A [DataItem][2] is synchronized across all devices in an Android Wear network. 79It is possible to set data items while not connected to any nodes. Those data items will be synchronized 80when the nodes eventually come online. 81 82This example presents three buttons that would trigger three different combinations of 83notifications on the handset and the watch: 84 851. The first button builds a simple local-only notification on the handset. 862. The second one creates a wearable-only notification by putting a data item in the shared data 87store and having a [com.google.android.gms.wearable.WearableListenerService][3] listen for 88that on the wearable. 893. The third one creates a local notification and a wearable notification by combining the above 90two. It, however, demonstrates how one can set things up so that the dismissal of one 91notification results in the dismissal of the other one. 92 93In the #2 and #3 items, the following code is used to synchronize the data between the handheld 94and the wearable devices using DataAPI. 95 96```java 97PutDataMapRequest putDataMapRequest = PutDataMapRequest.create(path); 98putDataMapRequest.getDataMap().putString(Constants.KEY_CONTENT, content); 99putDataMapRequest.getDataMap().putString(Constants.KEY_TITLE, title); 100PutDataRequest request = putDataMapRequest.asPutDataRequest(); 101Wearable.DataApi.putDataItem(mGoogleApiClient, request) 102 .setResultCallback(new ResultCallback<DataApi.DataItemResult>() { 103 @Override 104 public void onResult(DataApi.DataItemResult dataItemResult) { 105 if (!dataItemResult.getStatus().isSuccess()) { 106 Log.e(TAG, "buildWatchOnlyNotification(): Failed to set the data, " 107 + "status: " + dataItemResult.getStatus().getStatusCode()); 108 } 109 } 110 }); 111``` 112 113[1]: http://developer.android.com/reference/com/google/android/gms/wearable/DataApi.html#putDataItem(com.google.android.gms.common.api.GoogleApiClient%2C%20com.google.android.gms.wearable.PutDataRequest) 114[2]: http://developer.android.com/reference/com/google/android/gms/wearable/DataItem.html 115[3]: https://developer.android.com/reference/com/google/android/gms/wearable/WearableListenerService.html 116]]> 117 </intro> 118 </metadata> 119</sample> 120
