This React Native project demonstrates crashing behavior on a Nexus 9 (and presumably other 64bit ARM devices).

The only difference between it and a vanilla React Native project is that I've added compile 'io.realm:realm-android:0.82.2' to the android/app/build.gradle file.

The reason it fails is likely due to the fact that Android can't mix 32 and 64bit native libraries, and realm-android contains a 64bit native library.

Run on a Nexus 9, the stacktrace is as follows:
