java - React Native : error: cannot find symbol > new AppCenterReactNativeAnalyticsPackage(MainApplication. 这个

Question

在我添加这些之前，我在 React Native 中使用 android 成功构建:

"appcenter-analytics": "2.1.0",
    "appcenter-crashes": "2.1.0",

我在:

"react": "16.8.6",
    "react-native": "0.60.4",

错误是:

显然，这个 android/app/build/generated/rncli/src/main/java/com/facebook/react/PackageList.java 文件在旧版本中不存在应用:

package com.facebook.react;

import android.app.Application;
import android.content.Context;
import android.content.res.Resources;

import com.facebook.react.ReactPackage;
import com.facebook.react.shell.MainReactPackage;
import java.util.Arrays;
import java.util.ArrayList;

import com.nfibengage.BuildConfig;
import com.nfibengage.R;

// @react-native-community/async-storage
import com.reactnativecommunity.asyncstorage.AsyncStoragePackage;
// appcenter-analytics
import com.microsoft.appcenter.reactnative.analytics.AppCenterReactNativeAnalyticsPackage;
// appcenter-crashes
import com.microsoft.appcenter.reactnative.crashes.AppCenterReactNativeCrashesPackage;
// react-native-sentry
import io.sentry.RNSentryPackage;
// react-native-splash-screen
import org.devio.rn.splashscreen.SplashScreenReactPackage;

public class PackageList {
  private Application application;
  private ReactNativeHost reactNativeHost;
  public PackageList(ReactNativeHost reactNativeHost) {
    this.reactNativeHost = reactNativeHost;
  }

  public PackageList(Application application) {
    this.reactNativeHost = null;
    this.application = application;
  }

  private ReactNativeHost getReactNativeHost() {
    return this.reactNativeHost;
  }

  private Resources getResources() {
    return this.getApplication().getResources();
  }

  private Application getApplication() {
    if (this.reactNativeHost == null) return this.application;
    return this.reactNativeHost.getApplication();
  }

  private Context getApplicationContext() {
    return this.getApplication().getApplicationContext();
  }

  public ArrayList<ReactPackage> getPackages() {
    return new ArrayList<>(Arrays.<ReactPackage>asList(
      new MainReactPackage(),
      new AsyncStoragePackage(),
      new AppCenterReactNativeAnalyticsPackage(MainApplication.this, getResources().getString(R.string.appCenterAnalytics_whenToEnableAnalytics)),
      new AppCenterReactNativeCrashesPackage(MainApplication.this, getResources().getString(R.string.appCenterCrashes_whenToSendCrashes)),
      new RNSentryPackage(),
      new SplashScreenReactPackage()
    ));
  }
}

MainApplication.java 文件位于 android/main/java/com/nfibengage/MainApplication.java 中:

package com.nfibengage;

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);
  }
}

我尝试将它导入到 PackageList.java 中，如下所示:

import com.nfibengage.MainApplication;

但我继续得到同样的错误。如果有人能告诉我这个 PackageList.java 文件是从哪里来的，我如何才能让它再次工作，而不是完全删除 appcenter-analytics 和 appcenter -崩溃。

请确保您的安装顺序与以下相同。

添加 App Center SDK 模块

npm install appcenter appcenter-analytics appcenter-crashes --save-exact

或

yarn add appcenter appcenter-analytics appcenter-crashes --exact

自动集成SDK

react-native link appcenter
react-native link appcenter-analytics
react-native link appcenter-crashes

App Center SDK 不会在链接过程中自动为 App Center 模块设置模拟。如果您在应用程序中使用 Jest 测试框架，并且在使用 Jest 运行测试时遇到由 App Center SDK 引起的错误，请将以下内容添加到 的 jest 部分package.json 文件(仅包含正在使用的模块):

"setupFiles": [
   "<rootDir>/node_modules/appcenter/test/AppCenterMock.js",
   "<rootDir>/node_modules/appcenter-analytics/test/AppCenterAnalyticsMock.js",
   "<rootDir>/node_modules/appcenter-crashes/test/AppCenterCrashesMock.js",
   "<rootDir>/node_modules/appcenter-push/test/AppCenterPushMock.js"
]

编辑项目的 android/app/src/main/assets/appcenter-config.json 并将 YOUR_APP_SECRET 占位符值替换为您的 App Center 项目的应用程序 secret 。
