Are you asking about the best IDE for Android Development, or the best IDE which runs on Android?

Answer 2

Best IDE for Android

Answer 3

Android Studio will make life look easy when you get how to use it and good pc to run it

Answer 4

I assume that you are talking about IDE, that runs C++, and is available for Android devices.

I'd recommend this:
https://play.google.com/store/apps/details?id=ru.iiec.cxxdroid

But there are more, just search with keyword "cppdroid" in Google Play Store and you should find good IDEs.
