Answer 1

The way above with

ChildActivity childActivity = (ChildActivity) getLocalActivityManager().getActivity("Tab 1");
childActivity.onNewIntent(intent);

is not very nice. Instead of invoking your activity method directly (it can be null!!!) better do it this way:

intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
intent.putExtra(AlbumBrowser.INTENT_EXTRA_FILTER, mediaTitle);
getLocalActivityManager().startActivity("activityIdHere", intent);
