  • Please edit the question to limit it to a specific problem with enough detail to identify an adequate answer. – Community Sep 25 '22 at 19:50
  • Removed tag `android-studio` as that tag is used for questions/issues regarding the Android Studio product. Your question has nothing to do with Android Studio. – David Wasser Sep 25 '22 at 21:49

Make your app must login to use. Server shouldnt respond to any invalid payments etc. Fully safe.

95+% Safe Method:

Server must not return anything like any sort of data.
Means app is useless without server.
And server is not accessible without login
