After Updating Android studio to 3.1.2 , I get “Failed to load AppCompat ActionBar with unknown error. ”

Question

I tried looking other similar questions on stackoverflow, they advice us to changw version of \"buildToolsVersion\" but I dont see word like that in my gradle file.

Answer 1

At the time of this answer Android Studio 3.1.4 is out with Android Support 28.0.0 Release Candidate(Potential Final, Beta) so please update. Well, here is a config that will certainly work for you.

targetSdkVersion 28
com.android.support:*:28.0.0-rc01

Where * is the resource type.
