Android TV integration for Remote Two

Using androidtvremote2 and uc-integration-api.

The integration currently supports almost all features that the androidtvremote2 library provides. Button control and ON/OFF states are supported. Unfortunately media image and playing information are not retrievable. Source list is limited to a predefined list as retrieving a list of installed apps is not possible.

This integration is included in the Remote Two firmware and no external service must be run to connect with Android TV devices. A standalone service can be used for development or connecting multiple devices.

Requirements and setting.
Multiple Android TV devices are supported with version 0.5.0 and newer.
Device profiles allow device specific support and custom key bindings, for example double-click or long-press actions.
See command mappings for more information.

Standalone Usage

Setup

Requires Python 3.11
Install required libraries:
(using a virtual environment is highly recommended)

pip3 install -r requirements.txt

For running a separate integration driver on your network for Remote Two, the configuration in file driver.json needs to be changed:

Set driver_id to a unique value, uc_androidtv_driver is already used for the embedded driver in the firmware.
Change name to easily identify the driver for discovery & setup with Remote Two or the web-configurator.
Optionally add a "port": 8090 field for the WebSocket server listening port.
- Default port: 9090
- Also overrideable with environment variable UC_INTEGRATION_HTTP_PORT

Run

UC_CONFIG_HOME=./config python3 intg-androidtv/driver.py

See available environment variables in the Python integration library to control certain runtime features like listening interface and configuration directory.
The client name used for the client certificate can be set in ENV variable UC_CLIENT_NAME. The hostname is used by default.

Build distribution binary

After some tests, turns out Python stuff on embedded is a nightmare. So we're better off creating a binary distribution that has everything in it, including the Python runtime and all required modules and native libraries.

To do that, we use PyInstaller, but it needs to run on the target architecture as PyInstaller does not support cross compilation.

The --onefile option to create a one-file bundled executable should be avoided:

Higher startup cost, since the wrapper binary must first extract the archive.
Files are extracted to the /tmp directory on the device, which is an in-memory filesystem.
This will further reduce the available memory for the integration drivers!

x86-64 Linux

On x86-64 Linux we need Qemu to emulate the aarch64 target platform:

sudo apt install qemu binfmt-support qemu-user-static
docker run --rm --privileged multiarch/qemu-user-static --reset -p yes

Run PyInstaller:

docker run --rm --name builder \
    --platform=aarch64 \
    --user=$(id -u):$(id -g) \
    -v "$PWD":/workspace \
    docker.io/unfoldedcircle/r2-pyinstaller:3.11.6  \
    bash -c \
      "python -m pip install -r requirements.txt && \
      pyinstaller --clean --onedir --name intg-androidtv intg-androidtv/driver.py"

aarch64 Linux / Mac

On an aarch64 host platform, the build image can be run directly (and much faster):

docker run --rm --name builder \
    --user=$(id -u):$(id -g) \
    -v "$PWD":/workspace \
    docker.io/unfoldedcircle/r2-pyinstaller:3.11.6  \
    bash -c \
      "python -m pip install -r requirements.txt && \
      pyinstaller --clean --onedir --name intg-androidtv intg-androidtv/driver.py"
