Les appareils de fitness qui implémentent une norme Bluetooth à basse consommation
GATT
sont automatiquement pris en charge par Google Fit. Si votre appareil
n'implémente pas l'un de ces profils, vous pouvez créer une application Android qui
gère la communication avec l'appareil de fitness et l'expose à
Google Fit en tant que capteur logiciel. Vous pouvez aussi exposer des logiciels
capteurs dans votre application.
Pour créer un capteur logiciel dans votre application, vous devez étendre la
FitnessSensorService
et la déclarer en tant que service dans le fichier manifeste. Lorsque les utilisateurs installent votre
application, Google Fit met vos capteurs logiciels à la disposition d'autres applications.
Lorsqu'une application s'enregistre pour recevoir des données d'un capteur logiciel dans votre application,
Google Fit est lié à votre service.
Déclarer un service de capteurs
Pour définir un capteur logiciel, déclarez un
FitnessSensorService
dans le fichier manifeste de votre application:
<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>
Dans cet exemple, le service s'exécute dans un processus distinct, comme spécifié par le paramètre
android:process
. Pour en savoir plus, consultez
Processus.
Implémenter un service de capteurs
Pour implémenter un capteur logiciel, étendez la classe FitnessSensorService
et
pour implémenter ses méthodes abstraites. Les détails de l'implémentation dépendent de votre
particulier, mais l'exemple suivant fournit des consignes générales:
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
}

If your device\ndoesn't implement one of these profiles, you can create an Android app that\nmanages the communication with the fitness device and exposes it to\nGoogle Fit as a software sensor. You can also expose custom software\nsensors in your app.\n\nTo create a software sensor in your app, you extend the\n[`FitnessSensorService`](/android/reference/com/google/android/gms/fitness/service/FitnessSensorService)\nclass and declare it as a service in the manifest file. When users install your\napp, Google Fit makes your software sensors available to other apps.\nWhen an app registers to receive data from a software sensor in your app,\nGoogle Fit binds to your service.\n| **Note:** For best practices when you manage user data, see [Google Fit Developer and User Data Policy](/fit/policy).\n\nDeclare a sensor service\n------------------------\n\nTo define a software sensor, declare a\n[`FitnessSensorService`](/android/reference/com/google/android/gms/fitness/service/FitnessSensorService)\nin your app's manifest file: \n\n```carbon\n\u003cservice android:name=\"com.example.MySensorService\"\n android:process=\":sensor\"\u003e\n \u003cintent-filter\u003e\n \u003caction android:name=\"com.google.android.gms.fitness.service.FitnessSensorService\" /\u003e\n \u003c!-- include at least one mimeType filter for the supported data types --\u003e\n \u003cdata android:mimeType=\"vnd.google.fitness.data_type/com.google.heart_rate.bpm\" /\u003e\n \u003c/intent-filter\u003e\n\u003c/service\u003e\n```\n\nThe service in this example runs in a separate process, as specified by the\n[`android:process`](https://developer.android.com/guide/topics/manifest/service-element#proc)\nattribute. For more information, see\n[Processes](https://developer.android.com/guide/components/processes-and-threads#Processes).\n\nImplement a sensor service\n--------------------------\n\nTo implement a software sensor, extend the `FitnessSensorService` class and\nimplement its abstract methods. The details of the implementation depend on your\nparticular use case, but the following example provides general guidelines: \n\n### Kotlin\n\n```kotlin\nclass MySensorService : FitnessSensorService() {\n override fun onCreate() {\n super.onCreate()\n // 1. Initialize your software sensor(s).\n // 2. Create DataSource representations of your software sensor(s).\n // 3. Initialize some data structure to keep track of a registration\n // for each sensor.\n }\n\n override fun onFindDataSources(dataTypes: List\u003cDataType\u003e): List\u003cDataSource\u003e {\n // 1. Find which of your software sensors provide the data types requested.\n // 2. Return those as a list of DataSource objects.\n }\n\n override fun onRegister(request: FitnessSensorServiceRequest): Boolean {\n // 1. Determine which sensor to register with request.dataSource.\n // 2. If a registration for this sensor already exists, replace it with\n // this one.\n // 3. Keep (or update) a reference to the request object.\n // 4. Configure your sensor according to the request parameters.\n // 5. When the sensor has new data, deliver it to the platform by\n // calling request.dispatcher.publish(dataPoints)\n }\n\n override fun onUnregister(dataSource: DataSource): Boolean {\n // 1. Configure this sensor to stop delivering data to the platform\n // 2. Discard the reference to the registration request object\n }\n}\n```\n\n### Java\n\n```java\npublic class MySensorService extends FitnessSensorService {\n @Override\n public void onCreate() {\n super.onCreate();\n // 1. Initialize your software sensor(s).\n // 2. Create DataSource representations of your software sensor(s).\n // 3. Initialize some data structure to keep track of a registration\n // for each sensor.\n }\n\n @NonNull\n @Override\n public List\u003cDataSource\u003e onFindDataSources(@NonNull List\u003cDataType\u003e list) {\n // 1. Find which of your software sensors provide the data types\n // requested.\n // 2. Return those as a list of DataSource objects.\n }\n\n @Override\n public boolean onRegister(\n @NonNull FitnessSensorServiceRequest fitnessSensorServiceRequest) {\n // 1. Determine which sensor to register with request.dataSource.\n // 2. If a registration for this sensor already exists, replace it with\n // this one.\n // 3. Keep (or update) a reference to the request object.\n // 4. Configure your sensor according to the request parameters.\n // 5. When the sensor has new data, deliver it to the platform by\n // calling request.getDispatcher.publish(dataPoints);\n }\n\n @Override\n public boolean onUnregister(@NonNull DataSource dataSource) {\n // 1.
