Android App crashing due to thread

Question

I'm trying to make my first activity sleep for 5 seconds and then start a new activity but when I'm testing the application. The app is crashing. Here is my logcat

06-03 12:40:28.915: E/AndroidRuntime(1480):     at android.app.Instrumentation.checkStartActivityResult(Instrumentation.java:1618)
06-03 12:40:28.915: E/AndroidRuntime(1480):     at android.app.Instrumentation.execStartActivity(Instrumentation.java:1417)
06-03 12:40:32.655: I/Choreographer(1480): Skipped 56 frames!  The application may be doing too much work on its main thread.
06-03 12:40:33.675: I/Process(1480): Sending signal. PID: 1480 SIG: 9

And below is my code.

           Thread timer = new Thread(){
    public void run(){
        try{
            sleep(5000);
        Intent openStartingPoint = new Intent(MainActivity.this, Menu.class);
            startActivity(openStartingPoint);
            finish();
        }   
        catch(InterruptedException e){

            e.printStackTrace();        

        }


    }


    };

timer.start();

}
