使用 Google fit 从配对应用程序中读取 Wear os 手表的心率

Question

我正在尝试使用 Google fit api 从我的 Android wear-os 手表获取心率。 我的手表和安卓设备都已配对。

我尝试了两种方法：

1) 从 Android 应用程序连接到 google fit 并扫描数据源。但它只会检测我的安卓设备上的步数传感器，而不会检测到配对的手表传感器。

mFitnessClient = new GoogleApiClient.Builder(this)
 .addApi(Fitness.SENSORS_API)
 .addScope(Fitness.SCOPE_BODY_READ)
 .addConnectionCallbacks(new GoogleApiClient.ConnectionCallbacks() {
  @Override
  public void onConnected(Bundle bundle) {
   Log.d(TAG, "Fitness client connected");
  }

  @Override
  public void onConnectionSuspended(int i) {
   Log.d(TAG, "Fitness client suspended");
  }
 })
 .addOnConnectionFailedListener(new GoogleApiClient.OnConnectionFailedListener() {
  @Override
  public void onConnectionFailed(ConnectionResult result) {
   Log.d(TAG, "Fitness Connection failed");
  }
 })
 .build();
mFitnessClient.connect();

DataSourcesRequest dataSourceRequest = new DataSourcesRequest.Builder()
 .setDataTypes(DataType.TYPE_HEART_RATE_BPM)
 .setDataSourceTypes(DataSource.TYPE_RAW)
 .build();

ResultCallback < DataSourcesResult > dataSourcesResultCallback = new ResultCallback < DataSourcesResult > () {
 @Override
 public void onResult(DataSourcesResult dataSourcesResult) {
  for (DataSource dataSource: dataSourcesResult.getDataSources()) {

  }
 }
};

Fitness.SensorsApi.findDataSources(mFitnessClient, dataSourceRequest)
 .setResultCallback(dataSourcesResultCallback);

2) 直接从手表中读取作为磨损操作系统应用程序。但如果我定义 Fitness.SENSORS_API，我往往会得到 onConnectionFailed，错误代码为 5 (INVALID_ACCOUNT)。

mFitnessClient = new GoogleApiClient.Builder(this)
 .addApi(Fitness.SENSORS_API)
 .addScope(Fitness.SCOPE_BODY_READ)
 .addConnectionCallbacks(new GoogleApiClient.ConnectionCallbacks() {
  @Override
  public void onConnected(Bundle bundle) {
   Log.d(LOG_TAG, "Connected to fitness API");

  }

  @Override
  public void onConnectionSuspended(int i) {

  }
 })
 .addOnConnectionFailedListener(new GoogleApiClient.OnConnectionFailedListener() {
  @Override
  public void onConnectionFailed(ConnectionResult connectionResult) {
   Log.d(LOG_TAG, "Connection failed: " + connectionResult.getErrorCode());
  }
 })
 .build();
mFitnessClient.connect();

1) 从 Android 应用程序连接到 google fit 并扫描数据源。但它只会检测我的安卓设备上的步数传感器，而不会检测到配对的手表传感器。

您可以使用 RecordingClient

获取心率

Android 10 为需要检测用户步数或对用户身体活动进行分类的应用引入了 android.permission.ACTIVITY_RECOGNITION 运行时权限。

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.Q) {
            if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACTIVITY_RECOGNITION)
                    != PackageManager.PERMISSION_GRANTED) {

                ActivityCompat.requestPermissions(this,
                        PERMISSIONS,
                        PERMISSIONS_REQUEST_ACTIVITY_RECOGNITION);
            }
        } else {
            fintessConnection();

        }


public void fintessConnection() {
        FitnessOptions fitnessOptions = FitnessOptions.builder()
                .addDataType(DataType.TYPE_HEART_RATE_BPM, FitnessOptions.ACCESS_READ)
                .build();
        if (!GoogleSignIn.hasPermissions(GoogleSignIn.getLastSignedInAccount(this), fitnessOptions)) {
            GoogleSignIn.requestPermissions(
                    this, // your activity
                    GOOGLE_FIT_PERMISSIONS_REQUEST_CODE,
                    GoogleSignIn.getLastSignedInAccount(this),
                    fitnessOptions);
        } else {
            accessGoogleFit();
        }
    }

订阅心率/BPM：

Fitness.getRecordingClient(this, GoogleSignIn.getLastSignedInAccount(this))
                .subscribe(DataType.TYPE_HEART_RATE_BPM)
                .addOnSuccessListener(new OnSuccessListener<Void>() {
                    @Override
                    public void onSuccess(Void aVoid) {
                        Log.i(TAG, "Successfully subscribed!");
                    }
                })
                .addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {
                        Log.i(TAG, "There was a problem subscribing.");
                    }
                });

检索 BPM：

 DataReadRequest readRequest = new DataReadRequest.Builder()
                .read(DataType.TYPE_HEART_RATE_BPM)
                .setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
                .bucketByTime(365, TimeUnit.DAYS)
                .build();


        Fitness.getHistoryClient(this, GoogleSignIn.getLastSignedInAccount(this))
                .readData(readRequest)
                .addOnSuccessListener(new OnSuccessListener<DataReadResponse>() {
                    @Override
                    public void onSuccess(DataReadResponse dataReadResponse) {
                        Log.d(TAG, "onSuccess()");

                        for (Bucket bucket : dataReadResponse.getBuckets()) {
                            Log.e("History", "Data returned for Data type: " + bucket.getDataSets());

                            List<DataSet> dataSets = bucket.getDataSets();
                            for (DataSet dataSet : dataSets) {
                                showDataSet(dataSet);
                            }
                        }
                    }
                })
                .addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {
                        Log.e(TAG, "onFailure()", e);
                    }
                })
                .addOnCompleteListener(new OnCompleteListener<DataReadResponse>() {
                    @Override
                    public void onComplete(@NonNull Task<DataReadResponse> task) {
                        Log.d(TAG, "onComplete()");
                    }
                }); 

2) 直接从手表中读取作为磨损操作系统应用程序。但是如果我定义 Fitness.SENSORS_API，我往往会得到 onConnectionFailed，错误代码为 5 (INVALID_ACCOUNT)。

在您可以从 Google Fit API 调用方法之前，您必须连接到以下一个或多个 API 客户端，它们是 Google Play 服务的一部分：

1. 传感器客户端
2. 录音客户端
3. 历史客户端
4. 会话客户端
5. 目标客户
6. BLE 客户端
7. 配置客户端

首先从手持设备连接到上述API，然后您可以在Watch.Detailed Answer here.调用API。
