Custom Activity class in a Cordova app?

Question

Is it possible to make a Cordova app use a custom subclass of CordovaActivity?

This question was originally about detecting arbitrary key events in a Cordova app. But now I think this is impossible for the same reason it's impossible to receive key events in a Service. However, I'm thinking that if I could extend CordovaActivity, I could override the onKey... methods and broadcast something on the LocalBroadcastManager, which could be received by a plugin.

I'm trying to capture the KEYCODE_HEADSETHOOK that is generated from an audio jack phone handset. We tried listening for the onkey... events in JavaScript. No dice. Since neither CordovaActivity nor CordovaWebView overrides any of the onKey... methods, I don't know if or how the JavaScript receives any key events at all.

If you want communication between native and JS you will need to create a plugin. — Dawson Loudon, Mar 25 '15 at 20:02
@DawsonLoudon I explored that avenue. Plugins cannot override methods in the `Activity` or `WebView`, and I don't know of any other way to intercept the key events. — Kevin Krumwiede, Mar 25 '15 at 20:06
In other words, a plugin cannot listen for key presses for the same reason [a Service cannot](http://stackoverflow.com/questions/2986337/is-it-possible-to-create-an-android-service-that-listens-for-hardware-key-presse). — Kevin Krumwiede, Mar 25 '15 at 20:09
which key presses are you looking for? I think it was originally in the question, but I don't see it now. — Dawson Loudon, Mar 25 '15 at 21:51
I was able to use my headphone volume buttons using the cordova events `volumeupbutton` and `volumedownbutton` but the play/pause button did nothing. — Dawson Loudon, Mar 25 '15 at 22:18
I'd like to know what somebody thinks is "opinion-based" about this question. — Kevin Krumwiede, Mar 26 '15 at 20:37

According to an "Official Rep" in the PhoneGap community forums, this was not possible as of July 2012.
