如何避免使用AmazonSNSClient在Android 9中出現崩潰？

Question

在Android 9（API 28）中，當創建新的AmazonSNSClient時，我的應用程序崩潰（在API 26中，我沒有收到任何錯誤）：

AmazonSNSClient pushClient = new AmazonSNSClient(credentialsProvider);

我的LogCat說：

我發現如果不在build.gradle的“ com.amazonaws：aws-android-sdk-sns”中排除“ commons-logging”，就可以避免該錯誤，因此我替換為：

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

有：

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

該應用程序現在可以正常運行，但是由於出現錯誤“ DuplicatePlatformClasses：Duplicate Platform Classes”，並且我的Lint報告說：

commons-logging定義了與Android現在提供的類沖突的類。 解決方案包括查找沒有相同問題的較新版本或替代庫（例如，對於httpclient使用HttpUrlConnection或okhttp替代），或使用jarjar之類的庫重新打包該庫。 有許多庫不僅可以復制Android平台的功能，而且可以使用與Android中提供的名稱完全相同的類名稱，例如apache http類。 這可能會導致意外崩潰。

要解決此問題，您需要找到不再存在此問題的較新版本的庫，或者使用jarjar工具之類的程序重新打包該庫（及其所有依賴項），或者最后，重寫代碼以使用不同的庫。 API（例如，對於http代碼，請考慮使用HttpUrlConnection或類似okhttp的庫）。 注意：此問題在Android Studio和IntelliJ IDEA中具有關聯的quickfix操作。 若要抑制此錯誤，請使用問題ID“ DuplicatePlatformClasses”，如“抑制警告和錯誤”部分中所述。

因此，我在項目文件夾的終端中運行了“ gradlew app：dependencies> Dependencies.txt”，發現“ com.amazonaws：aws-android-sdk-sns：2.2.0”使用了“ commons-logging：commons-logging” ：1.1.1”，但我還可以找到“ commons-logging：commons-logging：1.2”，它是“由Android提供的”嗎？

因此，如果我排除“ commons-logging：commons-logging：1.1.1”，為什么“ com.amazonaws：aws-android-sdk-sns：2.2.0”不使用“ commons-logging：commons-logging：1.2”，並且我該如何解決這個問題？

Answer 1

我可以通過將“ com.amazonaws：aws-android-sdk-sns：2.2.0”更新到新版本（在我的情況下為“ com.amazonaws：aws-android-sdk-sns：2.9.1”）來解決該錯誤。 。
