This is the Android companion app to Mycroft-core. It works by opening a websocket connection to the Mycroft-core messagebus and sending and receiving messages from there.

It implements voice recognition and Text To Speech (TTS) via Google API's at the moment, but that may change soon.

To Install

Import the repo into Android Studio, or your IDE of choice. Build and deploy to a device

Once the app is running on a device (Lollipop or later SDK 24), you will need to set the IP address of your Mycroft-core instance in the Settings -> General Options menu. That will then create a websocket connection to your Mycroft and off you go!

Coding style...

We have moved now to Kotlin and therefore will be following the standard coding practices. Also please use descriptive method/function names. And use comments to back up that name when complicated, like a calculation or similar. Remember, you want to come back 6 months from now and be able to read your code.

Most of all have fun. Ask questions and don't worry about breaking anything, that is why we have a versioning system.


Android companion app, sends commands from your Android device to your Mycroft system and returns the output as speech or other medium to the Android device.
