How to get android's native methods source code

Question

Is it possible to get and watch at Android's program component's native methods code. If anyone knows how to, please let me know.

Answer 1

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

• AndroidXRef
• GitHub (using repo:android/* search term)

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.
