Question

我正在尝试使用可穿戴邮件API在手机和可穿戴设备之间发送消息。手机（物理一加一）和智能手表（物理索尼智能手表3）将相互连接。发送消息也会报告为已发送。但是Mobile和可穿戴应用程序的WearableServiceListener都不会响应这些消息。

我查了一下：

的applicationID
包名称
清单

我还能检查什么来发现问题？谢谢

public class MainActivityPhone extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {

private Node connectedPhone;
private static String WEAR_PATH = "/from_phone";
private final String TAG = MainActivityPhone.class.getSimpleName();
GoogleApiClient googleApiClient;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    googleApiClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(Wearable.API)
            .build();
    googleApiClient.connect();

}

public void phoneButtonHandler(View view){
    sendMessage();
}

@Override
public void onConnectionSuspended(int i) {

    Log.e(TAG,"connection suspended");
}

@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
    Log.e(TAG,"connection failed");
}
@Override
public void onConnected(Bundle bundle) {

    Wearable.NodeApi.getConnectedNodes(googleApiClient)
            .setResultCallback(new ResultCallbacks<NodeApi.GetConnectedNodesResult>() {
                @Override
                public void onSuccess(@NonNull NodeApi.GetConnectedNodesResult nodes) {
                    for (Node node : nodes.getNodes()) {
                        if (node != null && node.isNearby()) {
                            connectedPhone = node;
                            Log.i(TAG, "Connected to " + connectedPhone.getDisplayName());
                        }
                    }
                }

                @Override
                public void onFailure(@NonNull Status status) {
                    if (connectedPhone == null) {
                        Log.i(TAG, "not connected!");
                    }
                }
            });
}

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

@Override
protected void onStop() {
    super.onStop();
    googleApiClient.disconnect();
}

private void sendMessage(){

    if(connectedPhone != null && googleApiClient != null) {

        Wearable.MessageApi.sendMessage(googleApiClient, connectedPhone.getId(), WEAR_PATH, "alarm".getBytes()).setResultCallback(new ResultCallbacks<MessageApi.SendMessageResult>() {
            @Override
            public void onSuccess(@NonNull MessageApi.SendMessageResult sendMessageResult) {

                Log.e(TAG, "message sent");
            }

            @Override
            public void onFailure(@NonNull Status status) {

                Log.e(TAG, "connection failed!" + status.getStatusMessage());
            }
        });
    }
    else{
        Toast.makeText(this,"failed to send, no connection",Toast.LENGTH_SHORT).show();
    }
}

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

以及两个模块：

android {
compileSdkVersion 24
buildToolsVersion "24.0.2"
defaultConfig {
    applicationId "com.leon_wolf.bigpresenter.connectphoneandwatch"
    minSdkVersion 23
    targetSdkVersion 24
    versionCode 1
    versionName "1.0"

Answer 1

将您的服务定义更改为：

std::vector<int> hash_vec{0,2,3};

    using it = std::vector<int>::iterator;
    IterableHash<it> hasher(hash_vec.begin(),
                     hash_vec.end());

    ApproxEqual<IterableHash<it>> cmp(hasher);
    std::unordered_map<std::vector<char>, int, IterableHash<it>, ApproxEqual<IterableHash<it>> > map( 0, hasher,
                                                                                            cmp);
    std::vector<char> vec {1,0,1,0,1};
    map[vec] = 33;

    std::cout << hasher(vec)<< "\n";


    std::vector<char> fuzzy_vec {1,0,1,0,0};

    std::cout << hasher(fuzzy_vec)<< "\n";
    std::cout << (map.find(fuzzy_vec)->second);

您需要在此处详细说明<service android:name=".ListenerFromWear"> <intent-filter> <action android:name="com.google.android.gms.wearable.MESSAGE_RECEIVED" /> <data android:host="*" android:scheme="wear" /> </intent-filter> </service>方案：

还要确保wear扩展Service

Android 6.1和Smartwatch无法通信WearableListenerService
