Why Google Maps is showing empty screen in my Android App?

Question

I have Google Maps in my Android App. I added it by selecting new Google Maps Activity & pasting the key in Android Studio. It worked fine in my Android phone (Lenovo K5

Answer 1

Given the fact that your app works on Lenovo, the most probable cause is that your Coolpad phone doesn't have Google Play services which are mandatory when you use most of Google's products. (here you can find more details about this problem for Coolpad 8675). Unfortunately, you can't fix this as a developer. If an user really wants to user your app and doesn't have the Play Services you can show an error telling what's the problem and that they should install them before using your app. From this point, they should be able to find enough tutorials on how to do this thing.
