How identify instance of an app
i'm creating an app, and I need to have a unique identifier for each instance of the app.
I like to know what is the best way to create this identifier and how to store it in a way that in case the user wipes the application data the handle remains stored in the device.
after trying many ways to solve this problem, I found this solution:
JStringToString(TJSettings_Secure.JavaClass.getString( SharedActivity.getContentResolver, TJSettings_Secure.JavaClass.ANDROID_ID));
