由于线程导致Android App崩溃

Question

我正在尝试让我的第一个活动睡眠5秒，然后开始新的活动，但是当我正在测试应用程序时。该应用程序正在崩溃。 这是我的logcat

06-03 12:40:28.915: E/AndroidRuntime(1480):     at android.app.Instrumentation.checkStartActivityResult(Instrumentation.java:1618)

           Thread timer = new Thread(){
    public void run(){
        try{

            startActivity(openStartingPoint);
            finish();
        }   
        catch(InterruptedException e){

            e.printStackTrace();

             Intent openStartingPoint = new Intent(MainActivity.this, Menu.class);
