android - Proguard Aws s3 问题

Question

在尝试为 amazon s3 实现混淆器时遇到了一个真正的问题，它在第 29 行加载应用程序时一直崩溃

  s3Client = new AmazonS3Client(new BasicAWSCredentials(
            Constants.ACCESS_KEY_ID, Constants.SECRET_KEY));

这是错误的堆栈跟踪，但不确定以任何方式获得更好的堆栈跟踪或关于如何修复它的任何建议的诚实意味着什么？

-dontoptimize
-dontpreverify
-dontwarn
-keepattributes *Annotation*,Exceptions,InnerClasses,Signature,Deprecated,       SourceFile,LineNumberTable,*Annotation*,EnclosingMethod

抱歉，您遇到了麻烦。看起来您还没有尝试使用 AWS 示例中提供的 Proguard 配置。它可能仍然无法解决您的问题，但值得一试。如果它仍然不起作用，我们可以尝试看看从那里去哪里，至少它可能会给你一个更好的堆栈跟踪。你可以在这里找到它: https://github.com/awslabs/aws-sdk-android-samples

Proguard 配置是..

# These options are the minimal options for a functioning application
# using Proguard and the AWS SDK for Android

-keep class org.apache.commons.logging.**               { *; }
-keep class com.amazonaws.services.sqs.QueueUrlHandler  { *; }
-keep class com.amazonaws.javax.xml.transform.sax.*     { public *; }
-keep class com.amazonaws.javax.xml.stream.**           { *; }
-keep class com.amazonaws.services.**.model.*Exception* { *; }
-keep class com.amazonaws.internal.**                                   { *; }
-keep class org.codehaus.**                             { *; }
-keep class org.joda.time.tz.Provider                    { *; }
-keep class org.joda.time.tz.NameProvider                { *; }
-keepattributes Signature,*Annotation*,EnclosingMethod
-keepnames class com.fasterxml.jackson.** { *; }
-keepnames class com.amazonaws.** { *; }

-dontwarn com.fasterxml.jackson.databind.**
-dontwarn javax.xml.stream.events.**
-dontwarn org.codehaus.jackson.**
-dontwarn org.apache.commons.logging.impl.**
-dontwarn org.apache.http.conn.scheme.**
-dontwarn org.apache.http.annotation.**
-dontwarn org.ietf.jgss.**
-dontwarn org.joda.convert.**
-dontwarn org.w3c.dom.bootstrap.**

#SDK split into multiple jars so certain classes may be referenced but not used
-dontwarn com.amazonaws.services.s3.**
-dontwarn com.amazonaws.services.sqs.**

-dontnote com.amazonaws.services.sqs.QueueUrlHandler

如果使用后仍然给您带来麻烦，请告诉我。
