Android SynchronizedNotifications Sample

A basic sample showing how to use simple or synchronized notifications. This allows users to dismiss events from either their phone or wearable device simultaneously.


The DataAPI exposes an API for components to read or write data items and assets between the handhelds and wearables. A DataItem is synchronized across all devices in an Android Wear network. It is possible to set data items while not connected to any nodes. Those data items will be synchronized when the nodes eventually come online.

This example presents three buttons that would trigger three different combinations of notifications on the handset and the watch:

  1. The first button builds a simple local-only notification on the handset.
  2. The second one creates a wearable-only notification by putting a data item in the shared data store and having a listen for that on the wearable.
  3. The third one creates a local notification and a wearable notification by combining the above two. It, however, demonstrates how one can set things up so that the dismissal of one notification results in the dismissal of the other one.

In the #2 and #3 items, the following code is used to synchronize the data between the handheld and the wearable devices using DataAPI.

PutDataMapRequest putDataMapRequest = PutDataMapRequest.create(path);
putDataMapRequest.getDataMap().putString(Constants.KEY_CONTENT, content);
putDataMapRequest.getDataMap().putString(Constants.KEY_TITLE, title);
PutDataRequest request = putDataMapRequest.asPutDataRequest();
Wearable.DataApi.putDataItem(mGoogleApiClient, request)
        .setResultCallback(new ResultCallback<DataApi.DataItemResult>() {
            public void onResult(DataApi.DataItemResult dataItemResult) {
                if (!dataItemResult.getStatus().isSuccess()) {
                    Log.e(TAG, "buildWatchOnlyNotification(): Failed to set the data, "
                            + "status: " + dataItemResult.getStatus().getStatusCode());
