Answer 1

After researching on google and find no other similar solution, i then try to delete the duplicate files mention in the error and it works! These are the 2 files i have removed:

1. android\app\src\main\res\raw\app.json
2. android\app\build\generated\res\react\release\raw\app.json

After removing these 2 files, i then run:

cd android
./gradlew assembleRelease

Then it shows me build successful :)

You need to clean the duplicates resources.

use the following commands

rm -rf ./android/app/src/main/res/drawable-*
rm -rf ./android/app/src/main/res/raw
