Render error in Android Studio 3.0 Layout Editor

Question

I just started learning Kotlin for android development and started an empty project and added an activity. I have added the required gradle dependencies as said in Kotlin docs. By default the xml file of MainActivity contains only a TextView. But when I try to preview the xml in Layout Editor it shows a "Render Error"

Render problem  Failed to load AppCompat ActionBar with unknown error. 

Also I'm getting this

The following classes could not be instantiated: - android.support.v7.widget.AppCompatImageView (Open Class, Show Exception, Clear Cache) - android.support.v7.widget.ActionBarContainer (Open Class, Show Exception, Clear Cache) - android.support.v7.widget.Toolbar (Open Class, Show Exception, Clear Cache) - android.support.v7.widget.AppCompatTextView (Open Class, Show Exception, Clear Cache) - android.support.v7.widget.ActionBarContextView (Open Class, Show Exception, Clear Cache) - android.support.v7.app.WindowDecorActionBar (Open Class, Show Exception, Clear Cache) - android.support.v7.widget.ActionBarOverlayLayout (Open Class, Show Exception, Clear Cache)   Exception Details java.lang.ClassNotFoundException: android.support.v4.view.TintableBackgroundView 

I have tried rebuilding the project and refreshing layout manually. But nothing seems to work.

So what do I do? I'm using Android Studio 3.0 Canary 2 with Kotlin

EDITED:

I have made some progress. I have found that none of my AppCompat Themes are working.

Answer 1

This solution may help you. Modify style.xml from:

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

to:

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

I also have this problem, solved as follows: modify the appcompat-v7:26.0.0-beta2 on build.gradle (modle:app) to appcompat-v7:26.0.0-beta1.
