Intent.hasExtra(UsbManager.EXTRA_PERMISSION_GRANTED); всегда возвращает ложь ⇐ JAVA

[Anonymous]

у меня простая настройка

Код: Выделить всё

private final BroadcastReceiver m_usbReceiver = new BroadcastReceiver()
{
@Override
public void onReceive(final Context context, final Intent intent)
{
try {
final IBScan ibScan = IBScan.m_instance;
final String action = intent.getAction();

ibScan.getDeviceCount();

/* Receive event about device attachment. */
if (action.equals(UsbManager.ACTION_USB_DEVICE_ATTACHED)) {
NativeLogger.log("ACTION_USB_DEVICE_ATTACHED");
UsbDevice device = (UsbDevice) intent.getParcelableExtra(UsbManager.EXTRA_DEVICE);
if (device != null) {
final boolean isScanDevice = isScanDevice(device);
if (isScanDevice) {
callbackScanDeviceAttached(device.getDeviceId());
}
}
}

/* Receive event about device detachment. */
else if (action.equals(UsbManager.ACTION_USB_DEVICE_DETACHED)) {
NativeLogger.log("ACTION_USB_DEVICE_DETACHED");
UsbDevice device = (UsbDevice) intent.getParcelableExtra(UsbManager.EXTRA_DEVICE);
if (device != null) {
final boolean isScanDevice = isScanDevice(device);
if (isScanDevice) {
callbackScanDeviceDetached(device.getDeviceId());
}
}
}

/* Receive event about access permission granted or denied. */
else if (action.equals(ACTION_USB_PERMISSION)) {
NativeLogger.log("ACTION_USB_PERMISSION received.");
final boolean exists = intent.hasExtra(UsbManager.EXTRA_PERMISSION_GRANTED); // always false
NativeLogger.log("EXTRA_PERMISSION_GRANTED exists: " + exists);

if (exists) {
final boolean granted = intent.getBooleanExtra(UsbManager.EXTRA_PERMISSION_GRANTED, false);
NativeLogger.log("Permission granted: " + granted);

final UsbDevice device = (UsbDevice) intent.getParcelableExtra(UsbManager.EXTRA_DEVICE);
if (device != null) {
NativeLogger.log("Device found: " + device.getDeviceName());
if (isScanDevice(device)) {
NativeLogger.log("Device is a scan device.");
callbackScanDevicePermissionGranted(device.getDeviceId(), granted);
} else {
NativeLogger.log("Device is not a scan device.");
}
} else {
NativeLogger.log("Device is null in intent.");
}
} else {
NativeLogger.log("EXTRA_PERMISSION_GRANTED key is missing. Retrying...");
}
}
} catch (IBScanException ibse) {
ibse.printStackTrace();
}
}
};

И вот как я запрашиваю разрешения:

Код: Выделить всё

public void requestPermission(final int deviceId) {
/* Request permission with the USB manager. */
final UsbDevice device = findDevice(deviceId);
if (device != null) {
NativeLogger.log("Requesting permission for device: " + device.getDeviceName());

/* Create intent and request permission with the USB manager. */
final UsbManager manager = (UsbManager) this.m_context.getSystemService(Context.USB_SERVICE);

if (manager == null) {
NativeLogger.log("UsbManager is null.  Cannot request permission.");
return;
}

final Intent intent = new Intent(ACTION_USB_PERMISSION);
final PendingIntent permissionIntent;

if (Build.VERSION.SDK_INT >= 23) {
// Create a PendingIntent using FLAG_IMMUTABLE.
permissionIntent = PendingIntent.getBroadcast(this.m_context, 0, intent,
PendingIntent.FLAG_CANCEL_CURRENT | PendingIntent.FLAG_IMMUTABLE);
} else {
// Existing code that creates a PendingIntent.
permissionIntent = PendingIntent.getBroadcast(this.m_context, 0, intent, PendingIntent.FLAG_IMMUTABLE);
}

NativeLogger.log("PendingIntent created for USB permission: " + intent.getAction());
manager.requestPermission(device, permissionIntent);
} else {
NativeLogger.log("Device not found for deviceId: " + deviceId);
}
}

Это нативное приложение. Я пытаюсь создать мостовой модуль, не уверен, что делаю неправильно, что-нибудь поможет. спасибо
