The following code sample shows you how to use the onBondStateChanged() method:

<code class="java">private BluetoothGattCallback gattCallback = new BluetoothGattCallback() {
    @Override
    public void onBondStateChanged(BluetoothDevice device, int bondState, int previousBondState) {
        super.onBondStateChanged(device, bondState, previousBondState);
        String bondStateString = "Unknown bond state";
        switch (bondState) {
            case BluetoothDevice.BOND_NONE:
                bondStateString = "BOND_NONE";
                break;
            case BluetoothDevice.BOND_BONDING:
                bondStateString = "BOND_BONDING";
                break;
            case BluetoothDevice.BOND_BONDED:
                bondStateString = "BOND_BONDED";
                break;
        }
        String previousBondStateString = "Unknown bond state";
        switch (previousBondState) {
            case BluetoothDevice.BOND_NONE:
                previousBondStateString = "BOND_NONE";
                break;
            case BluetoothDevice.BOND_BONDING:
                previousBondStateString = "BOND_BONDING";
                break;
            case BluetoothDevice.BOND_BONDED:
                previousBondStateString = "BOND_BONDED";
                break;
        }
        Log.d(TAG, "onBondStateChanged() - Device: " + device + "  Bond State: " + bondStateString + "  Previous Bond State: " + previousBondStateString);
    }
};</code>
