UsbHid

Another custom USB HID host library for Android. Inspired by:
https://android.serverbox.ch/?p=549
https://github.com/benlypan/UsbHid
https://github.com/yutils/yutils/blob/master/utils/src/main/java/com/yujing/utils/YUsb.kt

Benefits

• Register device vid:pid and the library will notify you, i.e. via events, if device is not found, connected, or disconnected.
• The library will request permission to use device (if needed)
• You can extend the UsbHidDevice class and include all your device related commands in the new class (see example app)

Usage

You need to setup repositories to use github packages (see example app):

    repositories {
        google()
        mavenCentral()
        maven {
            name = "GitHubPackages"
            url = uri("https://maven.pkg.github.com/siqneibi/UsbHid")

            credentials {
                /**Create github.properties in root project folder file with gpr.usr=GITHUB_USER_ID  & gpr.key=PERSONAL_ACCESS_TOKEN**/
                username = githubProperties['gpr.usr']
                password = githubProperties['gpr.key']
            }
        }
    }

And add following line to dependencies section:

implementation 'co.sedco:usbhid:0.3.0'

QuickStart

Create a connection handler in your activity

    private val mConnectionHandler: IUsbConnectionHandler = object :
        IUsbConnectionHandler {
        override fun onDeviceConnected() {
            Log.d(TAG,"onDeviceConnected")
        }
        override fun onDeviceDisconnected() {
            Log.d(TAG,"onDeviceDisconnected")
        }
        override fun onDeviceNotFound() {
            Log.d(TAG,"onDeviceNotFound")
        }
        override fun onDevicePermissionDenied() {
            Log.d(TAG,"onDevicePermissionDenied")
        }
    }

Extend the the UsbHidDevice class with your own custom behavior

class CustomHidDevice(appContext: Context, connectionHandler: IUsbConnectionHandler): UsbHidDevice(appContext, connectionHandler, MyVendorId, MyProductId) {

And finally instantiate the CustomHidDevice class in your activity and communicate with your HID device

    hidDevice = CustomHidDevice(application.applicationContext, mConnectionHandler)
    hidDevice.setDevice(DEVICE_LED1, DEVICE_BLINK)
    val (result, value) = hidDevice.getDevice(DEVICE_SENSOR1)
    

For details, please see example application.
