i'm pretty sure it's impossible to guarantee something like that... i don't think part of their new programmer orientation is "if you ever touch the code that runs BroadcastReceiver.onReceive...never send a null intent".
Either way, at least on android 4.2.2_r1, it seems like it's impossible to get a null intent. feel free to verify this is true for all previous versions as well (and don't forget to keep checking this method every time they make a new build). http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.2.2_r1/android/app/ActivityThread.java#2335 On Thursday, July 11, 2013 4:09:27 PM UTC+3, Palmer Eldritch wrote: > > That's nice advice - but in this case I think one should have a guarantee > > Does it make sense to receive a null intent ?
