Google Fit API for Android

问题

以下是您要翻译的内容：

Google Fit 和 Flutter

我正在按照 Google 的这份文档操作：
Google Fit

我不明白第 5 步。我不是 Android 开发者，不知道在哪里找到代码。第 5 步

例如，文档中写道： 在调用 Google Fit API 的方法之前，您必须连接到以下一个或多个 API 客户端，这些客户端是 Google Play 服务的一部分：

传感器客户端 (Sensors Client)
记录客户端 (Recording Client)
历史客户端 (History Client)
会话客户端 (Sessions Client)
目标客户端 (Goals Client)
BLE 客户端 (BLE Client)
配置客户端 (Config Client)

现在，我尝试连接第一个传感器客户端 (SensorsClient)

但我不知道在哪里找到这段代码，是哪个文件？我是 Flutter 开发者，需要在第 5 步中获得帮助。

build.gradle

dependencies {
    implementation &#39;com.google.android.gms:play-services-fitness:18.0.0&#39;
    implementation &#39;com.google.android.gms:play-services-auth:17.0.0&#39;
    implementation &quot;org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version&quot;
    testImplementation &#39;junit:junit:4.12&#39;
    androidTestImplementation &#39;androidx.test:runner:1.1.1&#39;
    androidTestImplementation &#39;androidx.test.espresso:espresso-core:3.1.1&#39;
}

英文:

Google Fit and Flutter

I am following this documentation from Google:
Google Fit

I don't understand step 5. I am not an Android developer and I have no idea where to locate the code. Step 5

For example, it says: Before you can invoke methods from the Google Fit APIs, you must connect to one or more of the following API clients, which are part of Google Play services:

Sensors Client
Recording Client
History Client
Sessions Client
Goals Client
BLE Client
Config Client

Now, I try to connect the first one SensorsClient

But I don't know where to locate the code, which file? I am a flutter developer and I need help in step 5.

build.grandle

dependencies {
    implementation &#39;com.google.android.gms:play-services-fitness:18.0.0&#39;
    implementation &#39;com.google.android.gms:play-services-auth:17.0.0&#39;
    implementation &quot;org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version&quot;
    testImplementation &#39;junit:junit:4.12&#39;
    androidTestImplementation &#39;androidx.test:runner:1.1.1&#39;
    androidTestImplementation &#39;androidx.test.espresso:espresso-core:3.1.1&#39;

Use Google Fit [Rest Api][1] in Flutter.

使用Google Fit [Rest API][1]在Flutter中。

Google manages the data through data sources. To see all the data sources:

Google通过数据源管理数据。要查看所有的数据源：

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

要获取步数：

https://www.googleapis.com/fitness/v1/users/me/dataset:aggregate
请求体：

{    
    "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    
}

你可以使用[fitKit][2]，这是一个用于读取健康和健身数据的Flutter插件。在iOS上封装了HealthKit，在Android上封装了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(),
      );
    }
  }
}

如果你正在编写自定义的平台特定代码

在调用Google Fit API的方法之前，你必须连接到以下一个或多个API客户端，这些客户端是Google Play服务的一部分：

传感器客户端： 用于在本地和连接设备中公开不同的健身数据源，并将实时事件传递给监听器。
录制客户端： 用于将传感器数据低功耗、始终开启的后台收集到Google Fit存储中。
历史客户端： 用于在Google Fit中插入、删除和读取数据。
会话客户端： 用于在Google Fit中创建和管理用户活动会话。
目标客户端： 用于读取用户在Google Fit中创建的健身目标。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。

你必须连接其中一个。

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();
// 历史客户端
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()");
            }
        });

***If you are writing custom platform-specific code***
Before you can invoke methods from the Google Fit APIs, you must connect to one or more of the following API clients, which are part of Google Play services:
1. ***Sensors Client :*** Client which exposes different sources of fitness data in local and connected devices, and delivers live events to
listeners.
2. ***Recording Client :*** Client which enables low-power, always-on background collection of sensor data into the Google Fit store.
3. ***History Client :*** Client for inserting, deleting, and reading data in Google Fit.
4. ***Sessions Client :*** Client for creating and managing sessions of user activity in Google Fit.
5. ***Goals Client :*** Client for reading fitness Goals created by users in Google Fit. BLE Client
6. ***Config Client :*** Client for accessing custom data types and settings in Google Fit.
You must connect one of above. 
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&lt;DataReadResponse&gt;() {
@Override
public void onSuccess(DataReadResponse dataReadResponse) {
Log.d(TAG, &quot;onSuccess()&quot;);
