Could not read path 'C:\MyApp\android\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values-az-rAZ'.

After generating the icons (which went well with ImageMagick legacy tools option), when running ‘react-native run-android’ I had the following error:

* What went wrong:
Could not read path 'C:\MyApp\android\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values-az-rAZ'.
> C:\MyApp\android\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values-az-rAZ

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

Hi @jbarradas ,

Have you tried to run:

cd android && gradlew clean
cd .. && react-native run-android

This can solve some problems on Android 😃

Or if this doesn’t work, you can try to remove the android/app/build folder altogether.

@ajaykumar97 other solution, delete folder android/app/build
