Android Studio Not Working while building App using AppCompat v23 and API21

Question

I am using Android 1.3 version and SDK for 5.0.1 I decrepeted it because whenever I build project it throws error.

Can anyone please tell in detail

Answer 1

You are using the appcompat (and other support libraries) v23 .
You have to compile your project with API 23.

Change in your build.gradle the compileSdkVersion to 23
