I don’t know why Google allow this app, because it will destroy free app.

Code your app to detect Internet connection, if unable to connect, then app shuts down. Make dialog prompt that says Internet connection is required.

Your a idea beast!! Problem comes @DriodGenie solves it with simple solutions.

Interesting lol, it does say that device is not connected to internet, but for some reason banner ads still load.
^Forcing users to have internet connection is like the best way to get negative reviews from angry people.
Besides it has only few downloads, how many people who installed this app also installed your app too? Exactly. if this had 50-100 mil then it would be something to worry about.
