响应导航/本机堆栈在Android上不起作用
我得到以下错误：
E/unknown:ReactNative: Exception in native call
java.lang.IllegalStateException: In order to use RNScreens components your app's activity need to extend ReactActivity

at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:3654)当我从我的RN包中移除react导航/本机堆栈时，一切都很好。此外，我还收到以下错误(这与此相关吗？)：E/ThemeUtils: View class com.facebook.react.views.text.ReactTextView is and AppCompat widget that can only be used with a Theme.AppCompat theme (or descendant)

react本机屏幕是一个反应导航依赖关系，所以您需要使用它，以使导航工作。使用ReactActivity扩展您的活动，并在本地Android代码中创建或编辑应用程序类：
class YourApplication : Application(), ReactApplication, LifecycleObserver {...}这里的链接https://reactnative.dev/docs/integration-with-existing-apps是有用的，如果你想集成反应-本机已经存在的应用程序，而不想实现ReactApplication和ReactActivity。

你是用旧版的“反应本地人”吗？检查您的android/app/src/main/java/com/(your app)/MainActivity.java文件&更改第一个类行以扩展ReactActivity，如果还没有-
public class MainActivity extends ReactActivity {
...这应该满足您所得到的错误- ReactActivity也是扩展compat类，所以它可能也会修复您的另一个问题
