Answer 1

Before you call the following method

!mBluetoothAdapter.isEnabled()

on the adapter, you have to make sure mBluetoothAdapter is not null. In your case it must be null and crashing. And if mBluetoothAdapter is null, the android documentation says that the device doesn't support Bluetooth.
