Notifications on Android

[rgstephens]

I'm trying to get notifications of a button press on a cheap key fob. The subscribe works but I don't receive any notifications. It looks like I need to also enable notifications or set the client configuration descriptor but I'm confused about this additional step.

It looks from the source code like the enable notification call is being made in the subscribeAction call.

I also see references, like in #218, that I need to set the Client Configuration Descriptor. What does this call look like?

Update

I think I'm running into a problem that's particular to the iTag fob and described here. I'm going to test with another fob to confirm before closing this issue.

You should just have to call subscribe. There may be an issue with subscribe on some devices, which this PR may resolve. You could try merging this locally and seeing if it works. I'm hesitant to merge that PR since I'm not sure how it will affect everyone else.
