A common (unfortunately, IMHO) way to do this is for your app to create a small hidden prefs db that uses a different creator id. Then whenever your app runs, it can check that db to see how often it has run before, when was the last time, whatever you want to store there. The problem with this method, and every strategy for limiting the number of times an app can run, is that it wastes valuable device memory and users get P---ed Off when they realize they have lost that space and don't know where it went or how to get it back. (Example Scenario: User installs 10 such apps, tries them out, then deletes them. Each leaves a 1K file behind. Now User has lost 10K and is not happy.) __________________________________________________ Do You Yahoo!? Yahoo!
