When i download and install Tower DroidPlanner 3 from google play, it shows the map normally. However when i build this project in android studio and copy the .apk file into my mobile (or connect via USB) and run, it can’t show map in the main screen. I try to reinstall and enable GPS but it still doesn’t work.
Hope for helping. Thank you.
Update Google Maps for Android API key in AndroidManifest.xml then rebuild it.
