My Android react native is working fine for debug builds, but after building the signed release apk with: cd android && ./gradlew assembleRelease then it always crashes on startup. The file size of the APK looks pretty similar to the debug one (not a huge difference). Here is the error from logcat. (I have checked the other stackoverflow issues on release ask problems but could not find a solution. I have also tried 'gradle clean' build).
React-native version 0.44
