由于Amazon AWS SDK出现问题，启用ProGuard后，我的Android应用无法从Eclipse导出。
我正在使用适用于Android的AWS SDK 1.7.0版（核心版和s3版）。记录到控制台的错误如下所示。
我按照亚马逊提供的推荐ProGuard配置设置无效：https://mobile.awsblog.com/post/Tx2OC71PFCTC63E/Using-ProGuard-with-the-AWS-SDK-for-Android
这些是我项目中的罐子：
aws-android-sdk-1.7.0-core.jar
aws-android-sdk-1.7.0-s3.jar
Project.properties：
proguard.config=proguard-project.txt
# Project target.

android.library.reference.2=../../../../../opt/ADT/sdk/extras/android/support/v7/appcompat
我的ProGuard配置如下：

如果我添加
-dontwarn com.amazonaws.**
ProGuard正常工作，但是当我运行应用程序时，它立即关闭此RuntimeException：

有什么想法吗？我几个小时都坚持这个问题。
答案 0 :(得分：0)
问题不在于Proguard，而是缺少区域配置文件。确保它在最终jar的类路径中可用。
