Android Google Play FATAL EXCEPTION: mqt_native_modules with React-Native app on Release APK

Question

I'm struggling with my React Native app... It used to be deployed correctly with no errors before I updated many of the librairies I used in react-native, but now I have errors on Android & iOS.

It works fine with react-native run-android or with Android Studio, but my release APK does not pass Google Play tests.

Here is the Google Play logcat of the errors (partially) :

12-12 01:26:15.554: E/ReactNativeJS(13327): undefined is not an object (evaluating 'e.length') 12-12 01:26:15.556: I/Dpps(892): int DppsFeatureAd3::AdCalcCalibParams(struct DppsAdCfgParam &)():445 calib_a 14, calib_c 0, calib_d 0 12-12 01:26:15.558: E/ReactNativeJS(13327): Module AppRegistry is not a registered callable module (calling runApplication) 12-12 01:26:15.563: E/NetworkScheduler(11214): ignoring stale queue check message 12-12 01:26:15.563: E/NetworkScheduler(11214): --------- beginning of crash 12-12 01:26:15.564: E/AndroidRuntime(13327): FATAL EXCEPTION: mqt_native_modules 12-12 01:26:15.564: E/AndroidRuntime(13327): Process: com.mdef.mymatchup, PID: 13327

And here is my package.json :

}

I tried the answers of this issue but it did nothing. React-Native: Module AppRegistry is not a registered callable module

Did somebody already had the same problem ? It's been 3 days now and I don't know what to do anymore... I need help please !

Answer 1

Issue solved ! I have fixed my problem by downgrading React-Native from 0.51.0 to 0.49.5, and I have no more crash.
