I developed a paid app for Android and would like to develop a demo of it. The demo application to run x number of times and then give a message to purchase the full application.
I tried using both Google in: http://developer.android.com/guide/publishing/licensing.html, but it still fails.
Does anyone have a walkthrough for this?
You could increment instances in a db or a file. The db and text file would be easy to crack but using a binary file will be more robust.
