我在 Gradle 托管设备设置中可能遇到什么问题？

Question

引入了一项新功能 Gradle 管理设备（参见此处的示例： https: //developer.android.com/studio/preview/features?hl=fr）

设置似乎非常简单，只需将几行复制到模块级build.gradle文件中，一切就应该可以工作。

可悲的是，我的情况并非如此，我努力寻求一些建议，请。代码为红色，脚本未成功。查看我的build.gradle.kts文件：

带下划线的 ManagedVirtualDevice 显示以下错误：

我的Android studio版本是Android Studio Bumblebee | 2021.1.1 Canary 11 Build #AI-211.7628.21.2111.7676841，建于 2021 年 8 月 26 日。

同步 Gradle 显示了以下内容：

Answer 1

刚刚遇到了同样的问题 - 您需要实例化一个ManagedVirtualDevice对象并配置它，然后再将其添加到设备列表中：

import com.android.build.gradle.internal.dsl.ManagedVirtualDevice

testOptions {
    devices {
        add(
            ManagedVirtualDevice("pixel2api30").apply {
                device = "Pixel 2"
                apiLevel = 30
                systemImageSource = "aosp-atd"
                abi = "x86"
            }
        )
    }
}

请注意，导入与 Google 文档中的内容略有不同 - 在他们的示例中，他们传递的是接口，而不是实现。

正确的等效方法是使用 a 的方法NamedDomainObjectContainer：

import com.android.build.api.dsl.ManagedVirtualDevice
android {
    testOptions {
        devices {
            // create it now (if it doesn't exist yet) and configure it (exactly as in Groovy):
            maybeCreate<ManagedVirtualDevice>("pixel2api29").apply { ... }

            // or

            // create it now and configure it:
            create<ManagedVirtualDevice>("pixel2api29") { ... }

            // or

            // create it later and configure it:
            register<ManagedVirtualDevice>("pixel2api29") { ... }

            // or

            // if it already exists (created elsewhere), configure it:
            "pixel2api29"(ManagedVirtualDevice::class) { ... }

或者by在您需要引用设备（例如组）的情况下使用：

devices {
    val pixel2api29 by creating(ManagedVirtualDevice::class) { ... }
    // or
    val pixel2api29 by registering(ManagedVirtualDevice::class) { ... }
    deviceGroups {
        "phoneAndTablet" {
            targetDevices.add(pixel2api29)
        }
    }
}
