it repeated this failure to recreate successfull working react-native-maps

react – 16.3.1
react-native – 0.55.4
react-native-maps – 0.21.0

step 1
i created app like this
$react-native init tank1

step 2
I followed installation from
https://github.com/react-community/react-native-maps/blob/master/docs/installation.md

step 3
follow installation from
https://itnext.io/install-react-native-maps-with-gradle-3-on-android-44f91a70a395

step 4
in MainApplication.java
use without @Override

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

Note :
I had doub’t about synatx@import GoogleMaps; in AppDelegete.m but this too works fine
