Android: Splash Screen re-opens app to second page even if app is quit during splash screen

问题

Ok, so i created a very simple splash screen using this tutorial:

http://p-xr.com/android-tutorial-how-to-make-a-basic-splash-screen/

The problem is that if the user hits the home button or the back button to exit the app during the splash screens duration then the app will re-open to the second screen after the splash screen would have been done if the user did no exit.

My code is pretty much that of the tutorial. any help?

Thanks

I have modified the code to make use of the lifecycle methods better. enjoyed changing it. :)

   public class SplashScreen extends Activity {

        protected int _splashTime = 5000; 

        private Thread splashTread;

        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.splash);


            final SplashScreen sPlashScreen = this; 

            // thread for displaying the SplashScreen
            splashTread = new Thread() {
                @Override
                public void run() {
                    try {                   
                        synchronized(this){
                            wait(_splashTime);
                        }

                    } catch(InterruptedException e) {} 
                    finally {

                        if(!isFinishing()) // This pretty useful boolean val tells if 
 //user has pressed the back button. very useful.
                        {Intent i = new Intent(SplashScreen.this, Main.class);

                        startActivity(i);
                         finish();
                         }


                        stop();
                    }
                }
            };

            splashTread.start();
        }
        @Override
        public boolean onTouchEvent(MotionEvent event) {


            if (event.getAction() == MotionEvent.ACTION_DOWN) {
                Toast.makeText(this,"exec---",Toast.LENGTH_LONG).show();
                synchronized(splashTread){
                    splashTread.notifyAll();
                }
            }
            return true;
        }
        @Override
        protected void onPause() {

            super.onPause();

            if(splashTread.getState()==Thread.State.TIMED_WAITING){
                //Thread is still waiting and Activity is paused. Means user has pressed Home. Bail out
                finish();
            }

        }
    }

My point of view is that the use of Splash Screen is not frequent but maybe needed. If you are doing heavy work behind the screen( such as games).
