/*
* This goofy move needs some explanation.
*
* The verifier on older platform versions has some interesting side effects if
* a class defines a method that takes a parameter of a type that doesn't exist.
* In this case, that type is android.view.ActionMode. Therefore, ActionBarActivity
* cannot override the onActionModeStarted/Finished methods without causing nastiness
* when it is loaded on older platform versions.
*
* Since these methods are actually part of the window callback and not intrinsic to
* Activity itself, we can install a little shim with the window instead that knows
* about the ActionMode class. Note that this means that any new methods added to
* Window.Callback in the future won't get proxied without updating the support lib,
* but we shouldn't be adding new methods to public interfaces that way anyway...right? ;)

Can not run on pre 4.0 Devices like 2.3. You should improve it.

I wasn't writing it for android 2.3 initially because it contributes to a very small percentage of devices. My aim was thumbing on 4.0+. Hopefully, you can check where there are issues and suggest some changes, since you have access to a testing device running 2.3.
