Answer 1

Make sure when you are launching the intent from the BroadcastReceiver you set the FLAG_ACTIVITY_SINGLE_TOP flag.

intent.addFlags (FLAG_ACTIVITY_SINGLE_TOP);

...


class HomeActivity extends Activity {
   ...
   @Override
   protected void onNewIntent(Intent intent) {
      Bundle extras = intent.getExtras();
   }
   ...
}

Just extending Cory Roy's answer you have to define "SingleTop" in AndroidManifest.xml too.

<activity
        android:name="MainActivity"            
        android:launchMode="singleTop"

It seems that extending android.support.v7.app.ActionBarActivity this method does not work...
