""" pyside6-android-deploy deployment tool

    Deployment tool that uses buildozer (https://buildozer.readthedocs.io/en/latest/) and
    python-for-android (https://python-for-android.readthedocs.io/en/latest/) to deploy PySide6
    applications to Android

    How does it work?

    Command: pyside6-android-deploy --wheel-pyside=<pyside_wheel_path>
                                    --wheel-shiboken=<shiboken_wheel_path>
                                    --ndk-path=<optional_ndk_path>
                                    --sdk-path=<optional_sdk_path>
             pyside6-android-deploy android -c /path/to/pysidedeploy.spec


    Note: If --ndk-path and --sdk-path are not specified, the defaults from buildozer are used

    Prerequisities: Python main entrypoint file should be named "main.py"

    Platforms Supported: aarch64, armv7a, i686, x86_64

    Supported Modules: Core, Gui, Widgets, Network, OpenGL, Qml, Quick, QuickControls2

    Config file:
        On the first run of the tool, it creates a config file called pysidedeploy.spec which
        controls the various characteristic of the deployment. Users can simply change the value
        in this config file to achieve different properties ie. change the application name,
        deployment platform etc.

        Note: This file is used by both pyside6-deploy and pyside6-android-deploy
