Creating a product SDK: How do I add a native lib (.SO) and a jar with the SDK I am creating?

I'm trying to use com.android.SystemClock in an app, which calls a native method. I need to load the library that this native method belongs to (i.e. System.loadLibrary(...)). The method is defined in the file: frameworks/base/core/jni/android_os_SystemClock.cpp. How do I figure out which library this belongs to and load it as well?

Inspect the make files and find out what libs it builds. Look for LOCAL_MODULE. That said, it is probably in libandroid_runtime.so.

And then again, if it is not part of the public SDK, you shouldn't be using it. It may change, break, not work on some devices, etc.

thanks. How do I load this .so file? System.loadLibrary("libandroid_runtime") throws an UnsatisfiedLinkError. – user1193425 Feb 09 '12 at 22:51
On Linux, the 'lib' is a prefix, not a part of the library name. Try `loadLibrary("android_runtime")`. – Nikolay Elenkov Feb 10 '12 at 01:10
