Description

I have been using react since, I published my app to playstore. So I got reports from the ANR/Crashes tab. This happen specifically on android 7 devices. and even on emulator.

Google play sometimes call it "tgkill" and have trace like this. I have so many crashes like 50 and up.

backtrace:

It's working as expected on Android 6 and 5 devices but not with 7 really. So I'm not sure what's happening inside.

react-native 0.43
react 16.0.0-alpha.6
Android emulator android 7.0
Real phone android : 7

As it happens, debugging individual crashes from a particular app is out of scope for the issue tracker. If you can distill this into a reproducible issue, we'd be happy to take a look.
