Answer 1

I was having this same issue with React Native 0.60.0 and none of above answers gave me a solution, so i fixed with this:

npm i jetifier
npx jetify

jetifier is an AndroidX transition tool in npm format, with a react-native compatible style.

If you use React Native modules with native Java code that isn't converted to AndroidX, and your app is AndroidX, you probably need this

so, in RN 0.60 you need AndroidX

Answer 2

• Open project use AndroidStudio3.3+

• Click module android[react-native-gesture-handler]
• Click top Refactor -> Migrate to AndroidX
• Done

Answer 3

Opened the project in android studio -> browse to the specified file in RNGestureHandler

remove this

import android.support.v4.util.Pools;

And add this

import androidx.core.util.Pools;
