How to build multiple projects in the correct order of dependency with Android NDK?

I have a series of existing libraries that I need to reuse in an Android app. The layout is similar to:

\ Libraries \ libOne
\ Libraries \ libTwo [Static Library]
\ Libraries \ libThree
\ Applications \ MyApplication \ [Application]

libTwodepends on libOne, but libThreedepends on libTwo. How can I get the build system to assemble all the libraries in the correct order? I am trying to use Eclipse, but if necessary I can use the command line.

All of these libraries will eventually be referenced by a Java application (and use the JNI to interact with them). Any tips on how I'm setting up Android.mk/Application.mk files?

I tried using BUILD_STATIC_LIBRARYfor libTwo, but actually it does not output any files! I was expecting a file libTwo.a, but nothing compiles or builds.

Am I writing one Android.mk in an application? Or Android.mk for each project?

OK, now I see your editing, and this allows you to answer a specific question.

update Android.mk jni:
