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.

Make the changes in your build.gradle (app level) to downgrade to version 27 as below. Then sync and build project. Hopefully it will fix the issue..

compileSdkVersion 27

targetSdkVersion 27

implementation 'com.android.support:appcompat-v7:27.1.1'
