Unless explicitly annotated, parameters in java are by default nullable. There are a few cases where a null context may be passed to the unregisterReceiverSafely function of SimpleBroadcastReceiver. To mitigate misuses or incorrect contexts being passed for register vs unregister, keep the context as a strong reference in the constructor. Also added NonNull annotations for any public callsites to enforce behavior.
