升级到React 0.60.4导致Android构建失败（错误信息为找不到符号）。

androidreactjsreact-nativegradle

我最近已经更新到React Native@0.60.4。

该应用程序在 iOS 和 Xcode 上编译并正常工作。但是，当我尝试运行新的 Android 代码时，遇到以下错误：

/redacted/MainApplication.java:6: error: cannot find symbol
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

这是我的MainApplication.java文件。
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);
  }
}

可能是React-Native升级到0.60后找不到符号的重复问题。 - geisterfurz007
