I would do the same. Get the android ID like this:
String android_id = android.provider.Settings.System.getString (this.getContentResolver(), android.provider.Settings.System.ANDROID_ID); Then send it to your back-end and query the number of times you've made the same call or the date you firstly made a call against the unique ID. Hope it helps!
