Apps White screen.

[hfdjw]

When I start the app on my emulator i get only white screen and nothing other.
Where is the problem?
[HIGH]package com.example.soslocksmith;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
System.out.println("fgew");
setContentView(R.layout.activity_main);
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
}

setContentView(R.layout.calllayout);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}

}

activity_main.xml:

xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="visible"
tools:context=".MainActivity" >

<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="176dp"
android:text="Large Text"
android:textAppearance="?android:attr/textAppearanceLarge" />

</RelativeLayout>[/HIGH]

on the screen you see the layout from calllayout.xml. not activity_main.xml. The first setContentView has no effect. Also the sleep is pointless here. The view is shown after onCreate and it is the one from the last setContentView call.
