react-native-androidtv-remote

This package is a port of the Android TV Remote written by @louis49 to React Native

• License: MIT (see LICENSE file)

It has beeen modified to replace modpow that is too slow on ios/android during the generation of the certificate and I have added the possibility to use a certificate when using react-native-tcp-sockets (dev/more-node-tls-compliant-ios).

Installation

Install the library using either yarn:

yarn add react-native-androidtv-remote react-native-modpow

or npm:

npm install --save react-native-androidtv-remote react-native-modpow

BEWARE: at the time of writing these instructions, my dev/more-node-tls-compliant-ios branch has not yet been merged into react-native-tcp-sockets, so it is necessary to patch it using patch-package.

So inside your project add patch-package:
yarn add patch-package

Then copy the folder example/patches inside your project and add inside package.json

"scripts": {
    ...
    "postinstall": "patch-package"
  },

Example

react-native-androidtv-remote-270x480.mp4

To run the example:

android

cd example
yarn install
yarn start

on another terminal:
yarn android

iOS

cd example
yarn install
cd ios
pod install
cd ..
yarn ios

If you want to deploy on a real iPhone device you might need to open TestAndroidTVRemoteApp.xcworkspace, double click on TestAndroidTVRemoteApp on the left and goes to 'Signing and Capabilities' to check 'Automatically manage signing' and choose your Team.

on another terminal:
yarn ios

Usage

After first succeeded pairing, you can reuse generated certs with getCertificate() by sending it in constructor options.

let host = "192.168.1.12";
let options = {
    pairing_port : 6467,
    remote_port : 6466,
    service_name: 'com.urcompany.appname',
    systeminfo: {
      manufacturer: 'default-manufacturer',
      model: 'default-model'
      },
      // Mandatory for the connection to work on android and needs patched version of
      // react-native-tcp-socket
      cert: {
        key: null,
        cert: null,
        androidKeyStore: 'AndroidKeyStore',
        certAlias: 'my-remotectl-atv-cert',
        keyAlias: 'my-remotectl-atv',
      }
}

let androidRemote = new AndroidRemote(host, options)

androidRemote.on('secret', () => {
    line.question("Code : ", async (code) => {
        androidRemote.sendCode(code);
    });
});

androidRemote.on('powered', (powered) => {
    console.debug("Powered : " + powered)
});

androidRemote.on('volume', (volume) => {
    console.debug("Volume : " + volume.level + '/' + volume.maximum + " | Muted : " + volume.muted);
});

androidRemote.on('current_app', (current_app) => {
    console.debug("Current App : " + current_app);
});

androidRemote.on('ready', async () => {
    let cert = androidRemote.getCertificate();

    androidRemote.sendKey(RemoteKeyCode.MUTE, RemoteDirection.SHORT)

    androidRemote.sendAppLink("https://www.disneyplus.com");
});

let started = await androidRemote.start();

Events

Event: secret

Emitted when androidtv ask for code.

Event: powered

Emitted when androidtv is powering on/off.

Event: volume

Emitted when androidtv is changing volume/mute.

Event: current_app

Emitted when androidtv is changing current app.

Event: error

Emitted when androidtv has a problem : by example when you send a wrong app_link with sendAppLink(app_link).

Commands

Command: sendCode(code)

• code : You need to pass the shown code on the TV when asked

Command: sendKey(KeyCode, Direction)

• KeyCode : Any key of https://developer.android.com/reference/android/view/KeyEvent?hl=fr
• Direction :
  • START_LONG : Start long push
  • END_LONG : Stop long push
  • SHORT : Simple push

Command : sendAppLink(app_link)

• app_link : You can find them in some Android apps by seeking 'android:host' in Android-Manifest
  • You can use jadx to decompile the Android app and read Android-Manifest
  • Example : "https://www.netflix.com/title.*"

Others

• If you need to decrypt some new messages from android TV, pass an Hexa form of buffer here : https://protogen.marcgravell.com/decode
• You can take a look at an other package for homebridge that use this current one: homebridge-plugin-androidtv
