As part of this change, consolidated and cleaned up the Looper API so that there are fewer distinctions between the NDK and non-NDK declarations (no need for two callback types, etc.). Removed the dependence on specific constants from sys/poll.h such as POLLIN. Instead looper.h defines events like LOOPER_EVENT_INPUT for the events that it supports. That should help make any future under-the-hood implementation changes easier. Fixed a couple of compiler warnings along the way. Change-Id: I449a7ec780bf061bdd325452f823673e2b39b6ae
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.
