Android Studio Rendering Problems : The following classes could not be found

I just update Android Studio, and when I restarted it, the preview window rendering failed, and I was told that

The following classes could not be found: - android.support.v7.internal.widget.ActionBarOverlayLayout

If someone can tell me what can I do to fix this rendering problem? Thank you.

You have to do two things:

  • be sure to have imported right appcompat-v7 library in your project structure -> dependencies
  • change the theme in the preview window to not an AppCompat theme. Try with Holo.light or Holo.dark for example.

Please see the following link - here is where I found a solution that worked for me.

Rendering problems in Android Studio v 1.1 / 1.2

Changing the Android Version when rendering layouts worked for me - I flipped it back to 21 and my "Hello World" app then rendered the basic activity_main.xml OK - at 22 I got this error. I borrowed the image from this posting to show you where to click in the Design tab of the XML preview. What is wierd is that when I flip back to 22 the problem is still gone :-).

I had to change my values/styles.xml to

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">

Before that change, it was without 'Base'.

(IntelliJ IDEA 2017.2.4)

I have faced this issue when I introduced additional supporting libraries in my project IntelliJ IDEA

So for me "File" -> "Invalidate Caches...", and select "Invalidate and Restart" option to fix this.
