Exception raised during rendering in Eclipse

I have an error in Android xml layout as follows :
Exception raised during rendering: <include /> can only be used inside of a ViewGroup
Exception details are logged in Window > Show View > Error Log
The following classes could not be found:
- android.support.v7.internal.widget.ActionBarOverlayLayout (Fix Build Path, Edit XML, Create Class)
Now, When I am changing the AppTheme to Theme.Holo than its working fine.
I want to know that Why is it like this ?

Android XML layout NullPointerException

java.lang.NullPointerException Exception details are logged in Window > Show View > Error Log
The following classes could not be instantiated:
- android.support.v7.internal.app.WindowDecorActionBar (Open Class, Show Error Log)
- android.support.v7.internal.widget.ActionBarContextView (Open Class, Show Error Log)
- android.support.v7.widget.Toolbar (Open Class, Show Error Log)
See the Error Log (Window > Show View) for more details.

Go to File > Invalidate Caches/Restart. This should help your IDE restore the cache since this is just an issue with the renderer. Worked for me for the same exception.

Layout rendering error

System did not generate an Id for my new xml layout and show me same errors

I have 2 problem that I think both of them is for one reason:
When I try to add a new XML layout; that XML fail add successfully but in "Console" show me it:
[2014-05-04 18:41:11 - Example] W/ResourceType( 5804): ResXMLTree_node size 0 is smaller than header size 0x14.
[2014-05-04 18:41:11 - Example] D:\Android\Workspace\Example\res\menu\main.xml:4: error: Error: Resource id cannot be an empty string (at 'actionLayout' with value '#android:layout/').
and I can get resource to it in classes.
In "problem" tab:
Errors: Unparsed aapt error(s)! Check the console for output.
Location: line 1
Type: Android ADT Problem
and I cant solve it
Please same one help me ...

I sorted this out. So for anyone else still on the learning curve with me, the solultion is as noted in my comment. In addition -
aapt = Android Asset Packaging Tool From the Developers Guide - "The Android Asset Packaging Tool (aapt) takes your application resource files, such as the AndroidManifest.xml file and the XML files for your Activities, and compiles them."
The solution for me was simply to delete the error on the 'Problem' window (right click | delete). Then, force a rebuild by rerunning the app. Any remaining problems will now show up and be logged so you can track them down.
Hope this is helpful to others.

Yesterday my system is force shut-downed unfortunately without saving the eclipse workspace. After that i got this error while opening the graphical view of the android layout files. But no error in xml files. They are perfect working files.
Any help would save my life. I'm struggling more than one day at a tight deadline.

I got this king of error during a maven build in eclipse.
I deleted the contents of directory that eclipse builtin maven use to store downloaded files under
$HOME/.m2/repository
ant executed the clean target and rebuild.
Maybe it holds some stuff for android too.
