Android: Not receive event for UsbManager.ACTION_USB_DEVICE_DETACHED status

Question

I'm currently facing an issue in my Android app related to USB device detachment. I have a screen (SetupPrinterActivity) that is supposed to open when a USB device is attached and detached. The attachment part is working fine, but the detachment isn't triggering the expected behavior.

Here's a snippet from AndroidManifest.xml:

            <meta-data
                android:name="android.hardware.usb.action.USB_DEVICE_DETACHED"

        </activity>

    </application>

</manifest>

The USB attachment works as expected, and SetupPrinterActivity opens. However, when detaching the USB device from another screen, the expected behavior does not occur.

Here's a snippet from my SetupPrinterActivity.xml:

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    initReceiver()
}

private fun initReceiver() {
    // Create a BroadcastReceiver for USB events
    usbReceiver = object : BroadcastReceiver() {
        override fun onReceive(context: Context?, intent: Intent?) {
            Log.i(tag, "onReceive usbReceiver")
            try {
                when (intent?.action) {
                    UsbManager.ACTION_USB_DEVICE_ATTACHED -> {
                        // USB device attached
                        Log.i("CHKI", "onReceive usbReceiver ACTION_USB_DEVICE_ATTACHED")
                        val device: UsbDevice? = intent.getParcelableExtra(UsbManager.EXTRA_DEVICE)
                        Log.d(tag, "USB RECEIVER Attached: ${device?.deviceName}")

                        if (device != null) {
                            onUSBAttach(device.deviceName)
                        }
                    }
                    UsbManager.ACTION_USB_DEVICE_DETACHED -> {
                        // USB device detached
                        Log.i("CHKI", "onReceive usbReceiver ACTION_USB_DEVICE_DETACHED")
                        val device: UsbDevice? = intent.getParcelableExtra(UsbManager.EXTRA_DEVICE)
                        Log.d(tag, "USB RECEIVER Detached: ${device?.deviceName}")

                        if (device != null) {
                            onUSBDetach(device.deviceName)
                        }
                    }
                }
            } catch (e: Exception) {
                Log.e("CHKI", "Exception in BroadcastReceiver onReceive: ${e.message}")
                e.printStackTrace()
            }
        }
    }

    // Register the BroadcastReceiver with the intent filters
    val filter = IntentFilter().apply {
        addAction(UsbManager.ACTION_USB_DEVICE_ATTACHED)
        addAction(UsbManager.ACTION_USB_DEVICE_DETACHED)
    }
    registerReceiver(usbReceiver, filter)
}

Here's the current behavior of my app:

• When I attach a USB device from another screen, the app opens the SetupPrinterActivity and calls the onCreate method, which is the expected behavior.

Now, here's what I'm expecting for USB detachment:

• Similar to USB attachment, when I detach the USB device from another screen, I expect the app to open the SetupPrinterActivity and call the onCreate method. However, this behavior is not currently happening.

Behavior of Broadcast receiver:

• Broadcast receiver callbacks (attach USB and detach USB) only works when when the SetupPrinterActivity is open, otherwise calls the onCreate method if it is closed.

Has anyone faced a similar issue before, where USB detachment does not trigger the expected behavior. Please help me and Thanks in advance for read my issue.
