An * instance of it is created by the window manager when it starts up, and allows * customization of window layering, special window types, key dispatching, and * layout. * *

Because this provides deep interaction with the system window manager, * specific methods on this interface can be called from a variety of contexts * with various restrictions on what they can do. These are encoded through * a suffixes at the end of a method encoding the thread the method is called * from and any locks that are held when it is being called; if no suffix * is attached to a method, then it is not called with any locks and may be * called from the main window manager thread or another thread calling into * the window manager. * *

The current suffixes are: * *

*
Ti
Called from the input thread. This is the thread that * collects pending input events and dispatches them to the appropriate window. * It may block waiting for events to be processed, so that the input stream is * properly serialized. *
Tq
Called from the low-level input queue thread. This is the * thread that reads events out of the raw input devices and places them * into the global input queue that is read by the Ti thread. * This thread should not block for a long period of time on anything but the * key driver. *
Lw
Called with the main window manager lock held. Because the * window manager is a very low-level system service, there are few other * system services you can call with this lock held. It is explicitly okay to * make calls into the package manager and power manager; it is explicitly not * okay to make calls into the activity manager or most other services. Note that * {@link android.content.Context#checkPermission(String, int, int)} and * variations require calling into the activity manager. *
Li
Called with the input thread lock held. This lock can be * acquired by the window manager while it holds the window lock, so this is * even more restrictive than Lw. *
