android support v7 gradle jacket - BONGDATV

guys i have android studio 3.4.1 and i want know how can import import android.support.v7.app.AppCompatActivity; this to my library. need help plss

configurations { all*.exclude group: 'com.android.support', module: 'support-v4' }

I'm trying to figure out why the heck my Android studio isn't recognizing the AppCompat v7 library correctly. The import statement below shows up as gray and says there's no package for support.v7.app. Below is my activity file: import android.support.v7.app.AppCompatActivity;

The Support Library is a static library that you can add to your Android application in order to use APIs that are either not available for older platform versions or utility APIs that aren't a part of the framework APIs.
