[Android] 如何快速开发一个健康助手，实时守护用户健康

• 注册帐号及申请帐号服务：因Health Kit服务需要用到帐号服务的能力，需先申请华为帐号服务后才能申请Health Kit服务。
• 申请Health Kit服务：申请产品所需的数据读写权限。在开发服务中找到并申请Health Kit服务。勾选产品需要申请的数据权限，这里我们需要申请的身高、体重属于非受限数据，提交申请后会快速审核通过，心率、血压、血糖、血氧饱和度属于受限数据，需要经过人工审核。
  

• 集成HMS Core SDK：在开发应用前，需要将Health Kit扩展服务能力的SDK集成到开发环境中。
  

maven {url 'https://developer.huawei.com/repo/'}

implementation 'com.huawei.hms:health:{version}'

• 配置混淆脚本：编译APK前需要配置混淆配置文件，避免混淆HMS Core SDK导致功能异常。
  

-ignorewarnings
-keepattributes *Annotation*
-keepattributes Exceptions
-keepattributes InnerClasses
-keepattributes Signature
-keepattributes SourceFile,LineNumberTable
-keep class com.huawei.hianalytics.**{*;}
-keep class com.huawei.updatesdk.**{*;}
-keep class com.huawei.hms.**{*;}

• 导入证书指纹、修改包名、配置JDK编译版本：
  根据“创建应用的Keystore文件”指南，生成Keystore文件并导入到应用中，导入后，打开应用级的“build.gradle”文件，可以看到导入的结果。
  

compileOptions {
  sourceCompatibility = '1.8'
  targetCompatibility = '1.8'
}

• 拉起登录页面进行登录授权。
  

/**
 * Add scopes to apply for and obtains the authorization process Intent.
 */
private void requestAuth() {
  // Add scopes to apply for. The following only shows an example.
  // Developers need to add scopes according to their specific needs.
  String[] allScopes = Scopes.getAllScopes();
  // Obtains the authorization process Intent.
  // True indicates that the health app authorization process is enabled. False indicates disabled.
  Intent intent = mSettingController.requestAuthorizationIntent(allScopes, true);

  // The authorization process page is displayed.
  startActivityForResult(intent, REQUEST_AUTH);
}

• 调用 com.huawei.hms.hihealth. DataController类的readLatestData() 接口，读取健康相关的最新数据。包括用户的身高、体重、心率、血压、血糖和血氧。
  

/**
 * read the latest data basing on data type
 *
 * @param view (indicating a UI object)
 */
public void readLatestData(View view) {
  // 1. Use the specified data type (DT_INSTANTANEOUS_HEIGHT) to call the data controller to query
  // the latest data of this data type.
  List<DataType> dataTypes = new ArrayList<>();
  dataTypes.add(DataType.DT_INSTANTANEOUS_HEIGHT);
  dataTypes.add(DataType.DT_INSTANTANEOUS_BODY_WEIGHT);
  dataTypes.add(DataType.DT_INSTANTANEOUS_HEART_RATE);
  dataTypes.add(DataType.DT_INSTANTANEOUS_STRESS);
  dataTypes.add(HealthDataTypes.DT_INSTANTANEOUS_BLOOD_PRESSURE);
  dataTypes.add(HealthDataTypes.DT_INSTANTANEOUS_BLOOD_GLUCOSE);
  dataTypes.add(HealthDataTypes.DT_INSTANTANEOUS_SPO2);
  Task<Map<DataType, SamplePoint>> readLatestDatas = dataController.readLatestData(dataTypes);

  // 2. Calling the data controller to query the latest data is an asynchronous operation.
  // Therefore, a listener needs to be registered to monitor whether the data query is successful or not.
  readLatestDatas.addOnSuccessListener(new OnSuccessListener<Map<DataType, SamplePoint>>() {
    @Override
    public void onSuccess(Map<DataType, SamplePoint> samplePointMap) {
      logger("Success read latest data from HMS core");
      if (samplePointMap != null) {
        for (DataType dataType : dataTypes) {
          if (samplePointMap.containsKey(dataType)) {
            showSamplePoint(samplePointMap.get(dataType));
            handleData(dataType);
          } else {
            logger("The DataType " + dataType.getName() + " has no latest data");
          }
        }
      }
    }
  });
  readLatestDatas.addOnFailureListener(new OnFailureListener() {
    @Override
    public void onFailure(Exception e) {
      String errorCode = e.getMessage();
      String errorMsg = HiHealthStatusCodes.getStatusCodeMessage(Integer.parseInt(errorCode));
      logger(errorCode + ": " + errorMsg);
    }
  });
}
