[android-developers] Broadcast Receiver to listen when any app launch?

I want to be notified when any app launch like Calculator, Email etc,

so I tried below code

#Attempt 1

<receiver android:name=".ApplicationLaunchReceiver"> 

    <intent-filter> 

        <action android:name="android.intent.action.MAIN" /> 

        <category android:name="android.intent.category.LAUNCHER" />

    </intent-filter> 

</receiver>

but this code didn't work. then I tried one more code,

#Attempt 2

   

<receiver android:name=".CatchBroadcastReceiver" >

    <intent-filter >

        <action android:name="android.intent.action.PACKAGE_ADDED"/>

<data android:scheme="package" android:path="com.test"/>

    </intent-filter> 

</receiver>

but this code also didn't work.  Please let me know what I am doing wrong.
