WearableListenerService, onDataChanged() is not called

Question

I followed the tutorial to invoke a Wearable activity from phone, posted here How to send notification from handheld to wear to open Activity on wear device. However, I grab

Answer 1

1.check build.gradle for mobile and for wear to have the same play version compile 'com.google.android.gms:play-services-wearable:6.5.87'

Mine has a + sign on mobile and it took the last version on mobile only

Upgrade same version on both until it works

2.Stupid workaround, if nothing works (!! this works with different play versions on pairs, if you do step one you do not need this)

....
Wearable.DataApi.putDataItem(mGoogleApiClient, request)
.......  
this line after your put

Wearable.DataApi.deleteDataItems(mGoogleApiClient, request.getUri());

It is a replication trick that do 3 things :

• wake up pair

• send data

• execute OnDataChange on both with good data

• delete data (execute OnDataChange on both with no data) (so prepare to work even after the data was deleted)

My problem was that data was queued and paused on watch until first touch - now it is real time bidirectional
