Question

I would like to trigger showing a dialog X seconds after something happens in an activity (resumed, button clicked, etc.)

• What are my options? (e.g. Thread, AsyncTask, Handler)
• Are there special things to note for these options? e.g. do I need to check if the activity is still active?

Answer 1

use handler.postDelayed(runnable, delayedms);

this is one of the methods, you can also use AlaramManager.

For AlaramManager your activity need not be active. and handler it should be.
