android - 与 Jetpack Compose 一起使用时，WebView 在输入时崩溃

Question

当创建一个简单的 WebView使用 Jetpack Compose 进行包装，当我输入任何文本时，应用程序就会崩溃。这是一个错误，还是我在做一些愚蠢的事情？相关代码:

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            WebViewC()
        }
    }
}

@Composable
fun WebViewC() {
    return AndroidView(viewBlock = { context ->
        WebView(context).apply {
            layoutParams = ViewGroup.LayoutParams(
                ViewGroup.LayoutParams.MATCH_PARENT,
                ViewGroup.LayoutParams.MATCH_PARENT
            )
            webViewClient = object : WebViewClient() {
                override fun shouldOverrideUrlLoading(view: WebView?, url: String?): Boolean {
                    return false
                }
            }
            loadUrl("https://google.com")
        }
    })
}

如果要动态更改 url，还需要添加更新方法。

@SuppressLint("SetJavaScriptEnabled")
@Composable
fun WebPageScreen(urlToRender: String) {
  AndroidView(factory = {
    WebView(it).apply {
      layoutParams = ViewGroup.LayoutParams(
          ViewGroup.LayoutParams.MATCH_PARENT,
          ViewGroup.LayoutParams.MATCH_PARENT
      )
      webViewClient = WebViewClient()
      loadUrl(urlToRender)
    }
  }, update = {
    it.loadUrl(urlToRender)
  })
}
