问题

在基于View框架开发的Activity中，尝试用Jetpack Compose展示Snackbar。需求是当应用处于后台时，用户点击DeepLink触发显示该Snackbar，但编译失败，抛出Backend Internal error: Exception during IR lowering错误，堆栈信息显示生成onNewIntent方法代码时出现异常，具体错误栈如下：

根因：java.lang.RuntimeException: Exception while generating code for: FUN name:onNewIntent

解决方案

检查Kotlin与Compose版本兼容性：这类IR代码生成错误大多源于版本不匹配，确保项目中Kotlin版本和Compose Compiler版本严格对应，比如Kotlin 1.8.20对应Compose Compiler 1.4.7，Kotlin 1.9.0对应Compose Compiler 1.5.0。

重构onNewIntent中的Compose调用逻辑：不要在onNewIntent中直接操作Compose状态或调用Snackbar，通过中间状态传递实现：

在Activity中定义MutableState<Boolean>标记是否显示Snackbar；
在onNewIntent中更新该标记；
在Compose的setContent块中监听标记，触发Snackbar显示并在合适时机重置标记。
示例代码：

class MyViewActivity : AppCompatActivity() {
    private val showSnackbar = mutableStateOf(false)

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            MyTheme {
                // 原有View与Compose整合代码
                if (showSnackbar.value) {
                    Snackbar(
                        action = {
                            Button(onClick = { showSnackbar.value = false }) {
                                Text("关闭")
                            }
                        }
                    ) {
                        Text("DeepLink触发的提示")
                    }
                    // 自动隐藏并重置标记
                    LaunchedEffect(Unit) {
                        delay(3000)
                        showSnackbar.value = false
                    }
                }
            }
        }
    }

    override fun onNewIntent(intent: Intent?) {
        super.onNewIntent(intent)
        // 处理DeepLink逻辑后更新标记
        showSnackbar.value = true
    }
}

清理缓存重新编译：通过Android Studio的File -> Invalidate Caches... -> Invalidate and Restart清除构建缓存，再重新编译项目，排除缓存导致的异常。
避免在View生命周期方法中直接调用Compose API：onNewIntent属于View体系生命周期方法，直接调用Compose相关逻辑容易触发编译器IR生成bug，通过状态中转是更安全的实现方式。
