How can I avoid or dismiss Android's Bluetooth pairing notification when I am doing programmatic pairing?

Question

I have an app where I am programmatically controlling Bluetooth pairing and unpairing. I can pair before connection and unpair afterwards. The reason I need to do this is

Answer 1

Since Android API 19 Google switched these Methods to public Methods, so there is no need for Reflection any more. :)

Answer 2

Do this in the PAIRING_REQUEST notification event:

BluetoothDevice localBluetoothDevice = (BluetoothDevice)intent.getParcelableExtra("android.bluetooth.device.extra.DEVICE");

Class localClass = localBluetoothDevice.getClass();
Class[] arrayOfClass = new Class[0];
localClass.getMethod("cancelPairingUserInput", arrayOfClass).invoke(paramBluetoothDevice, null)).booleanValue();

But you gotta tell me how did you pair your remote device without the user to enter Passkey/PIN? off course, you know the PIN for the remote device which is trying to pair to your device but how did you provide that PIN to the remote device.

Answer 3

Try setting the confirmation first in the PAIRING_REQUEST

BluetoothDevice device = intent.getParcelableExtra("android.bluetooth.device.extra.DEVICE");

device.getClass().getMethod("setPairingConfirmation", boolean.class).invoke(device, true);
device.getClass().getMethod("cancelPairingUserInput").invoke(device);

This worked for me between two Android devices using RFCOMM but I'm not entering any PINs
