How to get android's native methods source code

You can find source code for Android native methods using ~~Google Code Search~~ one of the following services:

The search for "SystemClock || android*SystemClock" in AndroidXref will point you to the android_os_SystemClock.cpp file which in turn forwards many of its methods to SystemClock.cpp

Other Android .cpp or .h files with native methods implementations could be found in a similar way.
