React Native: error: cannot find symbol > new AppCenterReactNativeAnalyticsPackage(MainApplication.this

Daniel :

I was getting a successful build with android in React Native until I added these:

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

I am on:

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

The error is:

Error: Command failed: ./gradlew app:installDebug -PreactNativeDevServerPort=8081 Note: /Users/danale/Projects/NFIBEngage/node_modules/react-native-sentry/android/src/main/java/io/sentry/RNSentryModule.java uses or overrides a deprecated API.

  Compilation failed; see the compiler error output for details.

Apparently there is this android/app/build/generated/rncli/src/main/java/com/facebook/react/PackageList.java file that did not exist with the legacy version of this application:

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()
    ));
  }
}

The MainApplication.java file is inside of android/main/java/com/nfibengage/MainApplication.java:

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);
  }
}

I tried importing it into PackageList.java like so:

import com.nfibengage.MainApplication;

but I continue to get the same error. If anyone can walk me through where did this PackageList.java file come from and how do I get this working again short of just completely removing appcenter-analytics and appcenter-crashes.

hong developer :

Please make sure your installation order is the same as the following.

Add the App Center SDK modules

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

or

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

Integrate the SDK automatically

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

App Center SDK does not set up mocks automatically for App Center modules during the linking process. If you are using Jest test framework in your application and experience errors caused by the App Center SDK while running tests with Jest, add the following to the jest section of package.json file (include only modules in use):

"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"
]

Edit the project's android/app/src/main/assets/appcenter-config.json and replace the YOUR_APP_SECRET placeholder value with your App Center project's application secret.
