初始化驱动程序 SDK
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
在使用 Driver SDK 之前，您必须先按照以下步骤初始化 Navigation SDK 和 Driver SDK：
从 NavigationApi 获取 Navigator 对象。
Java
NavigationApi.getNavigator(
this, // Activity
new NavigationApi.NavigatorListener() {
@Override
public void onNavigatorReady(Navigator navigator) {
// Keep a reference to the Navigator (used to configure and start nav)
this.navigator = navigator;
}
}
);
Kotlin
NavigationApi.getNavigator(
this, // Activity
object : NavigatorListener() {
override fun onNavigatorReady(navigator: Navigator) {
// Keep a reference to the Navigator (used to configure and start nav)
this@myActivity.navigator = navigator
}
},
)
创建一个 DriverContext 对象，并填充必需的字段。如需初始化 DriverContext 对象，您必须输入 Google Cloud 项目的项目 ID 作为 providerId。如需了解如何设置 Google Cloud 项目，请参阅创建 Fleet Engine 项目。
Java
DriverContext driverContext = DriverContext.builder(application)
.setProviderId(providerId)
.setVehicleId(vehicleId)
.setAuthTokenFactory(authTokenFactory)
.setNavigator(navigator)
.setRoadSnappedLocationProvider(
NavigationApi.getRoadSnappedLocationProvider(application))
.build();
Kotlin
val driverContext =
DriverContext.builder(application)
.setProviderId(providerId)
.setVehicleId(vehicleId)
.setAuthTokenFactory(authTokenFactory)
.setNavigator(navigator)
.setRoadSnappedLocationProvider(NavigationApi.getRoadSnappedLocationProvider(application))
.build()
使用 DriverContext 对象初始化 *DriverApi。
DeliveryDriverApi driverApi = DeliveryDriverApi.createInstance(driverContext);
从 API 对象获取 DeliveryVehicleReporter。
（DeliveryVehicleReporter 扩展了 NavigationVehicleReporter。）
DeliveryVehicleReporter vehicleReporter = driverApi.getDeliveryVehicleReporter();
SSL/TLS 相关注意事项
在内部，Driver SDK 实现使用 SSL/TLS 与 Fleet Engine 服务安全地通信。Android API 版本 23 或更低版本可能需要 SecurityProvider 补丁才能与服务器通信。如需详细了解如何在 Android 中使用 SSL，请参阅 Security GMS 提供程序。
本文还包含用于修补安全提供程序的代码示例。

Android API\nversions 23 or\nearlier may require a `SecurityProvider` patch to communicate with the\nserver. For more information about working with SSL in Android, see\n[Security GMS Provider](https://developer.android.com/training/articles/security-gms-provider).\nThe article also contains code samples for patching the security provider.\n\nWhat's next\n-----------\n\n[Get the vehicle ready](/maps/documentation/mobility/driver-sdk/scheduled/android/vehicle-ready)"]]
