问题描述
我最近更新为 React Native@0.60.4
.
该应用程序可以在iOS和xcode上编译并正常运行.但是,当我尝试运行新的android代码时,遇到以下错误:
The app compiles and works fine on iOS and xcode. However, when I try and run the new android code I face the following error:

import com.facebook.react.PackageList;
^
symbol: class PackageList
location: package com.facebook.react
/redacted/MainApplication.java:28: error: cannot find symbol
List<ReactPackage> packages = new PackageList(this).getPackages();
^
symbol: class PackageList
2 errors

这是我的MainApplication.java
This is my MainApplication.java
package com.my.app;
import android.app.Application;
import android.util.Log;
import com.facebook.react.PackageList;
import com.facebook.hermes.reactexecutor.HermesExecutorFactory;
import com.facebook.react.bridge.JavaScriptExecutorFactory;
import com.facebook.react.ReactApplication;
import com.facebook.react.ReactNativeHost;
import com.facebook.react.ReactPackage;
import com.facebook.soloader.SoLoader;
import java.util.List;
public class MainApplication extends Application implements ReactApplication {
private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {
@Override
public boolean getUseDeveloperSupport() {
return BuildConfig.DEBUG;
}
@Override
protected List<ReactPackage> getPackages() {
@SuppressWarnings("UnnecessaryLocalVariable")
List<ReactPackage> packages = new PackageList(this).getPackages();
// Packages that cannot be autolinked yet can be added manually here, for example:
// packages.add(new MyReactNativePackage());
return packages;
}
@Override
protected String getJSMainModuleName() {
return "index";
}
};
@Override
public ReactNativeHost getReactNativeHost() {
return mReactNativeHost;
}
@Override
public void onCreate() {
super.onCreate();
SoLoader.init(this, /* native exopackage */ false);
}
}
