How to set canOverrideExistingModule=true in React Native?

Issue

I build an android app using React Native,build got success but when i run app in my AVD it show up a error:

How can I fix this issue?

Solution

What you can try is first remove the duplicate declarations in method getPackages() of your MainApplication.java file.

If you're using Android Studio this file is in app > java otherwise you can find it in android/app/src/main/java/com/yourAppName/yourProjectName/MainApplication.java.

Then try again react-native run-android
