Answer 1

Here is the simple solution :

1. Delete build inside android/app folder
2. Delete build inside android folder
3. run rm -rf $HOME/.gradle/caches/
4. Open build.gradle --> android/app/build.gradle
5. comment this line

//apply from: "../../node_modules/react-native/react.gradle"

6. Delete index.android.bundle file from assets folder and re-create using 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

7. run react-native run-android Or run react-native run-android --variant=release

Happy Coding..
