How to make app wait and then start activity or go back?

I want my activity to show a screen for 3 seconds, then go back to previous screen. But when i use

protected void onCreate(Bundle savedInstanceState) {
        TextView tvResult = (TextView)findViewById(
            Intent i = new Intent(this,myActivity.class);

But unfortunately, this does not work. This doesent show the activity waits 3 seconds and goes back. However, i want it to show its contents before going back. How can i do it ?


You should remove this Thread.sleep(3000); which block the ui thread. You should never block the ui thred. You can use a Handler postDelayed with a delay and then startActivtiy.

Handler handler = new Handler();
handler.postDelayed(new Runnable(){
  public void run(){
   // do something
 }, 3000);

To go back to previous Activity you can call finish().

Also if you need to go back to the previous activity for 3 seconds why do you need

Intent i = new Intent(this,myActivity.class);

Calling finish() will do the job
