Answer 1

With version 8.3.0 of the Play Services the messages could be delayed up to 30 minutes. With the new setUrgent() method it is send without a delay.

Finally, if you are developing for wearables, you’ll know that battery life and optimization of power usage are critical in having a great user experience. With Google Play services 8.3, we’ve updated the DataApi to allow for urgency in how data items are synced. Now, a priority can be added to the data item to determine when it should be synced. For example, if you are building an app that requires immediate syncing, such as a remote control app, it can still be done immediately by calling setUrgent(), but for something such as updating your contacts, you could tolerate some delay. Non-urgent DataItems may be delayed for up to 30 minutes, but you can expect that in most cases they will be delivered within a few minutes. Low priority is now the default, so setUrgent() is needed to obtain the previous timing.
