How to implement Android Bluetooth development automatic pairing connection, do not pop up the prompt box

Before making an Android version of Bluetooth, the biggest challenge is to automatically pair.

Surfing the internet for information says it is using reflex createbond () and Setpin (), but pairing or prompting when testing, but pairing is successful.

I started to find out how to close this Bluetooth pairing prompt box, behind the great Android source help me.

There are two hidden methods in the source Bluetoothdevice class.

Cancelbondprocess () and Cancelpairinguserinput ()

One of the two methods is to cancel the pairing process one is to cancel the user input

Here is the code for auto pairing
