Answer 1

You must update your

compileSdkVersion 28   &   targetSdkVersion 28

then Use

   implementation 'com.android.support:appcompat-v7:28.0.0'
   implementation 'com.android.support:design:28.0.0'

This is the stable release of Support Library 28.0.0 and is suitable for use in production. This will be the last feature release under the android.support packaging, and developers are encouraged to migrate to AndroidX.
