This is NOT an officially supported Google product.

Usage

List Attached Fastboot Devices

// Includes connected devices.
val deviceIds : List<DeviceId> = FastbootDeviceManager.getAttachedDeviceIds()

List Connected Fastboot Devices

val deviceIds : List<DeviceId> = FastbootDeviceManager.getConnectedDeviceIds()

Connect to a Fastboot Device

// typealias DeviceId = String
FastbootDeviceManager.addFastbootDeviceManagerListener(
    object : FastbootDeviceManagerListener() {
        override fun onFastbootDeviceAttached(deviceId: DeviceId) {
            Log.d("Device attached: $deviceId")
        }

        override fun onFastbootDeviceDetached(deviceId: DeviceId) {
            Log.d("Device detached: $deviceId")
        }

        override fun onFastbootDeviceConnected(deviceId: DeviceId, deviceContext: FastbootDeviceContext) {
            // Do some fastboot stuff...
            val response = deviceContext.sendCommand(FastbootCommand.getVar("current-slot"))
            val bootSlot = response.data
            Log.d("Device $deviceId with slot $bootSlot.")
        }
    })

FastbootDeviceManager.connectToDevice(/* Serial Number */ "abc123")
