1 2 Android SynchronizedNotifications Sample 3 =================================== 4 5 A basic sample showing how to use simple or synchronized notifications. 6 This allows users to dismiss events from either their phone or wearable device simultaneously. 7 8 Introduction 9 ------------ 10 11 The [DataAPI][1] exposes an API for components to read or write data items and assets between 12 the handhelds and wearables. A [DataItem][2] is synchronized across all devices in an Android Wear network. 13 It is possible to set data items while not connected to any nodes. Those data items will be synchronized 14 when the nodes eventually come online. 15 16 This example presents three buttons that would trigger three different combinations of 17 notifications on the handset and the watch: 18 19 1. The first button builds a simple local-only notification on the handset. 20 2. The second one creates a wearable-only notification by putting a data item in the shared data 21 store and having a [com.google.android.gms.wearable.WearableListenerService][3] listen for 22 that on the wearable. 23 3. The third one creates a local notification and a wearable notification by combining the above 24 two. It, however, demonstrates how one can set things up so that the dismissal of one 25 notification results in the dismissal of the other one. 26 27 In the #2 and #3 items, the following code is used to synchronize the data between the handheld 28 and the wearable devices using DataAPI. 29 30 ```java 31 PutDataMapRequest putDataMapRequest = PutDataMapRequest.create(path); 32 putDataMapRequest.getDataMap().putString(Constants.KEY_CONTENT, content); 33 putDataMapRequest.getDataMap().putString(Constants.KEY_TITLE, title); 34 PutDataRequest request = putDataMapRequest.asPutDataRequest(); 35 Wearable.DataApi.putDataItem(mGoogleApiClient, request) 36 .setResultCallback(new ResultCallback<DataApi.DataItemResult>() { 37 @Override 38 public void onResult(DataApi.DataItemResult dataItemResult) { 39 if (!dataItemResult.getStatus().isSuccess()) { 40 Log.e(TAG, "buildWatchOnlyNotification(): Failed to set the data, " 41 + "status: " + dataItemResult.getStatus().getStatusCode()); 42 } 43 } 44 }); 45 ``` 46 47 [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) 48 [2]: http://developer.android.com/reference/com/google/android/gms/wearable/DataItem.html 49 [3]: https://developer.android.com/reference/com/google/android/gms/wearable/WearableListenerService.html 50 51 Pre-requisites 52 -------------- 53 54 - Android SDK 24 55 - Android Build Tools v24.0.1 56 - Android Support Repository 57 58 Screenshots 59 ------------- 60 61 <img src="screenshots/different_notifications_phone.png" height="400" alt="Screenshot"/> <img src="screenshots/different_notifications_wearable.png" height="400" alt="Screenshot"/> <img src="screenshots/notification_options.png" height="400" alt="Screenshot"/> <img src="screenshots/watch_only_notification.png" height="400" alt="Screenshot"/> 62 63 Getting Started 64 --------------- 65 66 This sample uses the Gradle build system.
