Answer 1

You need remove generated resources/drawable and generate again.

rm -rf android/app/src/main/res/drawable-*
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 compile android again react-native run-android

Answer 2

[0.57] Ugly workaround

If you don't want to rollback the react-native version, you can just rollback the react.gradle to the last working version. That worked for me.

Copy the git code to node_modules/react-native/react.gradle

https://github.com/facebook/react-native/blob/2d9e2f30e17b8e79f2c44ef533ecdd550671304c/react.gradle

If the problem persists, try to remove the if (isAndroidLibrary) on doLast.
