title: Full screen transparent activity (no title & status bar) doesn't work.... why?
body: <p>I'm making a custom lock screen.</p>
  
  <p>The lock screen is an activity which I launch by the time the screen goes off.</p>
  
  <p>However, I can't make the activity be both transparent &amp; fullscreen. </p>
  
  <p>The Status bar keeps showing.</p>
  
  <p>Here's what I do in the manifest:</p>
  
  <pre><code>&lt;activity android:name=".activities.LockScreenActivity"  android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen"/&gt;
  </code></pre>
  
  <p>I'm also adding these extras in activit's onCreate:</p>
  
  <pre><code>    requestWindowFeature(Window.FEATURE_NO_TITLE);
      setContentView(R.layout.lock_screen);
      getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
  </code></pre>
  
  <p>But it can't seem to work :|</p>
  
  <p>why?</p>
