从撰写更新alpha-11到alpha-12（或beta-01）后，每当我打开具有撰写视图的活动或片段时，我都会遇到此崩溃。

我正在使用AppCompatActivitywhich implements LifecycleOwner，所以这非常奇怪。

我的代码看起来很简单：

    class MyActivity : …

您可以在Github上找到一个示例项目来重现该问题

我一直在尝试使用 Jetpack Compose 作为键盘 UI。最终，当我尝试通过 InputMethodService 膨胀键盘时

class IMEService : InputMethodService() {

    override fun onCreateInputView(): View = KeyboardView(this)
}

通过使用这个视图

class KeyboardView(context: Context) : FrameLayout(context)  {

    init {
        val view = ComposeView(context).apply {
            setContent {
                Keyboard() //<- This is the actual compose UI function
            }
        }
        addView(view)
    }

}

或者

class KeyboardView2 constructor(
    context: Context,

    ) : AbstractComposeView(context) {

  
    @Composable
    override fun Content() {
        Keyboard()
    }
}

但是，当我尝试使用键盘时，出现以下错误

class KeyboardView2 constructor(
    context: Context,

    ) : AbstractComposeView(context) {

  
    @Composable …

这与这个问题相关

如此处所述，我能够使用 Jetpack Compose 创建键盘。现在，在我将项目从 升级alpha-11到alpha-12代码损坏（并且仍然损坏beta-01）之后，每当我尝试打开键盘时，都会收到以下错误：
