Same problem.
RNGestureHandlerEvent.java:3: error: package android.support.v4.util does not exist
import android.support.v4.util.Pools;
you should use react-native 0.59.10, this project needs to migrate to androidX, now it doesn't work with react-native 0.60

As React Native 0.60.0 implements autolink, you need unlink native dependencies previously linked. Documentation:
Autolinking is a replacement for react-native link. If you have been using React Native before version 0.60, please unlink native dependencies if you have any from a previous install.
And for AndroidX at now you can use this workaround (You can found several PRs about it, waiting to be merged).
This issue is stale and AndroidX support has been already resolved. I'll close
