Le app IoT consentono agli utenti di eseguire azioni pertinenti sui dispositivi connessi dall'interno
dell'auto. Alcuni esempi sono il controllo dello stato di alcuni dispositivi,
aprire la porta del garage, accendere interruttori delle luci in casa o attivare la sicurezza domestica.
Dichiara il supporto delle categorie nel tuo file manifest.
La tua app deve dichiarare androidx.car.app.category.IOT
categoria di app auto nell'intent
del suo CarAppService
.
<application>
...
<service
...
android:name=".MyCarAppService"
android:exported="true">
<intent-filter>
<action android:name="androidx.car.app.CarAppService" />
<category android:name="androidx.car.app.category.IOT"/>
</intent-filter>
</service>
...

Norme sulla qualità delle app per auto per le app IoT
, poiché la tua app verrà esaminata in base a queste linee guida.
Per le app IoT, la GridTemplate
è un'ottima scelta per visualizzare un elenco di dispositivi e consentire all'utente di
interagire con essi, come illustrato nell'esempio seguente:
Kotlin
val listBuilder = ItemList.Builder()
listBuilder.addItem(
GridItem.Builder()
.setTitle("Garage door")
.setImage(...)
// Handle user interactions
.setOnClickListener {...}
.build()
)
listBuilder.addItem(
GridItem.Builder()
.setTitle("Garage lights")
// Show a loading indicator until the status of the device is known
// (call invalidate() when the status is known to refresh the screen)
.setLoading(true)
.build()
)
return GridTemplate.Builder()
.setTitle("Devices")
.setHeaderAction(Action.APP_ICON)
.setSingleList(listBuilder.build())
.build()
Java
ItemList.Builder listBuilder = new ItemList.Builder();
listBuilder.addItem(
new GridItem.Builder()
.setTitle("Garage door")
.setImage(...)
// Handle user interactions
.setOnClickListener(() -> {...})
.build()
);
listBuilder.addItem(
new GridItem.Builder()
.setTitle("Garage lights")
// Show a loading indicator until the status of the device is known
// (call invalidate() when the status is known to refresh the screen)
.setLoading(true)
.build()
);
return new GridTemplate.Builder()
.setTitle("Devices")
.setHeaderAction(Action.APP_ICON)
.setSingleList(listBuilder.build())
.build();

Examples include controlling the state of certain devices, such as\nopening a garage door, flipping home light switches, or enabling home security.\n\nDeclare category support in your manifest\n-----------------------------------------\n\nYour app needs to declare the `androidx.car.app.category.IOT`\n[car app category](/training/cars/apps#supported-app-categories) in the intent\nfilter of its [`CarAppService`](/reference/androidx/car/app/CarAppService). \n\n \u003capplication\u003e\n ...\n \u003cservice\n ...\n android:name=\".MyCarAppService\"\n android:exported=\"true\"\u003e\n \u003cintent-filter\u003e\n \u003caction android:name=\"androidx.car.app.CarAppService\" /\u003e\n \u003ccategory android:name=\"androidx.car.app.category.IOT\"/\u003e\n \u003c/intent-filter\u003e\n \u003c/service\u003e\n ...\n \u003capplication\u003e\n\nImplement your app's functionality\n----------------------------------\n\nTo implement your app, refer to\n[Using the Android for Cars App Library](/training/cars/apps) on how Car App\nLibrary apps are built.
