Android Studio 2.0, which is still just accessible as a see discharge, has further developed highlights like moment run and a GPU profiler to additionally improve the application advancement experience.

Android Studio additionally accompanies a sensible emulator you can utilize in the event that you don’t possess an Android gadget. Since framework pictures for it are uninhibitedly accessible, you can download and run any adaptation of Android on it.

Developing an Android application that runs well on one explicit Android telephone or tablet is simple. Developing one that runs well on all Android gadgets, be that as it may, can be staggeringly hard as a result of the huge contrasts in working framework variants, screen sizes, and gadget capacities.

In contrast to Apple’s iOS gadgets, most Android gadgets once in a while get programming refreshes, if by any means. Marshmallow, the most recent rendition of Android, runs on under 1.5% of all Android gadgets today, despite the fact that it was delivered a while prior.
