Yes, it happens. You can fix it easily.

First Method: Open build.gradle(Module: app) under Gradle Scripts and change version alpha3 to alpha1 and Sync now

implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'

Second Method: Open style.xml under res -> values -> style.xml and change this line

style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

put Base. before Theme.AppCompat.Light.DarkActionBar like

style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">

Hope problem will be solved.
