Program type already present: com.mapbox.rctmgl.BuildConfig

Describe the bug Hello 😄 I’m trying to build a project that uses react-native-mapbox-gl. Previously I have done all the steps on https://github.com/react-native-mapbox-gl/maps/blob/master/android/install.md. But this error appears on the app build.

* What went wrong:
Execution failed for task ':app:transformClassesWithMultidexlistForDevRelease'.
> com.android.build.api.transform.TransformException: Error while generating the main dex list:
  Error while merging dex archives: 
  Program type already present: com.mapbox.rctmgl.BuildConfig

}

@nan140114 do you have anything mapbox related in your gradle?! We need to clean our docs up. With autolinking and 0.60+ you don’t need anything in gradle

Greetings to both of you. Yes, I followed the guide on the docs to link manually the library on the android app. Following the @mfasekas advice, I removed all the Gradle and Java (MainApplication.java) set up and it worked. Thank you.

Note: I’m going to meet up with the development team to consider using the last release.

Thank you for time again!
