我正在尝试构建一个计步器应用程序，作为测试，我从 github 下载了 android fit 代码并运行了 basicsensorsAPI：

googlesamples/android-fit

为了获得步数而不是位置，我将数据类型更改为TYPE_STEP_COUNT_CUMULATIVE 和 TYPE_DERIVED（原件是TYPE_LOCATION_SAMPLE 和 TYPE_RAW）。但是一旦我这样做，OAUTH 就会停止工作，我不确定为什么这会造成问题。

这是更改后的代码：

private void findFitnessDataSources() {
    // [START find_data_sources]
    // Note: Fitness.SensorsApi.findDataSources() requires the ACCESS_FINE_LOCATION permission.
    Fitness.SensorsApi.findDataSources(mClient, new DataSourcesRequest.Builder()
            // At least one datatype must be specified.
            .setDataTypes(DataType.TYPE_STEP_COUNT_CUMULATIVE)
                    // Can specify whether data type is raw or derived.
            .setDataSourceTypes(DataSource.TYPE_DERIVED)
            .build())
            .setResultCallback(new ResultCallback<DataSourcesResult>() {
                @Override
                public void onResult(DataSourcesResult dataSourcesResult) {
                    Log.i(TAG, "Result: " + dataSourcesResult.getStatus().toString());
                    for (DataSource dataSource : dataSourcesResult.getDataSources()) {
                        Log.i(TAG, "Data source found: " + dataSource.toString());
                        Log.i(TAG, "Data Source type: " + dataSource.getDataType().getName());

                        //Let's register a listener to receive Activity data!
                        if (dataSource.getDataType().equals(DataType.TYPE_STEP_COUNT_CUMULATIVE)
                                && mListener == null) {
                            Log.i(TAG, "Data source for LOCATION_SAMPLE found!  Registering.");
                            registerFitnessDataListener(dataSource,
                                    DataType.TYPE_STEP_COUNT_CUMULATIVE);
                        }
                    }
                }
            });
    // [END find_data_sources]
}

这是原始代码：

private void findFitnessDataSources() {
    // [START find_data_sources]
    // Note: Fitness.SensorsApi.findDataSources() requires the ACCESS_FINE_LOCATION permission.
    Fitness.SensorsApi.findDataSources(mClient, new DataSourcesRequest.Builder()
            // At least one datatype must be specified.
            .setDataTypes(DataType.TYPE_LOCATION_SAMPLE)
            // Can specify whether data type is raw or derived.
            .setDataSourceTypes(DataSource.TYPE_RAW)
            .build())
            .setResultCallback(new ResultCallback<DataSourcesResult>() {
                @Override
                public void onResult(DataSourcesResult dataSourcesResult) {
                    Log.i(TAG, "Result: " + dataSourcesResult.getStatus().toString());
                    for (DataSource dataSource : dataSourcesResult.getDataSources()) {
                        Log.i(TAG, "Data source found: " + dataSource.toString());
                        Log.i(TAG, "Data Source type: " + dataSource.getDataType().getName());

                        //Let's register a listener to receive Activity data!
                        if (dataSource.getDataType().equals(DataType.TYPE_LOCATION_SAMPLE)
                                && mListener == null) {
                            Log.i(TAG, "Data source for LOCATION_SAMPLE found!  Registering.");
                            registerFitnessDataListener(dataSource,
                                    DataType.TYPE_LOCATION_SAMPLE);
                        }
                    }
                }
            });
    // [END find_data_sources]
}

我得到这个输出：应用程序需要用户的 oAuth 同意。

我也遇到过这个问题。
如果您遇到此问题，您需要请求许可：只需将此代码添加到您的onResult()方法中

if (dataSourcesResult.getStatus().getStatusCode()==5000)
{
    try {
        dataSourcesResult.getStatus().startResolutionForResult(SplashActivity.this,10);
    } catch (IntentSender.SendIntentException e) {
        e.printStackTrace();
    }
}

并onActivityResult再次调用您的方法

if (requestCode==10 && resultCode==RESULT_OK)
{
    findFitnessDataSources();
}

它关于范围。访问这个谷歌开发者页面

您为其添加数据的数据类型应在范围内。意味着如果你想添加

  DataType.TYPE_DISTANCE_CUMULATIVE

您需要添加相关范围。这是

 .addScope(new Scope(Scopes.FITNESS_LOCATION_READ_WRITE))

如果你想添加

DataType.TYPE_STEP_COUNT_DELTA

比你需要添加范围

https://www.googleapis.com/auth/fitness.activity.write

或“FITNESS_ACTIVITY_READ_WRITE”

根据此Android 入门指南：

第 3 步：获取 OAuth 2.0 客户端 ID

如果您尚未启用 Fitness API 并获得 OAuth 2.0 客户端 ID，请按照获取 OAuth 2.0 客户端 ID 中的说明立即执行此操作。

还，

安卓授权

在您的应用读取或写入健身数据之前，始终需要用户同意。要获得授权：

  • 在 Google Developers Console 中向项目注册您的 Android 应用。
  • 连接健身服务时指定访问范围。

在 Google Fit 中，范围是确定应用可以访问哪些健身数据以及访问这些数据的级别的字符串。

授权流程如下：

  • 您的应用程序请求与健身服务建立一个或多个访问范围的连接。
  • Google Fit 会提示用户授予您的应用所需的权限。
  • 如果用户同意，您的应用可以访问范围定义的类型的健身数据。

用户请求的特定权限取决于您的应用在连接到服务时指定的范围。

连接到 Google Fit Platform，然后检查并请求您在应用中使用的 Fit API 的权限：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // Put application specific code here.

    setContentView(R.layout.activity_main);
    // This method sets up our custom logger, which will print all log messages to the device
    // screen, as well as to adb logcat.
    initializeLogging();

    // When permissions are revoked the app is restarted so onCreate is sufficient to check for
    // permissions core to the Activity's functionality.
    if (!checkPermissions()) {
        requestPermissions();
    }
}

创建 Google API 客户端并提供所需的回调方法：

**
 *  Build a {@link GoogleApiClient} that will authenticate the user and allow the application
 *  to connect to Fitness APIs. The scopes included should match the scopes your app needs
 *  (see documentation for details). Authentication will occasionally fail intentionally,
 *  and in those cases, there will be a known resolution, which the OnConnectionFailedListener()
 *  can address. Examples of this include the user never having signed in before, or having
 *  multiple accounts on the device and needing to specify which account to use, etc.

private void buildFitnessClient() {
    if (mClient == null && checkPermissions()) {
        mClient = new GoogleApiClient.Builder(this)
