Shuttle Xpress Driver for android

This is an Android library which can be used to incorperate user input from a Contour design Shuttle Xpress into an Android application.

The library has been used in my Headunit Controller App, but other usage can be found in the example app.

The library currently requires API 17 or higher, due to a limitation of the UsbRequests API (This may be lowered in the future)

Usage

Connecting

ShuttleXpressConnection connection = new ShuttleXpressConnection(context);
ShuttleXpressDevice device = connection.getDevice();

// Show a notification to show the device is connected
connection.setShowNotifications(wantNotification);

// Request to open a connection
connection.open();

Interface

// UI Updates can be performed through the listeners

connection.registerConnectionChangeListener(new ShuttleXpressConnection.ConnectionStateChangeListener() {
    @Override
    public void onChange(int newState) {
        if (newState == ShuttleXpressConnection.STATE_CONNECTED) {
            ...
        }
    }
});


device.registerKeyListener(new ShuttleXpressDevice.KeyListener() {
    @Override
    public void onDown(int id) {
        if (id == ShuttleXpressDevice.KeyCodes.WHEEL_LEFT) {
            // Wheel has clicked left
        } else if (id == ShuttleXpressDevice.KeyCodes.WHEEL_RIGHT) {
            // Wheel has clicked right
        }
    }

    @Override
    public void onUp(int id) {
        if (id == ShuttleXpressDevice.KeyCodes.BUTTON_0) {
            // Button 0 has finished being pressed
        }
    }
});

Or read values manually:

for (int i = 0; i < 5; i++) {
    Log.v(TAG, String.valueOf(device.getButtonState(i)));
}

Log.v(TAG, String.valueOf(device.getRingState()));
Log.v(TAG, String.valueOf(device.getRingPosition()));
Log.v(TAG, String.valueOf(device.getWheelPosition()));

Adding Shuttle Xpress your Android Studio project

Easier method

1. git clone https://github.com/freshollie/shuttle-xpress-android.git wherever you wish
2. Open your android studio project
3. File -> New -> Import module: path/to/shuttle-xpress-android/shuttle-xpress-library

Done. However you will need to manually to update the sourcecode in your projects directory when this library updates.

Better method

1. Go to your project root directory
2. git submodule add https://github.com/freshollie/shuttle-xpress-android.git
3. git sudmodule update shuttle-xpress-android
4. Open settings.gradle
5. Add include ':shuttle-xpress-library'
6. And project(':shuttle-xpress-library').projectDir = new File('shuttle-xpress-android/shuttle-xpress-library')
7. Finally open app/build.gradle
8. And add compile project(':shuttle-xpress-library') to the build dependencies

Brilliant, now your app repository contains this library as a submodule, which can easily be update with git pull inside from inside the module directory

To sync the submodule after a clone

git submodule init; git submodule update shuttle-xpress-android
