How do I store data on the device so even when the application terminates, the data can be loaded again once the application is run once again. Is it just as simple as storing a file on the SD card? Or is there some other way? Basically, I'm looking to offer the option to "trial" my program, but only for a certain number of times, so I want to keep track how many times my runs a certain feature even if the program isn't purchased and has a license. All I really need is to store a number of how many times it has run.
