Cannot figure out the difference between PhoneWindowManager and WindowManagerService

[Kunal Sinha]

Hi,

Both PhoneWindowManager and WindowManagerService implement WindowManagerPolicy and as such overriding its functions for handling the window

Can anyone please me the difference between the PhoneWindowManager and WindowManagerService?

Thanks,
Kunal

WindowManagerService is the core window manager.  PhoneWindowManager implements higher-level policies for the service, such as how to interact with the status bar, default handling of keys like home, etc.  WindowManagerService generally calls on to PhoneWindowManager (via the WindowManagerPolicy interface) at key points in its operation where some non-generic policy may be decided.
