Where is PackageManager.movePackage()?

Checki开发者_如何学运维ng the Android Documentation, such method is not present. But looking in the Source code for Application Manager (the built in one) it uses:

 mPm.movePackage(mAppEntry.info.packageName, mPackageMoveObserver, moveFlags);

the movePackage() method, while looking in the source code (for 2.2 Froyo, API) such method is there and declared as public abstract. I wonder how can I access this method?
