The framework code that Piren posted a link to above (below?) accesses the Intent object before calling the receiver's onReceive:
http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.2.2_r1/android/app/ActivityThread.java#2350 Line 2350: data.intent.setExtrasClassLoader(cl); This code will crash inside the framework if the intent is null. However, this is a specific version of *stock* Android... Other versions, including manufacturer specific or custom ROMs may, in theory, be different. Weird things do happen though, when you have an app in Play and it gets installed on a fair number of different devices. I recall one crash report in Play where the framework was complaining about not being able to find the application's .apk while instantiating the Application subclass object (or something equally absurd). Over time, you learn to not worry about these too much. -- K 2013/7/15 Palmer Eldritch <the.u...@gmail.com>: > Glad you agree with each other > > Have you thought that this could be a way of delving a bit deeper into the > framework ?
