Xposed cannot hook internal services in 5.x

[PeterCxy]

If you try to do this, the system process will Crash, crash, and crash, but we need to hook some internal service class to get the status bar transition and animation work correctly. Any ideas?

Without hooking these methods (especially those in ActivityManager implementations), we cannot even fix errors in apps like Snapchat. I have no idea, so I think I really need help.
