支援其他感應器

採用標準 藍牙低功耗 GATT 設定檔的健身裝置，會自動受到 Google Fit 支援。如果您的裝置 「未」實作其中一個設定檔，您可以建立一個 Android 應用程式， 管理與健身裝置的通訊， Google Fit 是軟體感應器。您也可以 感應器。

如要在應用程式中建立軟體感應器，請擴充 FitnessSensorService 類別，並在資訊清單檔案中宣告該類別為服務。使用者安裝應用程式後，Google Fit 會將您的軟體感應器提供給其他應用程式。如果應用程式註冊接收來自應用程式中軟體感應器的資料， Google Fit 會繫結至你的服務。

注意：如要瞭解管理使用者資料時的最佳做法，請參閱 Google Fit 開發人員和使用者資料政策。

宣告感應器服務

如要定義軟體感應器，請宣告 FitnessSensorService敬上 執行以下動作：

<service android:name="com.example.MySensorService"
         android:process=":sensor">
  <intent-filter>
    <action android:name="com.google.android.gms.fitness.service.FitnessSensorService" />
    <!-- include at least one mimeType filter for the supported data types -->
    <data android:mimeType="vnd.google.fitness.data_type/com.google.heart_rate.bpm" />
  </intent-filter>
</service>

本範例中的服務會在 android:process 屬性指定的獨立程序中執行。若需更多資訊，請參閲 程序。

實作感應器服務

如要實作軟體感應器，請擴充 FitnessSensorService 類別和 實作抽象方法實作方式的細節取決於您的特定用途，但以下範例提供一般指引：

Kotlin

class MySensorService : FitnessSensorService() {
    override fun onCreate() {
        super.onCreate()
        // 1. Initialize your software sensor(s).
        // 2. Create DataSource representations of your software sensor(s).
        // 3. Initialize some data structure to keep track of a registration
        // for each sensor.
    }

    override fun onFindDataSources(dataTypes: List<DataType>): List<DataSource> {
        // 1. Find which of your software sensors provide the data types requested.
        // 2. Return those as a list of DataSource objects.
    }

    override fun onRegister(request: FitnessSensorServiceRequest): Boolean {
        // 1. Determine which sensor to register with request.dataSource.
        // 2. If a registration for this sensor already exists, replace it with
        //    this one.
        // 3. Keep (or update) a reference to the request object.
        // 4. Configure your sensor according to the request parameters.
        // 5. When the sensor has new data, deliver it to the platform by
        //    calling request.dispatcher.publish(dataPoints)
    }

    override fun onUnregister(dataSource: DataSource): Boolean {
        // 1. Configure this sensor to stop delivering data to the platform
        // 2. Discard the reference to the registration request object
    }
}

Java

public class MySensorService extends FitnessSensorService {
    @Override
    public void onCreate() {
        super.onCreate();
        // 1. Initialize your software sensor(s).
        // 2. Create DataSource representations of your software sensor(s).
        // 3. Initialize some data structure to keep track of a registration
        //    for each sensor.
    }

    @NonNull
    @Override
    public List<DataSource> onFindDataSources(@NonNull List<DataType> list) {
        // 1. Find which of your software sensors provide the data types
        //    requested.
        // 2. Return those as a list of DataSource objects.
    }

    @Override
    public boolean onRegister(
            @NonNull FitnessSensorServiceRequest fitnessSensorServiceRequest) {
        // 1. Determine which sensor to register with request.dataSource.
        // 2. If a registration for this sensor already exists, replace it with
        //    this one.
        // 3. Keep (or update) a reference to the request object.
        // 4. Configure your sensor according to the request parameters.
        // 5. When the sensor has new data, deliver it to the platform by
        //    calling request.getDispatcher.publish(dataPoints);
    }

    @Override
    public boolean onUnregister(@NonNull DataSource dataSource) {
        // 1. Configure this sensor to stop delivering data to the platform
        // 2. Discard the reference to the registration request object
    }
