I did create a new project.
Xcode works, but android not works.
What’s this problem?
Don’t use precomiled for android project.
Don’t bother getting the answer. I asked many times and never got an answer 
Just “don’t” without explanation. I’m using precompiled version and running it from console - it’s way faster compilation and project is lightweight.
No, I don’t. I’d love to (debugging, multidex etc), but it’s unusable for now. Just look at @SonarSystems tutorial about Android Studio. You have to open 2 windows - for android code and second for c++ code. As far as I know you can only debug java code. And build is done by cocos console anyway (so no gradle). @slackmoehrle said that it’s possible to do these things, but I couldn’t find how to do that.
You can only debug Java at this time. This is an Android Studio limitation, not the engine.
