I’m pretty new to layouts, but I was able to successfully make a pretty nice looking layout (for a tablet). In Eclipse, it works great. I made it all with the ‘target’ on Android 4.0 (ICS), but obviously my tablet only runs 3.0 (Honeycomb). When I realised the error, I changed the viewer/editing config to 3.2, but Eclipse won’t even display the graphic of the layout anymore, it simply spits out:

com.android.layoutlib.bridge.MockView cannot be cast to android.view.ViewGroup
    Exception details are logged in Window > Show View > Error Log
    The following classes could not be found:
    - GridLayout (Change to android.widget.GridLayout, Fix Build Path, Edit XML)

The error log pops out:

java.lang.ClassCastException: com.android.layoutlib.bridge.MockView cannot be cast to android.view.ViewGroup

And here is my layout:

Ultimately, I’m able to install the app on my tablet, but it just crashes right away with this from LogCat:

Will re-making the whole layout with 2.3 selected fix this problem? That’s sooo sucky…
