Is unity more efficient than eclipse for Android game development? [Closed]

It's much easier and faster to use Unity.
If you want to create a game from zero with Eclipse, you must implement Unity equivalent features yourself.

I think it's good to read the manual or help in Eclipse or unity, and then listen to specific problems such as not knowing.

Google recommends Android Studio, so I think you should check it out as well.

You should also read the Stack Overflow documentation.
