For CodePush users

I was having this same problem but it didn't update my code just on a production build, it works fine in development.

Run the script:

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

After that, just do:

$ gradlew clean
$ react-native link
