android - 适用于 Android 的 Google Fit API

Question

Google Fit 和 flutter
我正在关注 Google 的这份文档:
Google Fit
我不明白第 5 步。我不是 Android 开发人员，也不知道在哪里可以找到代码。 Step 5
例如，它说: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:

传感器客户端

录音客户端

历史客户

session 客户端

目标客户

BLE客户端

配置客户端

现在，我尝试连接第一个 SensorsClient
但是我不知道在哪里找到代码，哪个文件？我是一名 Flutter 开发人员，在第 5 步中需要帮助。
build.grandle

dependencies {
    implementation 'com.google.android.gms:play-services-fitness:18.0.0'
    implementation 'com.google.android.gms:play-services-auth:17.0.0'
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
}

Answer 1

使用谷歌健身 Rest Api在 flutter 。

谷歌通过数据源管理数据。查看所有数据源:

https://www.googleapis.com/fitness/v1/users/me/dataSources

要获得步数:
https://www.googleapis.com/fitness/v1/users/me/dataset:aggregate
请求正文:

{    
    "aggregateBy" : [{    
        "dataSourceId": "derived:com.google.step_count.delta:com.google.android.gms:estimated_steps"    
    }],    
    "bucketByTime": { "durationMillis": 86400000 }, // This is 24 hours    
    "startTimeMillis": 1546210381932,   // Start time    
    "endTimeMillis": 1547210381932  // End Time    
} 

您可以使用fitKit这是用于读取健康和健身数据的 Flutter 插件。在 iOS 上封装 HealthKit，在 Android 上封装 GoogleFit。

    import 'package:fit_kit/fit_kit.dart';

void read() async {
  final results = await FitKit.read(
    DataType.HEART_RATE,
    dateFrom: DateTime.now().subtract(Duration(days: 5)),
    dateTo: DateTime.now(),
  );
}

void readLast() async {
  final result = await FitKit.readLast(DataType.HEIGHT);
}

void readAll() async {
  if (await FitKit.requestPermissions(DataType.values)) {
    for (DataType type in DataType.values) {
      final results = await FitKit.read(
        type,
        dateFrom: DateTime.now().subtract(Duration(days: 5)),
        dateTo: DateTime.now(),
      );
    }
  }
}

如果您正在编写自定义平台特定代码

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:

传感器客户端:客户端在本地和连接的设备中公开不同来源的健身数据，并将实时事件传递给
听众。

录音客户端:客户端，可将传感器数据以低功耗、始终在线的方式在后台收集到 Google Fit 商店。

历史客户:用于在 Google Fit 中插入、删除和读取数据的客户端。

session 客户:用于在 Google Fit 中创建和管理用户 Activity session 的客户端。

目标客户:用于读取用户在 Google Fit 中创建的健身目标的客户端。 BLE客户端

配置客户端:用于访问 Google Fit 中的自定义数据类型和设置的客户端。

您必须连接以上之一。

    DataReadRequest readRequest = new DataReadRequest.Builder()
                .aggregate(DataType.TYPE_STEP_COUNT_DELTA, DataType.AGGREGATE_STEP_COUNT_DELTA)
                .setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
                .bucketByTime(1, TimeUnit.DAYS)
                .enableServerQueries()
                .build();
// History Client 
        Fitness.getHistoryClient(this, GoogleSignIn.getLastSignedInAccount(this))
                .readData(readRequest)
                .addOnSuccessListener(new OnSuccessListener<DataReadResponse>() {
                    @Override
                    public void onSuccess(DataReadResponse dataReadResponse) {
                        Log.d(TAG, "onSuccess()");
                    }
                })
                .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()");
                    }
                });
