I am an Indie developer for iOS. I just got started with Unreal Engine because you claim to support iOS and Android. Your editor, engine, and tutorials are first-rate. This is certainly the best engine out today. The problem I have is your claim to support Android development. As it stands today, this is wrong.
I tried getting TappyChicken to work on Three devices now (I went out and bought a GalaxyTab today.) It doesn’t work on any of them. I understand when you released TappyChicken, you were using updates not yet available as of the current version - 4.2.1. I also understand you will have more support for Android in version 4.3, but currently your support for android is almost non-existent, so I wouldn’t claim Android compatibility yet. I know you guys are excited, but you are turning off a lot of your customers who are coming from Unity, where Android support is excellent.
May I suggest you call Android support experimental until you get the kinks out. It doesn’t look good.
