Any idea?

a couple of things. 1. you should spend some time with question editor. there are many options to make your question more readable. 2. its just not clear what you are trying to solve here. — Jay, Sep 27 '20 at 04:30

Make sure tha you have the following :

MainActivity.java:

import com.facebook.react.ReactActivityDelegate;
import com.facebook.react.ReactRootView;
import com.swmansion.gesturehandler.react.RNGestureHandlerEnabledRootView;

And add this inside the MainActivity class, just after protected String

getMainComponentName() function
@Override
protected ReactActivityDelegate createReactActivityDelegate() {
return new ReactActivityDelegate(this, getMainComponentName()) {
@Override
protected ReactRootView createRootView() {
return new RNGestureHandlerEnabledRootView(MainActivity.this);
}
};
}

Then do the following:

cd android
gradlew clean
cd ..

Finally re-run the app: react-native run-android
