commit 143fb0a4b5d4ab69d4928299d8112ab95d99870a
Author: Christian Lohmaier <lohmaier+LibreOffice at googlemail.com>
Date:   Sun Oct 11 01:52:39 2015 +0200

    move extracting assets to Java & use AssetManager to access assets
    
    using AssetsManager in both java as well as native parts allows to
    handle files both with and without compression transparently

commit ee8257a1c70eadb7330b0ee99ec3b86fe4084bdf
Author: Christian Lohmaier <lohmaier+LibreOffice at googlemail.com>
Date:   Sun Oct 11 01:53:29 2015 +0200

    migrate android build to gradle
    
    move preparation tasks (creating assets/processing files) from the
    makefile into the gradle script
    
    This allows much easier integration into android-studio (just open
    android/source with android studio after running make to compile the
    native library)
