About Android reflection Bluetooth paring

I am developing a apps using reflection to make bluetooth device paring.

device.getClass().getMethod("createBond", (Class[]) null).invoke(device, (Object[]) null);

This code is work fine, but for our requirement, we need to custom the system pairing dialog / skip the pop up system pairing dialog.

So How Can I Pairing Up Device With Out System Pop Up Dialog? Or Custom That Pop Up Dialog?

Thanks all.
