It seems starting from Android 4.0 you cannot do anything after install, until the user explicitly launches your app. As of Android 4.0 you don't receive any broadcasts unless the user starts your app once manually. The app is in deactivated state directly after install to stop apps you just downloaded but never used from using up system resources. No code in your app is started, no receiver or service registered etc. Once activated through user interaction it works like before.
