I am reusing some of the classes from the FindMyPhone demo for Android Wear https://github.com/mauimauer/AndroidWearable-Samples/tree/master/FindMyPhone
I am trying to send a message to the handheld app but only after the user has pressed the launcher on their watch 5 times. If I set the trigger to true for the first run it will work. But when I use the counter to set trigger true after 5 runs I see the log output

UPDATE
I think the problem is the listener is looking for an update to the data map but there is no update happening. So maybe trigger an update? Maybe add a timestamp field?
