commit d6f9e415375f53eba7c5e147c7ff30c03a6db731
Author: Jacobo Aragunde Pérez <jaragu...@igalia.com>

    Android: download documents from ownCloud.
    
    Documents are downloaded to the private cache directory of the app,
    and opened from there. That directory is cleared and created again
    every time the application starts up.
