Thread returns error in android 4.0.3 version

Question

I have a question that I have a splash screen in my android app in which I am using thread to wait for 8 seconds, it is running fine in 1.6,2.1,2.2,2.3.3, 3.0, 3.1 but returns error when I want to run the same in 4.0.3 version of android, I don't know why? Please suggest me the right solution for the same. Below I mentioned error stack and my code also.

        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        splash =  new Thread(){
            @Override
            public void run(){
                try {

                    synchronized(this){
                    // Wait given period of time or exit on touch
                        wait(4000);
                        Intent intent = new Intent(SplashScreen.this,HomeActivity.class);
                        startActivity(intent);
                        finish();
                    }
                }
                catch(InterruptedException ex){                    
                }

                finish();


                stop();                    
            }
        };


        splash.start();   
    }
}

Everybody's already said where the exception is coming from (Thread.stop()), so I'll leave that alone...

By far, the easiest method is to not create a Thread for this purpose at all; even an AsyncTask is over-doing it. This is what the Handler was created for (or even CountDownTimer, but Handler is cleaner, IMO).

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Handler handler = new Handler();
    Runnable action = new Runnable(){
        @Override
        public void run(){
            Intent intent = new Intent(SplashScreen.this,HomeActivity.class);
            startActivity(intent);
            finish();
        }
    };

    handler.postDelayed(action, 8000);  
}

The Handler will even run the action on the main thread for you, where that code should pretty much be called anyway.

Thread.stop is deprecated method which is the reason you are getting exception. It will work on lower versions with a warning. Try using AsyncTask instead of threads. They are much safer
