> I ran into problems putting up a free and paid version of the same app on the Android market This is one of the most aggravating issues I have with the Android market at the moment. Every app that has a free version handles it differently: Some you buy a key and enter it (which means purchasing out of band), some use the Android Market micropayment system (so it often isn't clear you have to pay for the app at all), some use a free version and full version of the app (so if I play the first 15 levels in the demo, I have to play them all through again when I buy the game). C'mon, Google. Pretty common use-case here.
