Java 如何使用AmazonSClient避免Android 9中的应用程序崩溃？

在Android 9 API 28中，我的应用程序在API 26中创建新的AmazonSClient时崩溃，我没有收到任何错误：

AmazonSNSClient pushClient = new AmazonSNSClient(credentialsProvider);

我的日志说：

与：

该应用程序现在运行良好，但我无法生成已签名的APK，因为我 DuplicatePlatformClasses错误：重复的平台类和 我的皮棉报告说：

commons日志定义了与现在的类冲突的类 由Android提供。解决方案包括查找更新的版本或 没有相同问题的替代库，例如， 对于httpclient，请改用HttpUrlConnection或okhttp，或 使用类似jar的东西重新打包库。有一个 不仅复制功能的库的数量 Android平台，但使用的类名与 在Android中提供-例如apache http类。这个可以 导致意外事故

要解决这个问题，您需要找到库的更新版本 它不再有这个问题，或者重新打包库和所有 使用类似于jarjar工具的东西来定义它的依赖关系，或者最后， 重写代码以使用不同的API，例如http代码， 考虑使用HTTurpLink或像OKHTTP这样的库。注：此 该问题在Android Studio中具有关联的快速修复操作，并且 IntelliJ想法。要抑制此错误，请使用问题id DuplicatePlatformClass，如抑制警告中所述 和错误部分

因此，我在我的项目文件夹的终端中运行了gradlew app:dependencies>dependencies.txt，发现com.amazonaws:aws android sdk sns:2.2.0使用commons logging:commons logging:1.1.1，但我也可以找到commons logging:commons logging:1.2，我想这是安卓提供的

---

那么为什么com.amazonaws:aws-android-sdk-sns:2.2.0不使用commons-logging:commons-logging:1.2，如果我排除commons-logging:commons-logging:1.1，那么我该如何解决这个问题呢？

我可以通过将com.amazonaws:aws-android-sdk-sns:2.2.0更新到我的com.amazonaws:aws-android-sdk-sns:2.9.1版本来解决这个问题

本期还跟踪了Android 9中的NoClassDefFoundError：

从不->更新。此问题已在SDK的2.6.30版本中修复。

implementation 'com.amazonaws:aws-android-sdk-sns:2.2.0', {
    exclude module: 'commons-logging'
}

implementation 'com.amazonaws:aws-android-sdk-sns:2.2.0'
