I have a wrapper class (BluetoothDiscoverer) which is instantiated within a Service. This class obtains a BluetoothAdapter and checks whether Bluetooth is enabled before scanning for neighbouring devices.
Now if Bluetooth is not enabled I want to be able to do the following within this class (BluetoothDiscoverer):
Intent enableBluetoothIntent = new
Now I have read this: use startActivityForResult from non-activity
but I don't want to pass my Main Activity into this object since I want to deal with the result (whether the user accepts to enable bluetooth or not) within the BluetoothDiscoverer class.
Now If I make BluetoothDiscoverer a subclass of Activity
I seem to be getting a NullPointerException when the startActivityForResult is about to be called.
I think this is because I need to add an onCreate()/onDestroy() method, but this defeats the purpose of what I am doing as I need to be able to call methods on the BluetoothDiscoverer object within the service that instantiates this class.
I also need to register a broadcast receiver for retrieving neighbouring devices when a scan is initiated. If the BluetoothDiscoverer class is not an Activity, how do I register this receiver?
Is there a work around for this?
