Android supportability and incompatibility is so unclear

Question

what is the version of android from which further on there is no concept of incompatibility(no need of support libs). I am a newbie and this supporting and non supporting thing is making it so boring. I just want to know of a stable version from which I should take start and do not use support libraries (like appcompat, sherlock, etc). Also tell me if I am doing a wrong thing doing this I mean anything that will help me. Thanks Any relevant help is appreciated.

Answer 1

As an app developer, you'd like your app to run on as many devices as possible. Generally, developers give support from API level 8 (Android 2.2) and upwards.

Most of the compatibility libraries are for pre-API 11 (HoneyComb).

So basically, it depends upon what you want to aim for.
