Any one facing react native build issue? I am trying to generate debug build but its crashing when the app is launched . The exception has no useful information. I was facing the same issue with
sudo react-native run-android
But that got resolved after upgrading RN from 0.48 to 0.55(latest Stable Version). But the crash remain same for the apk generated using
sudo gradlew assembleDebug
The crash is similar to https://github.com/facebook/react-native/issues/16745
please see screenshot
Solution: Generating React Native Android Release and Debug Builds
