    compile project(':react-native-splash-screen')
}

import com.cboy.rn.splashscreen.SplashScreenReactPackage;
public class MainApplication extends Application implements ReactApplication {

    private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {

            return BuildConfig.DEBUG;
        }

        @Override

            return Arrays.<ReactPackage>asList(
                    new MainReactPackage(),
            new SplashScreenReactPackage()  //here
            );
