I've been removing external libraries from my project because I was getting bugs from mixed versions of the appCompat library, I tried to delete everything related to version 25.2.0 because I need to use 22.2.1% with%. The error happens when I try the Gradle sync, see the image:
How can I readitize what is required of me.
UPDATE:
I get this error if I try to build:
Error: Could not resolve all files for configuration ': app: debugCompileClasspath'.
Could not find support-annotations.jar (com.android.support:support-annotations:25.2.0). Searched in the following locations: file: / G: /Static/Android/sdk/extras/android/m2repository/com/android/support/support-annotations/25.2.0/support-annotations-25.2.0.jar
