" > Task :app:transformClassesWithDexBuilderForDebug FAILED

Can anyone help me about this Please

Answer 1

just do this :

in main project folder ,in terminal type

cd android

then type this

./gradlew clean

or try this, run this code in your project folder

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

and after that

cd android && ./gradlew clean && cd .. && react-native run-android

then build your app again
