android - ktor android本地http服务器抛出错误

Question

我做了什么？

在 build.gradle 下添加了依赖项

implementation "io.ktor:ktor:1.3.2"
implementation "io.ktor:ktor-server-netty:1.3.2"
implementation "io.ktor:ktor-gson:1.3.2"

AndroidMenifest.xml

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.BLUETOOTH" />

MainActivity.kt

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        embeddedServer(Netty, 9000) {
            install(ContentNegotiation) {
                gson {}
            }
            routing {
                get("/") {
                    call.respond(mapOf("message" to "Hello world"))
                }
            }
        }.start(wait = true)
    }
}

什么地方出了错？
运行应用程序时，出现以下错误并且 android 本地服务器未启动。

No implementation found for int io.netty.channel.kqueue.Native.sizeofKEvent() 
(tried Java_io_netty_channel_kqueue_Native_sizeofKEvent 
and Java_io_netty_channel_kqueue_Native_sizeofKEvent__)

No implementation found for int io.netty.channel.epoll.Native.offsetofEpollData() 
(tried Java_io_netty_channel_epoll_Native_offsetofEpollData 
and Java_io_netty_channel_epoll_Native_offsetofEpollData__)

我是如何解决的？

在 build.gradle 下添加了依赖项

implementation "io.ktor:ktor:1.3.2"
implementation "io.ktor:ktor-server-jetty:1.3.2"
implementation "io.ktor:ktor-gson:1.3.2"

还

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}
defaultConfig {
    ...
    minSdkVersion 26
    ...
}

AndroidMenifest.xml

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.BLUETOOTH" />

MainActivity.kt

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        embeddedServer(Jetty, 9000) {
            install(ContentNegotiation) {
                gson {}
            }
            routing {
                get("/") {
                    call.respond(mapOf("message" to "Hello world"))
                }
            }
