Starting with Android 3.1 all applications, upon installation, are placed in a stopped state. While in stopped state, the application will not run for any reason, except by a manual launch of an activity, or an explicit intent that addresses an activity ,service or broadcast.
When writing system app that installs APKs directly, please take into account that the newly installed APP won't receive any broadcasts until moved into a non stopped state.
An easy way to to activate an app is to sent a explicit broadcast to this app. as most apps implement
INSTALL_REFERRER, we can use it as a hooking point
Scan the manifest of the installed app, and send an explicit broadcast to to each receiver:
Intent intent = new Intent(); intent.addFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES); intent.setComponent(new ComponentName(packageName, fullClassName)); sendBroadcast(intent);
