Execution failed for task ':app:mergeReleaseResources' after generating bundle files

I have an issue where the release APK build fails.

Background: I had the error: Unable to load script from assets index.android.bundle

The solution I found for that issue was to: 1. (in project directory) mkdir android/app/src/main/assets 2.react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

But then I cannot build the release APK file successfully. 

Caused by: org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:mergeReleaseResources'

I expect the release APK to build successfully since everything else builds successfully (running the app on emulator and physical device)

Maybe the way I did it will work for you.

  1. Clean Project
  2. Rebuild project
  3. Sync project with gradle file

The solution for me was to delete all the drawable folders after running the command: 

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

It causes because of duplicate resource creation. So, remove all duplicate resources from directory-

/android/app/src/main/res/drawable-

then run the release command. Hope, it will build the production .apk successfully.
