I've learned tons of stuff releasing this app, not so much about programming but of how to handle user comments, feature requests, bug corrections and just make to TEST before you release.
Obviously you want a good rating of the app on Android market but it's surprisingly hard to not care when someone give it a bad rating. Even if the comment suggests that the user doesn't know what he's talking about:
I thought this was going to be like a vertual rubics cube little did i know its faaarr from it[,] this stuff is like triginomatryThis user gave the app a rating of one, even though he clearly didn't read the description of the app. Not everyone will like what you're doing, no matter how much effort you put into it.
I've also seen a few users reporting bugs in app comments. Which is frustrating since i can't contact them through the comment system and i don't think they realize this. It would be really nice to have an issue tracker integrated into android market, to be able to communicate to the users what bugs that exists and what i'm working on.
Anyway, i'm happy that some people appreciate the app because I've put a lot of hours into it. And hopefully i can iron out the few existing bugs in the coming releases. But right now I will continue my vacation over in Asia until spring.
