Possible Duplicate of this question. Try running this command from root directory of your project.

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

I encountered the same problem.

I resolve this, by deleting the dependency in android\settings.gradle file. That not specified in the build.gradle file.

This fix my problem. Hope this helps you.
