android - Proguard 使用适用于 Android 的 AWS SDK 给出错误

Question

在我的 Android 应用程序中，我使用了亚马逊的一些库:

• aws-android-sdk-cognito-2.2.2.jar,
• aws-android-sdk-core-2.2.2.jar,
• aws-android-sdk-ddb-2.2.2.jar,
• aws-android-sdk-ddb-mapper-2.2.2.jar,
• aws-android-sdk-sns-2.2.2.jar,
• aws-android-sdk-s3-2.2.2.jar

当我在启用 Proguard 和空文件 proguard-project.txt 的情况下导出 apk 文件时，我遇到了这些错误:

请帮助我如何在这种情况下配置 Proguard!

编辑:我使用 Eclipse。

Answer 1

这些警告是由于缺少类引用。 SDK 的打包方式可能会导致在 proguard 时出现警告。但是，这些未解析的类对 SDK 没有影响。您可以安全地忽略它们。这是抑制它们的最小混淆器配置。

-keep class com.amazonaws.** { *; }
-keepnames class com.amazonaws.** { *; }
-dontwarn com.amazonaws.**
-dontwarn com.fasterxml.**
