DisplayThreadpublic final class DisplayThread extends ServiceThread | Shared singleton foreground thread for the system. This is a thread for
operations that affect what's on the display, which needs to have a minimum
of latency. This thread should pretty much only be used by the WindowManager,
DisplayManager, and InputManager to perform quick operations in real time. |
