appreciate any insight into what I am doing wrong here. Or even an alternative selector syntax for using the &lt;option&gt; &#39;text&#39; attribute. Thanks in advance to all who have the time to assist.

shared_ptr: horrible speed

The `AndroidManifest.xml` contains the version name of the application, something like

    android:versionName=&quot;1.0&quot;

Now the question - is it somehow possible to access this version name in the source code, so that I can display it for example in an About `Dialog`?

This is a two-part question about adding a third-party library (JAR) to an Android project in Eclipse.

The first part of the question is, when I try to add a third-party JAR (library) to my Android project I first get the problem of

&gt; Error parsing XML: unbound prefix

because I&#39;m trying to use a class from that JAR (and need the prefix somehow defined). What&#39;s going on?

Second, (after fixing that--the answer is given below), my application doesn&#39;t work on Android and I discover via the debugger (LogCat) that the class I&#39;m attempting to consume doesn&#39;t exist.

&gt; Caused by:
&gt; java.lang.ClassNotFoundException:
&gt; com.github.droidfu.widgets.WebImageView...

Why, when I get no compilation or linker error in Eclipse, does it have this problem on the emulator?

These two questions are rhetorical for I&#39;m going to answer them myself below. Other posts in this forum creep up to the problem and elsewhere there is discussion, but I feel that I can be more explicitly helpful for the next guy to come along.

When I load an image from the media gallery into a Bitmap, everything is working fine, except that pictures that were shot with the camera while holding the phone vertically, are rotated so that I always get a horizontal picture even though it appears vertical in the gallery.

I applied a custom font to a `TextView`, but it doesn&#39;t seems to change the typeface.

Here is my code:

        Typeface myTypeface = Typeface.createFromAsset(getAssets(), &quot;fonts/myFont.ttf&quot;);
        TextView myTextView = (TextView)findViewById(R.id.myTextView);
        myTextView.setTypeface(myTypeface);

Can anyone please get me out of this issue?


Android - Using Custom Font

I have a custom file type/extension that I want to associate my app with.

As far as I know, the data element is made for this purpose, but I can&#39;t get it working.
http://developer.android.com/guide/topics/manifest/data-element.html
According to the docs, and a lot of forum posts, it should work like this:

    &lt;intent-filter&gt;
    	&lt;action android:name=&quot;android.intent.action.MAIN&quot; /&gt;
    	&lt;category android:name=&quot;android.intent.category.DEFAULT&quot; /&gt;
    	&lt;category android:name=&quot;android.intent.category.BROWSABLE&quot; /&gt;
    	&lt;data android:mimeType=&quot;application/pdf&quot; /&gt;
    &lt;/intent-filter&gt;

Well, it does not work. What did I do wrong? I simply want to declare my own file type.

Android intent filter: associate app with file extension

I have written a service with a remote interface and installed it on my PC&#39;s Eclipse AVD. I have a client test harness which starts and invokes methods in the service. Initially I had the service installed by a control class and activity, which I have now removed, so that the manifest for the service looks like:

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;manifest
    xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
    package=&quot;com.myname.gridservice&quot;
    android:versionCode=&quot;1&quot;
    android:versionName=&quot;1.0&quot;&gt;
    &lt;application
        android:icon=&quot;@drawable/icon&quot;
        android:label=&quot;@string/app_name&quot;
        android:debuggable=&quot;true&quot;&gt;
        &lt;service
            android:enabled=&quot;true&quot;
            android:debuggable=&quot;true&quot;
            android:name=&quot;OverlayService&quot;&gt;
            &lt;intent-filter&gt;
                &lt;action android:name=&quot;com.myname.OverlayService.SERVICE&quot;/&gt;
                &lt;action	android:name=&quot;com.myname.gridservice.IRemoteInterface&quot; /&gt;
            &lt;/intent-filter&gt;
        &lt;/service&gt;
     &lt;/application&gt;  
    &lt;/manifest&gt;   
 

so there&#39;s no activity tag.  

When I launch it from the debug icon in Eclipse, the console tells me that it&#39;s installing the apk (which it is), but it does not appear as a debug thread and breakpoints aren&#39;t triggered, although the service&#39;s behaviour is OK as far as the client sees it. If I wrap the service tag in an activity tag which has an associated class and launch that, then I can debug it.

Is it possible to debug the service without wrapping it in an activity?

Debugging a service

Is it possible to view `Androidmanifest.xml` file?

I just changed the extension of the `apk` file to `zip`. This `zip` file contains the `Androidmanifest.xml` file. But I am unable view the contents of `Androidmanifest.xml`. It is fully encrypted.

I&#39;ve written a wrapper on top of Log.java that is provided by android. My Class will add some other application level features in Logs.

Now the things is that I want to check from the code whether &quot;debuggable&quot; is set to &#39;true&#39; or &#39;false&#39; in androidManifest.xml file. 

Can I do that? If yes, how?

Getting &quot;debuggable&quot; value of androidManifest from code?

I&#39;ve read through several posts about using this, but must be missing something as it&#39;s not working for me. My activity A has launchmode=&quot;singleTop&quot; in the manifest. It starts activity B, with launchmode=&quot;singleInstance&quot;. Activity B opens a browser and receives and intent back, which is why it&#39;s singleInstance. I&#39;m trying to override the back button so that the user is sent back to the activity A, and can then press Back to leave the activity, rather than back to activity B again.

    // activity B
    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event)  {
     if (android.os.Build.VERSION.SDK_INT &lt; android.os.Build.VERSION_CODES.ECLAIR
      &amp;&amp; keyCode == KeyEvent.KEYCODE_BACK
      &amp;&amp; event.getRepeatCount() == 0) onBackPressed();
     return super.onKeyDown(keyCode, event);
    }
    @Override
    public void onBackPressed() {
     startActivity(new Intent(this, UI.class)
     .setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK));
     return;
    }

After returning from the browser, the stack is...
A,B,Browser,B

I expect this code to change the stack to...
A
... so that pressing back once more takes the user back to the Home Screen.

Instead it seems to change the stack to...
A,B,Browser,B,A
...as though those flags aren&#39;t there.

I tried calling finish() in activity B after startActivity, but then the back button takes me back to the browser again!

What am I missing?
