title: Activity doesn't show in full screen
body: <p>I defined a new Activity on my project and I have some trouble with fullScreen.</p>
  
  <p>I defined in the manifest file like this:</p>
  
  <pre><code>&lt;activity android:name=".Test"
       android:launchMode="singleInstance" android:screenOrientation="portrait"
       android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
       .............
  &gt;
  </code></pre>
  
  <p>If I start the activity from another activity, I got the desired full screen. The problem is when I start this activity from a BroadcastReceiver - I need to open this activity inside a BroadcastReceiver something like this:</p>
  
  <pre><code>public void onReceive(Context context, Intent intent) {
       Intent test = new Intent(context, Test.class);
       test.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
       context.startActivity(test);
  }
  </code></pre>
  
  <p>I tried like this too:</p>
  
  <pre><code>protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
  
      requestWindowFeature(Window.FEATURE_NO_TITLE);
      getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
         WindowManager.LayoutParams.FLAG_FULLSCREEN);
  
      setContentView(R.layout.test);
  }
  </code></pre>
  
  <p>and no full screen if the activity starts from my BroadcastReciever.</p>
  
  <p>Why I don't get full screen on this case? There is any way to request full screen after the Activity is created and visible?</p>
