我正在使用 Jetpack Compose 开发一个 Android 应用程序，当我想使用 DrawImage () 添加新图像时，kotlin 语言的编译给了我一个错误，我正在从 android 开发人员页面获取官方 Jetpack Compose 示例中的代码到添加图像。我花了几个小时寻找这个问题的答案，但我什么也没找到。有人可以帮我解决这个错误吗？
如果我启用
composeOptions{
kotlinCompilerVersion "1.3.61-dev-withExperimentalGoogleExtensions-20200129"
kotlinCompilerExtensionVersion "0.1.0-dev04"
}
在我的应用程序级别 build.gradle 文件上，编译完成时没有错误，但是当我运行应用程序时，图像不会出现，然后应用程序崩溃。
这是我的 MainActivity.kt 文件:
package com.firecodes.surveyflow
import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import androidx.compose.Composable
import androidx.compose.ambient
import androidx.ui.core.ContextAmbient
import androidx.ui.core.Text
import androidx.ui.core.setContent
import androidx.ui.foundation.DrawImage
import androidx.ui.foundation.SimpleImage
import androidx.ui.graphics.imageFromResource
import androidx.ui.layout.Center
import androidx.ui.material.MaterialTheme
import androidx.ui.material.Scaffold
import androidx.ui.material.TopAppBar
import androidx.ui.res.imageResource
import androidx.ui.tooling.preview.Preview
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
MaterialTheme {
Greeting("Android")
}
}
}
}
@Composable
fun Greeting(name: String) {
val context = ambient(ContextAmbient)
Scaffold(
topAppBar = {
TopAppBar(title = {
Text(text = "Hello $name")
})
},
bodyContent = {
Center {
DrawImage(image = imageResource(id = R.drawable.surveyflow))
}
}
)
}
@Preview
@Composable
fun DefaultPreview() {
MaterialTheme {
Greeting("Android")
}
}
这是错误:

这是我的毕业典礼:
