Google Fit API:存储心率bmp数据点

我正在尝试在我的应用中实现Google Fit,但是在存储心率bpm数据点的权限方面遇到麻烦。起初,我仅尝试插入活动,速度,距离和步速数据,并且该方法有效。但是,一旦我添加了心率bpm许可和数据点,我就会从api中收到错误5000。

这些是我要求的健身权限:

FitnessOptions.builder()
.addDataType(DataType.TYPE_ACTIVITY_SEGMENT, FitnessOptions.ACCESS_WRITE)
.addDataType(DataType.TYPE_SPEED, FitnessOptions.ACCESS_WRITE)
.addDataType(DataType.TYPE_DISTANCE_CUMULATIVE, FitnessOptions.ACCESS_WRITE)
.addDataType(DataType.TYPE_STEP_COUNT_CUMULATIVE, FitnessOptions.ACCESS_WRITE)
.addDataType(DataType.TYPE_HEART_RATE_BPM, FitnessOptions.ACCESS_WRITE)
.build();

然后,当我尝试使用会话api存储数据类型为TYPE_HEART_RATE_BPM的数据集时,出现错误5000。

我也尝试在Google Fit应用程序中完全删除我的应用程序的权限,然后再次添加该权限,但是我仍然收到错误消息。可能需要额外的许可来存储心率数据吗?还是只允许读取心率数据?

我以前曾尝试使用Google Fit获取心率数据。最初,我遇到了同样的问题。如果您浏览以下链接中的文档 https://developers.google.com/android/reference/com/google/android/gms/fitness/data/DataType.html#TYPE_HEART_RATE_BPM

明确提到您需要获得BODY_SENSORS权限

"Registering to, or subscribing to data of this type requires BODY_SENSORS"

如果用户未授予BODY_SENSORS的权限,那么我们将收到错误消息,因为我们将无法访问或插入心率数据。

您可以使用以下代码来请求用户授予权限

ActivityCompat.requestPermissions(context, new String[]{Manifest.permission.BODY_SENSORS},
                            BODY_SENSOR_PERMISSION_REQUEST_CODE);

您可以在“ onRequestPermissionsResult”回调中检查用户是否已授予权限,然后请求获取心率数据。

根据要求添加示例代码。

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                requestPermissions(new String[]{android.Manifest.permission.BODY_SENSORS},
                        BODY_SENSOR_PERMISSION_REQUEST_CODE);
            }



private class InsertAndVerifyDataTask extends AsyncTask<Void, Void, Void> {
        protected Void doInBackground(Void... params) {
            // Create a new dataset and insertion request.
            DataSet dataSet = insertHeartData();
            // [START insert_dataset]
            // Then, invoke the History API to insert the data and await the result, which is
            // possible here because of the {@link AsyncTask}. Always include a timeout when calling
            // await() to prevent hanging that can occur from the service being shutdown because
            // of low memory or other conditions.
            com.google.android.gms.common.api.Status insertStatus =
                    Fitness.HistoryApi.insertData(connectFit.returnClient(), dataSet)
                            .await(1, TimeUnit.MINUTES);
            // Before querying the data, check to see if the insertion succeeded.
            if (!insertStatus.isSuccess()) {
                return null;
            }
            return null;
        }

        @Override
        protected void onPostExecute(Void aVoid) {
            super.onPostExecute(aVoid);
            Toast.makeText(MainActivity.this, "Added", Toast.LENGTH_SHORT).show();
        }
    }

private DataSet insertHeartData() {
        // [START build_insert_data_request]

        try {
            Calendar cal = Calendar.getInstance();
            Date now = new Date();
            cal.setTime(now);
            long endTime = cal.getTimeInMillis();
            cal.add(Calendar.HOUR_OF_DAY, -1);
            long startTime = cal.getTimeInMillis();
            // Create a data source
            DataSource dataSource = new DataSource.Builder()
                    .setAppPackageName(this)
                    .setDataType(DataType.TYPE_HEART_RATE_BPM)
                    .setStreamName(" - heart count")
                    .setType(DataSource.TYPE_DERIVED)
                    .build();
            // Create a data set
            float hearRate = Float.parseFloat(((EditText) (findViewById(R.id.heartRate))).getText().toString().trim());
            DataSet dataSet = DataSet.create(dataSource);
            // For each data point, specify a start time, end time, and the data value -- in this case,
            // the number of new steps.
            DataPoint dataPoint = dataSet.createDataPoint()
                    .setTimeInterval(startTime, endTime, MILLISECONDS);
            dataPoint.getValue(Field.FIELD_BPM).setFloat(hearRate);
            dataSet.add(dataPoint);
            // [END build_insert_data_request]
            return dataSet;
        } catch (Exception e) {
            return null;
        }
    }

这对我有用。
