Question

What I want is 5 minutes after I open the application do a specific work.

I am not sure what I suppose to do.Should I create an AsyncTask in onCreate method of my main activity or a thread? Or should i do something completely different?

Answer 1

You could use a Handler :

 new Handler().postDelayed(new Runnable() { public void run() {
           //your delayed action here, on UI Thread if needed
      }
   }, 1000 * 60 * 5 );
