very good post. enjoyed reading about your experience. I also think you should write more on 1) learning Android development (maybe tutorials for the novice) & 2) more on marketing. Like you, I am new to mobile app development/business. Learned Android development first but then got into iOS. For now, sticking mostly with iPhone. It’s way different but the idea is “fish where the fishes are”. I like Android but to me at this point, it’s good for consumer but kind of harsh for developers. People ask for refunds on Android apps and they can continue to use the app moving it to the SD card. Glad you are trying out different things on marketing. I am doing the same and my first app is no out yet :-) Apple still reviewing it. You are correct on graphics. I think that is mighty important. I am sharing my journey of app development, marketing and overall experience through my blog too. Check it and share your thought. Good luck!
