Apps Which Android Intent is broadcasted by the system whenever a app is launched from Homescreen?

[yafy]

Hi friends,

I am developing an application contains a BroadcastReceiver which listens for event from system when any app(like Contacts, Gallery, Messaging,..) is launched from home screen or App screen.

I tried listening to the intents,
<actionandroid:name="android.intent.action.MAIN"></action>
<categoryandroid:name="android.intent.category.LAUNCHER">

But Im not catching it(i mean onRecieve() is not getting called).

My question is, Which Android Intent is broadcasted by the system whenever a app(like Contacts, Gallery, Messaging,..) is launched from Homescreen(So that i can linten to it)?

or is it to possible receive that Intent ?

Thanks in advance
