Just posting an answer so that people who visit this page get the solution.

You need to use putExtra(ID_KEY,id) when you create your Intent for starting your application, and in your onCreate() method you can use getIntent().getExtras().getInt(ID_KEY); to retrieve your passed id integer.

The passed extra could be anything, a boolean, String etc.
