java - 如何使用 AmazonSNSClient 避免 Android 9 中的应用程序崩溃？

Question

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

AmazonSNSClient pushClient = new AmazonSNSClient(credentialsProvider);

我的 LogCat 说:

我发现，如果我不从 build.gradle 中的“com.amazonaws:aws-android-sdk-sns”中排除“commons-logging”，就可以避免该错误，因此我替换了:

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

与:

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

该应用程序现在工作正常，但我无法构建签名的 APK，因为我得到错误“DuplicatePlatformClasses:重复平台类”和我的 Lint 报告说:

commons-logging defines classes that conflict with classes now provided by Android. Solutions include finding newer versions or alternative libraries that don't have the same problem (for example, for httpclient use HttpUrlConnection or okhttp instead), or repackaging the library using something like jarjar. There are a number of libraries that duplicate not just functionality of the Android platform but using the exact same class names as the ones provided in Android -- for example the apache http classes. This can lead to unexpected crashes.

To solve this, you need to either find a newer version of the library which no longer has this problem, or to repackage the library (and all of its dependencies) using something like the jarjar tool, or finally, rewriting the code to use different APIs (for example, for http code, consider using HttpUrlConnection or a library like okhttp). Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA. To suppress this error, use the issue id "DuplicatePlatformClasses" as explained in the Suppressing Warnings and Errors section.

因此，我在项目文件夹的终端中运行“gradlew app:dependencies > dependency.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”，我猜它是“由 Android 提供的”？

那么，如果我排除“commons-logging:commons-logging:1.1”，为什么“com.amazonaws:aws-android-sdk-sns:2.2.0”不使用“commons-logging:commons-logging:1.2”。 1”，我该如何解决这个问题？

Answer 1

我可以通过将“com.amazonaws:aws-android-sdk-sns:2.2.0”更新到较新的版本来解决该错误(在我的例子中为“com.amazonaws:aws-android-sdk-sns:2.9”)。 1”)。
