react-native-notifications 在 iOS 上有效，在 Android 上失败

Question

我已经安装了 react-native-notifications 并且在 iOS 上一切正常，但它在 Android 上一直给我错误。我已经按照这里的确切 Android 安装说明进行操作：https : //wix.github.io/react-native-notifications/docs/installation-android

我的开发流程：

1. 进行修改。
2. npx react-native clean-project-auto; npx react-native-clean-project
3. rm -rf android/app/build; anroid/gradlew clean; android/gradlew build --refresh-dependencies
4. npx react-native start --reset-cache
5. Android Studio 使缓存无效/重新启动。
6. Android Studio 干净构建。
7. Android Studio 同步 Gradle 文件并运行应用程序。
8. npx react-native run-android --deviceId emulator-5554

步骤 7. 结果Invariant Violation: PushNotificationManager is not available.（下图）

步骤 8. 产生以下日志：

当我将包添加packages.add(new RNNotificationsPackage(MainApplication.this))到 MainApplication.javagetPackages()方法时，它说这个包已经链接到这个错误：（下图）

E/unknown:ReactNative: Exception in native call
    java.lang.IllegalStateException: Native module RNBridgeModule tried to override RNNotificationsModule. Check the getPackages() method in MainApplication.java, it might be that module is being created twice. If this was your intention, set canOverrideExistingModule=true. This error may also be present if the package is present only once in getPackages() but is also automatically added later during build time by autolinking. Try removing the existing entry and rebuild.

        releaseImplementation files(hermesPath + "hermes-release.aar")
    } else {
        implementation jscFlavor
    }
}

android/build.gradle

buildscript {
    ext {
        buildToolsVersion = "28.0.3"
        minSdkVersion = 21
        compileSdkVersion = 28
        targetSdkVersion = 29
        supportLibVersion = "28.0.0"
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.2'
        classpath 'com.google.gms:google-services:4.3.3'  // Google Services plugin

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

我真的很想使用这个包，因为它在 iOS 上运行得非常好。有什么帮助，谢谢！

更新： 解决这个问题的方法是react-native-push-notification依赖。但是，如果react-native-notifications安装了软件包，上面的步骤 8 仍然会导致错误。我不确定它是否值得报告错误，或者是否有修复程序可以通过我的 WebStorm CLI 或类似的东西启用 Java 权限。

遇到了同样的错误，幸运的是我能够通过将 IOS 部分封装在平台检查中来修复它，例如：

if(Platform.OS === 'ios'){
    PushNotificationIOS.removeAllDeliveredNotifications();
}
