Bug in Android Mobile Interface

My Drew's Intervals app is no longer able to receive workouts from its Android helper application.

On investigating this further I note that there is no longer a callback from getApplicationInfo.  I also note that this is an issue from around 5 yrs ago.  I also note the more recent re-emergence of this problem.

This part of Garmin's mobile SDK is pretty shabby.  Garmin's documentation was incorrect describing a synchronous model.  Thankfully Android Studio allowed reverse engineering of the java library with method signatures so I was able to work out what was going on.

You now seem to have broken it. 

Is this an undocumented change from the previous incorrectly documented SDK?
