(assuming this is related to the NPE I am seeing in [1])

I think the ultimate goal for 2.2.0 should be to to not crash like in [1].

I see three options:
1) document the work-around ([2]) and release the _existing_ 2.2.0, as is
-> The fact that the work-around needs to be added to (almost) all apps,
makes it an odd work-around (not saying it's a no-go)
2) delay the 2.2.0 and get full GCM 3.0 support in there
-> IMO it's unknown how long that takes, and ideally our 2.2.0 AGDroid-Push
should be out once we have the UPS released (early July); This also could
mean a delay on our Cordova lib.
3) Update 2.2.0 to ignore the ACK sent from GCM 3.0, and get a 2.2.x (or
2.3.0) a bit later for full support on GCM 3.0
-> IMO this allows us to release UPS 1.1.0 (and AGDroid-Push) in a
reasonable timeframe and moves the work-around into our library, and not
onto all the app developers.


My vote would be going w/ option #3, given the above reasoning and the fact
that we don't use any GCM 3.0 feature atm, it sounds fairly safe (at least
to me) doing the working inside of our library
