React Native Expo SDK 41 Bare wf (Eje​​cted)：在 MainActivity.java 中构建错误 - Android 构建

Question

上下文： 反应原生 世博会 SDK41 裸工作流（已弹出） 安卓构建

在弹出并开始构建时间（EAS Build）之后，我得到了剩下的两个错误： 那些是阻塞的，非常烦人。 我试过了 ： - 定义函数 getMainComponentName 以返回我的主要组件名称字符串 -删除一个和两个覆盖 - 删除 getMainComponentName 并放置我的主要组件名称字符串

我卡住了

/build/workingdir/build/android/app/src/main/java/com/satyamdorville/discover/MainActivity.java:34: error: method does not override or implement a method from a supertype

还有：

/build/workingdir/build/android/app/src/main/java/com/satyamdorville/discover/MainActivity.java:36: error: cannot find symbol   
...
  symbol:   method getMainComponentName())

这是我的 mainActivity.java ：

package com.satyamdorville.discover;
import android.content.res.Configuration;
import android.content.Intent;
import android.os.Bundle;
import com.reactnativenavigation.NavigationActivity;
import com.facebook.react.ReactActivityDelegate;
import com.facebook.react.ReactRootView;
import com.swmansion.gesturehandler.react.RNGestureHandlerEnabledRootView;
import expo.modules.splashscreen.singletons.SplashScreen;
import expo.modules.splashscreen.SplashScreenImageResizeMode;


public class MainActivity extends NavigationActivity {

    // Added automatically by Expo Config
    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        Intent intent = new Intent("onConfigurationChanged");
        intent.putExtra("newConfig", newConfig);
        sendBroadcast(intent);
    }



  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(null);
    // SplashScreen.show(...) has to be called after super.onCreate(...)
    // Below line is handled by '@expo/configure-splash-screen' command and it's discouraged to modify it manually
    SplashScreen.show(this, SplashScreenImageResizeMode.CONTAIN, ReactRootView.class, false);
  }

     @Override
     protected ReactActivityDelegate createReactActivityDelegate() {
         return new ReactActivityDelegate(this, getMainComponentName()) {
             @Override
             protected ReactRootView createRootView() {
                 return new RNGestureHandlerEnabledRootView(MainActivity.this);
             }
         };
     }
}

Answer 1

解决方案就是按照错误所说的去做：

删除覆盖标签 && 添加：

 protected String getMainComponentName() {
        return "App"; // here
    }
