This error roughly means that V4 has duplicates, just remove it. My mistake was because there was a V4.Jar in the AutoNavi map. I only deleted it. Under normal circumstances, there are conflict problems with such V4 or V7 packages:
1. You can run the script through buildDependence to accurately locate the problem,
2. If it is a dependency package conflict, use gradlew app:dependencies to query,
3. Finally, delete or de-duplicate. '
General strategies for general problems, the actual situation may be special, you have to try in various ways.
