@YouJZ I'm not quite sure where to start with this one, especially since it looks like you're using an obfuscator which causes your method names to become symbols: void vy.֏

Are you able to reproduce this easily on a local device?

@samtstern This may be the same crash, without obfuscation. I got it during a stress test. Nexus 6, Android 7

@artakka thanks for that stack trace! Will be very useful.

So this is still happening to Nexus 6 devices on Nougat (7.1.1). Did anyone determine what the actual cause of this is? I can't seem to figure out where the null comes from since the fragment / activities being used shouldn't be null when invoking the call.
