Add dumpsys integration for the native input dispatcher. Add some InputDevice API stubs. Add an appendFormat helper method to String8 for printf style string formatting mainly for debugging purposes. Use generic ArrayList<WindowState> everywhere in WindowManagerService to eliminate unnecessary casts all over. Change-Id: I9d1e3bd90eb7222d10620200477f11b7bfd25e44
Android Utility Function Library If you need a feature that is native to Linux but not present on other platforms, construct a platform-dependent implementation that shares the Linux interface. That way the actual device runs as "light" as possible. If that isn't feasible, create a system-independent interface and hide the details. The ultimate goal is *not* to create a super-duper platform abstraction layer. The goal is to provide an optimized solution for Linux with reasonable implementations for other platforms.
