Could you also post your settings.gradle?

Also did you add this to your MainApplication.java?

@Override
protected List<ReactPackage> getPackages() {
    return Arrays.<ReactPackage>asList(
        new MainReactPackage(),
        new RCTMGLPackage(),
    );
}

This is my settinngs.gradle

`
rootProject.name = 'SampleMap'

include ':app'
include ':mapbox-react-native-mapbox-gl'
project(':mapbox-react-native-mapbox-gl').projectDir = new File(rootProject.projectDir, '../node_modules/@mapbox/react-native-mapbox-gl/android/rctmgl')
`
