Is there any problem with this code?

It produce the stopped unexpectedly problem when I push the search button.

public class beautiful extends Activity {
    ImageView radar;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
      this.requestWindowFeature(Window.FEATURE_NO_TITLE);
      this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.beautiful);

    radar = (ImageView) findViewById(R.id.radar);
    Button search = (Button) findViewById(R.id.magnifier);
    ImageView text = (ImageView) findViewById(R.id.text);
    MediaPlayer siren = MediaPlayer.create(this, R.raw.siren);

    search.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            Thread counter = new Thread(new Runnable(){

                @Override
                public void run() {
                    // TODO Auto-generated method stub
                    try{
                        Thread.sleep(2000);
                        radar.setImageResource(R.drawable.radar_new_full);
                        Thread.sleep(3000);
                        radar.setImageResource(R.drawable.radar_new_50);
                        Thread.sleep(2000);
                        radar.setImageResource(R.drawable.radar_new_found);
                    } catch (InterruptedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    finally{

                    }
                }

            });
            counter.start();
        }
    });
}

Here are the LogCat warnings:

You can try this:

public void onCreate(Bundle icicle) {
super.onCreate(icicle);
//do sth...
}

Put some print statements here and there or breakpoints, whichever you prefer. Trace down which line is the one which causes the error, try putting try-catch statements around it to have a clear idea of what the error is - then it would be easier to solve the error (Shortly debug)

Try to remove @Override above the public void run().
