title: largeHeap=true manifest tag not working?
body: <p>I´m developing a very memory-consuming app and want to use the largeHeap-Tag, which should give the application a bit more memory. Whatever I set this tag in AndroidManifest.xml to, it makes no difference to the actual memory I´ve been given. I´m reading out my max memory like this:</p>
  
  <pre><code>Log.v("Utils","Max Mem in MB:"+(Runtime.getRuntime().maxMemory()/1024/1024));
  </code></pre>
  
  <p>My manifest looks quite like this:
      
  
      
      
      
      </p>
  
  <pre><code>&lt;application android:label="@string/app_name" android:hardwareAccelerated="true" android:largeHeap="true" android:debuggable="true"&gt;
  
      &lt;activity android:name=".EntryActivity" android:label="@string/app_name"&gt;
          &lt;intent-filter&gt;
              &lt;action android:name="android.intent.action.MAIN" /&gt;
              &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
          &lt;/intent-filter&gt;
      &lt;/activity&gt;
  
  &lt;/application&gt;
  </code></pre>
  
  <p></p>
  
  <p>I´m running 3.1 in the emulator, output of my logging above is always 48MB. Can somebody help?</p>
