Question

I try to use compileSdkVerion 21 and targetSdkVersion 21. See the second picture bellow, my project just compileSdkVersion 21 and library at version 21. How value-23, value-24 and value-26 exist there? I have tried many ways:

1. Delete build folder
2. Uninstall/install sdk plaform
3. Clean/Rebuild will get error bellow.

Answer 1

These are the Only solution for it:- 1. Deprecate your android studio. 2. Use only lib 23 build element 3. Don't use this element like this

compile RecyclerView'27.0.1'

use only

compile RecyclerView'23.0.0'
