Java Android GCM getting collapse_key

Question

I just read that it is possible to group some messages to a collapse_key. Is it possible to get this collapse_key in the IntentService? I would need it for identification reasons.

Answer 1

Do it like this in your IntentService:

intent.getExtras().getString("collapse_key");

Answer 2

You mean with an Intent? Try this:

String collapseKey = intent.getStringExtra("collapse_key");
