The ``.apk`` file will then be available in ``$TUTOR_ROOT/data/android``. Transfer it to an Android phone to install the application. You should be able to sign in and view available courses.
Releasing an Android app
------------------------
**Note**: this is an untested feature.
Releasing an Android app on the Play Store requires to build the app in release mode. To do so, edit the ``$TUTOR_ROOT/config.yml`` configuration file and define the following variables::
ANDROID_RELEASE_STORE_PASSWORD
ANDROID_RELEASE_KEY_PASSWORD
ANDROID_RELEASE_KEY_ALIAS
Then, place your keystore file in ``$TUTOR_ROOT/env/android/app.keystore``. Finally, build the application with::
tutor android build release
Customising the Android app
---------------------------
Customising the application, such as the logo or the background image, is currently not supported. If you are interested by this feature, please tell us about it in the Tutor `discussion forums <https://discuss.overhang.io>`_.
