title: How to write Android.mk for library using Gnu makefile
body: <p>I want to make an Android application using huge third party native libraries which use the Gnu build tools (gnu makefile).</p>
  
  <p>My question is how to write the "Android.mk" files for these libraries in order to build them using the Android build system or the Android NDK.</p>
  
  <p>Thanks in advance</p>
