我的React Native Android项目遇到了问题。我目前正在集成AWS Amplify推送通知。我收到以下"；重复类"依赖性错误，我不知道它可能来自哪里。你有解决这个问题的办法吗？
我已经做了什么：
- 我在这里找到了这张票https://github.com/facebook/react-native/issues/27493这似乎表明使用react原生设备信息可能存在问题，我就是这样。所以我删除了这个库，用react原生版本信息替换它。但问题依然存在
- 我查过这张票https://github.com/dantasfiles/AmplifyAndroidPush/issues/1-当运行
./gradlew :app:dependencies > ../dependencies.txt时，我得到了依赖树，可以看到com.firebase:firebase-jobdispatcher:0.6.0似乎只被aws放大推送通知使用。但我现在仍然不知道该怎么办：
+--- project :aws-amplify_pushnotification
...
| --- com.firebase:firebase-jobdispatcher:0.6.0
有人已经面对这个问题并知道解决方案吗？
提前感谢！

GitHub上也有一个关于这个问题的bug，但这个bug已经关闭，没有实际的解决方案：(https://github.com/aws-amplify/amplify-js/issues/4593
如果同一个包中有两个不同的版本，可能会发生这种情况，例如，这将导致错误：
implementation 'com.google.android.gms:play-services-analytics:17.0.0'
implementation 'com.google.android.gms:play-services-tagmanager:17.0.1'
要解决这个问题，只需使两者的版本相同即可：
implementation 'com.google.android.gms:play-services-analytics:17.0.0'
implementation 'com.google.android.gms:play-services-tagmanager:17.0.0'
Hi-stackoverflow社区，
经过大约一周的调查，并在aws-amplified-js-github项目中打开了一张罚单，我现在能够解决这个问题了。在下文中，如果你们中的任何人将来可能面临同样的问题，我想描述解决方案。
这是我在aws-amplifier js上创建的github票证：https://github.com/aws-amplify/amplify-js/issues/8389
在我的应用程序/build.gradle中，我有以下与firebase和播放服务相关的定义：
// Import the BoM for the Firebase platform
implementation platform('com.google.firebase:firebase-bom:28.0.1')
// Declare the dependencies for the Firebase Cloud Messaging and Analytics libraries
// When using the BoM, you don't specify versions in Firebase library dependencies
implementation 'com.google.firebase:firebase-messaging'
implementation 'com.google.firebase:firebase-analytics'
implementation "com.google.android.gms:play-services-gcm:17.0.0"
...
configurations.all {
resolutionStrategy {
force 'com.google.android.gms:play-services-gcm:16.1.0'
force 'com.google.android.gms:play-services-base:16.1.0'
force 'com.google.firebase:firebase-core:16.0.6'
force 'com.google.firebase:firebase-messaging:17.6.0'
}
}
我从不同的资源中获得了这些定义，解释了如何集成aws放大推送通知和分析。
仅用以下两行代码替换所有这些定义就成功了，并允许我再次构建我的Android应用程序，而不会出现重复的类错误：
implementation "com.google.firebase:firebase-core:15.0.2"
implementation "com.google.firebase:firebase-messaging:15.0.2"
