in android nothing displayed
<p>I am doing a application that has database coding and some classes. I put Log.e() after and before the <code>setContentView(R.layout.main);</code> in main activity but no log value printed in Logcat and no design applied for the main activity. </p>

<p>my logcat prints:</p>

<blockquote>
