Hey Hassan Osman, for your first step, try out the solution posted here on StackOverflow: http://stackoverflow.com/a/30253591/475217

After that you'll need to click on the Gradle Sync button (the one with the green arrow pointing down). That may pull in the required classes to fix your rendering problems. If not, post back here with details. :smile:

Hi,

I tried the solution in Stack Overflow then followed your instructions after that and I'm still getting an error:

Rendering Problems The following classes could not be instantiated: - android.support.v7.internal.widget.ActionBarOverlayLayout (Open Class, Show Exception, Clear Cache) Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE Exception Details java.lang.NoClassDefFoundError: Could not initialize class android.support.v7.internal.widget.ActionBarOverlayLayout   at java.lang.reflect.Constructor.newInstance(Constructor.java:422)   at android.view.LayoutInflater.inflate(LayoutInflater.java:482)   at android.view.LayoutInflater.inflate(LayoutInflater.java:414)   at com.android.layoutlib.bridge.bars.BridgeActionBar.<init>(BridgeActionBar.java:84)   at com.android.layoutlib.bridge.bars.AppCompatActionBar.<init>(AppCompatActionBar.java:56) Copy stack to clipboard

Any ideas what else I can try. Also, i downloaded JDK SE Development Kit 8 instead of 7 - do you think this is causing the problem?

So apparently it is a known issue that there is a rendering problem with the theme. Here is the link to the bug -> https://code.google.com/p/android/issues/detail?can=2&start=0&num=100&q=&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars&groupby=&sort=&id=78944

If you change the theme by clicking on the theme button locked directly in the middle above the preview box. I selected the Android:Theme.Holo and the preview worked fine.
