在BIND_LISTENER弃用后无法接收数据

Question

我的应用程序一直运行良好，直到BIND_LISTENER不推荐，我已经做了任何必要的改变，但我的应用程序不工作。我成功地发送了来自磨损的数据，但电话侧没有发生任何事情。

我的主要密码是穿(发件人)：

public class MainActivity extends Activity implements
    GoogleApiClient.ConnectionCallbacks,
    GoogleApiClient.OnConnectionFailedListener {

private TextView mTextView;
GoogleApiClient googleClient;
String WEARABLE_DATA_PATH = "/wearable_data";
ArrayList<String> dataBlock = new ArrayList();
Button startButton;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    final WatchViewStub stub = (WatchViewStub) findViewById(R.id.watch_view_stub);
    stub.setOnLayoutInflatedListener(new WatchViewStub.OnLayoutInflatedListener() {
        @Override
        public void onLayoutInflated(WatchViewStub stub) {
            mTextView = (TextView) stub.findViewById(R.id.text);
        }
    });


    startButton = (Button) findViewById(R.id.startButton);
    // Build a new GoogleApiClient that includes the Wearable API
    googleClient = new GoogleApiClient.Builder(this)
            .addApi(Wearable.API)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .build();
}
@Override
public void onConnected(Bundle connectionHint) {
    Log.v("CONNECTED", "CONNECTED");
    DataMap map = new DataMap();
    map.putLong("Time",System.currentTimeMillis());
    new SendToDataLayerThread(WEARABLE_DATA_PATH, map).start();
}

public void onStartClicked(View view) {
    Log.v("StartClicked", "in on start clicked");
    googleClient.connect();
}
@Override
public void onConnectionSuspended(int cause) {
    Log.v("Suspended", "Suspended");

}

@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
    Log.v("Failed", "onConnectionFailed: ConnectionResult.getErrorCode() = "
            + connectionResult.getErrorCode());
}


class SendToDataLayerThread extends Thread {
    String path;
    DataMap dataMap;


    // Constructor for sending data objects to the data layer
    SendToDataLayerThread(String p, DataMap data) {
        path = p;
        dataMap = data;
    }

    public void run() {
        // Construct a DataRequest and send over the data layer
        PutDataMapRequest putDMR = PutDataMapRequest.create(path);
        putDMR.getDataMap().putAll(dataMap);
        putDMR.setUrgent();
        PutDataRequest request = putDMR.asPutDataRequest();
        DataApi.DataItemResult result = Wearable.DataApi.putDataItem(googleClient, request).await();
        if (result.getStatus().isSuccess()) {
            Log.v("myTag", "DataMap: " + dataMap + " sent successfully to data layer ");
        }
        else {
            // Log an error
            Log.v("myTag", "ERROR: failed to send DataMap to data layer");
        }
    }
}
protected void onPause() {
    super.onPause();
}
@Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {

}
protected void onResume() {
    super.onResume();
}
@Override
protected void onStart() {
    super.onStart();
}
}

我的着装宣言：

        </intent-filter>
    </activity>

电话端的侦听器服务：

public class ListenerService extends WearableListenerService {
//private static final String START_ACTIVITY_PATH = "/start-activity";
private static final String WEARABLE_DATA_PATH = "/wearable_data";

public void onMessageReceived(MessageEvent messageEvent) {
    Log.v("myTag", "Test");
}

public void onDataChanged(DataEventBuffer dataEvents) {
    DataMap dataMap;
    Log.v("myTag", "DataMap received from watch: ");
    for (DataEvent event : dataEvents) {

        // Check the data type
        if (event.getType() == DataEvent.TYPE_CHANGED) {
            // Check the data path
            String path = event.getDataItem().getUri().getPath();
            if (path.equals(WEARABLE_DATA_PATH)) {}
            dataMap = DataMapItem.fromDataItem(event.getDataItem()).getDataMap();
            Log.v("myTag", "DataMap received on watch: " + dataMap);
        }
    }
}
}

Answer 1

当我不得不停止使用绑定侦听器时，我也遇到了同样的情况。手机没有收到任何信息，因为你的手机清单上有android:exported="false"。要么删除它，要么将其设置为true，您应该能够再次接收数据。

编辑：您也错过了电话清单中的路径。您正在使用path /wearable_data将消息发送到电话，但是它将永远不会接收它--路径没有在清单中列出。只需在android:pathPrefix="/wearable_data"的data部分中的android:host="*"后面添加intent-filter。您可以阅读更多关于它的这里。

Answer 2

为了在项目中的移动应用程序和穿戴应用程序之间发送和同步数据，它们必须具有相同的包名，如开发人员注意到的这里中所述，

用Android打包磨损1.x应用程序 要在Android中打包磨损1.x应用程序：

1. 确保手表和手机应用模块都有相同的包名。

还有这里

如果您的磨损2.0应用程序有一个附带的手机应用程序，使用相同的包名称为您的磨损应用程序和那个手机应用程序。

将磨损和移动应用程序更改为具有相同的包名：

com.example.myname.datacollector

或

com.example.name.datacollector

如果不确定如何更改现有项目模块的包名这里，则此堆栈溢出问题将对您有所帮助。
