Question

我正在玩可穿戴设备，我已经从我的微应用程序（在可穿戴设备上运行）with some little restrictions创建了通知，我想知道如何创建待处理的意图在手机上打开主应用程序。

Answer 1

我不知道是否还有其他办法。

然而它可以工作。您在磨损模块中构建通知，即可在磨损中启动广播。广播（在磨损上运行）使用 Message.API 向移动模块发送消息。在移动模块上有一个 WearableListenerService ，可在移动设备上启动MainActivity。

在穿着中构建通知：

 // Notification
        NotificationCompat.Builder notificationBuilder =
                new NotificationCompat.Builder(this)
                        .setSmallIcon(R.drawable.ic_launcher)
                                //.setContentTitle(mNotificationUtil.getTitle())
                        .setContentText("Text")
                        .setContentIntent(getPendingIntent(this));

        // Get an instance of the NotificationManager service
        NotificationManagerCompat notificationManager =
                NotificationManagerCompat.from(this);

        // Build the notification and issues it with notification manager.
        notificationManager.notify(1, notificationBuilder.build());

    }

    private PendingIntent getPendingIntent(MainActivity mainActivity) {
        final String INTENT_ACTION = "it.gmariotti.receiver.intent.action.TEST";

        Intent intent = new Intent();
        intent.setAction(INTENT_ACTION);
        PendingIntent pendingIntent =
                PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

        return pendingIntent;
    }

此通知启动广播消息。在你的wear / AndroidManifest.xml

中声明这个广播

<强>穿/ AndroidManifes.xml

<meta-data android:name="com.google.android.gms.version" 
          android:value="@integer/google_play_services_version" />


 <receiver android:name=".MyBroadcast">
         <intent-filter>
              <action android:name="it.gmariotti.receiver.intent.action.TEST"/>
         </intent-filter>
 </receiver>

然后实施广播以发送消息：

public class MyBroadcast extends BroadcastReceiver implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {

    Node mNode; // the connected device to send the message to
    GoogleApiClient mGoogleApiClient;
    private static final String WEAR_PATH = "/hello-world-wear";

    @Override
    public void onReceive(Context context, Intent intent) {

        //Connect the GoogleApiClient
        mGoogleApiClient = new GoogleApiClient.Builder(context)
                .addApi(Wearable.API)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .build();

        mGoogleApiClient.connect();
    }
    /**
     * Send message to mobile handheld
     */
    private void sendMessage() {

        if (mNode != null && mGoogleApiClient!=null && mGoogleApiClient.isConnected()) {
            Wearable.MessageApi.sendMessage(
                    mGoogleApiClient, mNode.getId(), WEAR_PATH, null).setResultCallback(

                    new ResultCallback<MessageApi.SendMessageResult>() {
                        @Override
                        public void onResult(MessageApi.SendMessageResult sendMessageResult) {

                            if (!sendMessageResult.getStatus().isSuccess()) {
                                Log.e("TAG", "Failed to send message with status code: "
                                        + sendMessageResult.getStatus().getStatusCode());
                            }
                        }
                    }
            );
        }else{
            //Improve your code
        }

    }

    /*
     * Resolve the node = the connected device to send the message to
     */
    private void resolveNode() {

        Wearable.NodeApi.getConnectedNodes(mGoogleApiClient).setResultCallback(new ResultCallback<NodeApi.GetConnectedNodesResult>() {
            @Override
            public void onResult(NodeApi.GetConnectedNodesResult nodes) {
                for (Node node : nodes.getNodes()) {
                    mNode = node;
                }
                sendMessage();
            }
        });
    }


    @Override
    public void onConnected(Bundle bundle) {
        resolveNode();
    }

    @Override
    public void onConnectionSuspended(int i) {
        //Improve your code
    }

    @Override
    public void onConnectionFailed(ConnectionResult connectionResult) {
        //Improve your code
    }
}

此代码会向您的手机发送消息。它需要在 wear / build.gradle

中

dependencies {
    compile "com.google.android.support:wearable:1.0.+"
    compile 'com.google.android.gms:play-services-wearable:+'
}

在**移动模块上，您必须实施WearableListenerService **

/**
 * @author Gabriele Mariotti (gabri.mariotti@gmail.com)
 */
public class ListenerServiceFromWear extends WearableListenerService {

    private static final String WEAR_PATH = "/hello-world-wear";

    @Override
    public void onMessageReceived(MessageEvent messageEvent) {

        /*
         * Receive the message from wear
         */
        if (messageEvent.getPath().equals(WEAR_PATH)) {

            Intent startIntent = new Intent(this, MainActivity.class);
            startIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(startIntent);
        }    
    }    
}

您需要在 Mobile / AndroidManifest.xml 中声明服务。

<service android:name=".ListenerServiceFromWear">
            <intent-filter>
                <action android:name="com.google.android.gms.wearable.BIND_LISTENER" />
            </intent-filter>
        </service>

以及 mobile / build.gradle 依赖关系：

dependencies {
    wearApp project(':wear')
    compile 'com.google.android.gms:play-services-wearable:+'
}

Answer 2

我刚刚测试过的解决方案，它可以在Android应用程序上添加一个消息监听器，只需从可穿戴设备发送我想要它的详细信息。

public class WearMessagesAPI_Service
        extends WearableListenerService {


    private static final String OPEN_APP_PATH = "/OpenApp";

    @Override
    public void onMessageReceived(MessageEvent event) {
        Log.w("WearMessagesAPI_Service", event.getPath());
        String activityKey = new String(event.getData());
        if(activityKey.equals(...)) {
            Intent myAppIntent = ... create intent ...
            startActivity(myAppIntent);
        }
    }
}

不要忘记将它添加到您的清单中：

<service android:name=".wearable.WearMessagesAPI_Service">
    <intent-filter>
        <action android:name="com.google.android.gms.wearable.BIND_LISTENER"/>
    </intent-filter>
</service>

我相信就是这样。让我知道它是怎么回事:)）
