Got an idea for the deletion of add-on toons for you. Use a simple sqllite db on the device... when your main app finds/installs a toon, log a little date in the db (or some other way). Every time your main app starts up, just scan for any rows.. if any are there, check the timestamps... if it's after 2 days (maybe 3 or 4 to be safe), uninstall the .apks at that time.
HOWEVER, something occurred to me. Programmatically uninstalling .apks without the user knowing may not be advisable. Even tho the toon still works in the app for them, I would suspect most users, if they wanted to delete it (or otherwise look at stats on it), they would go thru the settings/manage applications route, and if they can't find it they may wonder what happened. Trying to explain to your end users that after a few days the .apk they bought/downloaded/installed will be uninstalled to "free up room", may be too much text for a simple toon purchase/install. Maybe not. Another thought..doubt it's possible.. and I still haven't paid for an app on android yet so not entirely sure how this works. I thought you'd set up a google checkout account.. being android and google and all. If that is the case, then like you said, it's likely that a user will have an account already.. or at least is more willing to submit their personal info setting up a gogle checkout account over some in-game form you provide. Now, I don't know how viable this is, but if the user already has a google checkout, is there a way to obtain their checkout info... in-app/game, without requiring them to fill anything out? This way, you could avoid the .apk market route, you earn the extra .30 per toon, you host it, you keep stats on downloads, which toons are more popular than others, etc. Tons of stuff you can control from this aspect of it. If a user already set up a google checkout account, how hard is it to utilize this in-app/game so that you can use it to charge and then download in-app/game right away? If they haven't set up an account to buy anything on market, they are going to have to fill in that info anyway to buy anything. Actually.. come to think of it.. if you charge for your main app..they already set it up. I would have thought the info would be in some way available..not their private stuff, but the google checkout info, so that you could utilize it somehow? I'll have to look into it more as this is how I would do it. Another thought..perhaps to get more virtual toon sales, give your game away (if you aren't already), with 1 toon, and put your own little splash-screen "ads" for other toons as the app loads up. This may interest users in supporting your app and buying even more toons than if they already paid for the app. Also, look at custom creation of toons/avatars.. for perhaps a $2 charge for example. Again, not at all clear on your app and it's ideas, but just some food for thought on how you might make a little more from it.
