Question

我最近在华为Mate 9设备上安装了Android 9.0。在安装Android 8之前，BluetoothDevice.setPin一直运行良好。有什么线索为什么这不再起作用了？

public class BlututReceiver extends BroadcastReceiver {
        private final static byte[] PIN = "0000".getBytes();

        public void onReceive(android.content.Context r7, android.content.Intent intent) {
            BluetoothDevice bluetoothDevice = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
            String action = intent.getAction();
            if (BluetoothDevice.ACTION_PAIRING_REQUEST.equals(action)) {
                sendPin(bluetoothDevice);
            }
        }

        private void sendPin(BluetoothDevice bluetoothDevice) {
            try {
                Thread.sleep(100);
                bluetoothDevice.setPin(PIN);
                bluetoothDevice.createBond();
                //bluetoothDevice.setPairingConfirmation(true);
                //bluetoothDevice.getClass().getMethod("setPairingConfirmation", new Class[]{Boolean.TYPE}).invoke(bluetoothDevice, new Object[]{Boolean.valueOf(true)});
            } catch (Exception e) {
                Log.e("BLUETOOTHSETPINERR",e.getMessage());
            }
        }
    }




<receiver android:name=".Utile.BlututReceiver">
            <intent-filter android:priority="1000">
                <action android:name="android.bluetooth.device.action.PAIRING_REQUEST" />
            </intent-filter>
        </receiver>

它在带有Android Pie的Xiaomi Mi 9中正常工作。看来这是华为的问题。我尝试使用HUAWEI P10和HUAWEI PSMART（两者都使用Android Pie），但无法正常工作。
