Proguard Aws s3问题

Question

有一个真正的问题试图为amazon s3实现proguard它继续崩溃加载应用程序在第29行

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

这是错误的堆栈跟踪，并且不确定任何方式获得更好的堆栈跟踪或任何有关如何修复它的建议都意味着什么？

抱歉，你遇到了麻烦。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，但值得尝试一下。如果它仍然无法工作，我们可以尝试从那里去哪里，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

而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

如果在使用后仍然给您带来麻烦，请告诉我。

尝试添加此项（根据您使用的库）。

-libraryjars C:/workspace/3rd-libs/aws-android-sdk-1.5.0/lib/aws-android-sdk-1.5.0-core.jar
-libraryjars C:/workspace/3rd-libs/aws-android-sdk-1.5.0/lib/aws-android-sdk-1.5.0-s3.jar
-libraryjars C:/workspace/3rd-libs/aws-android-sdk-1.5.0/lib/aws-android-sdk-1.5.0-sdb.jar

-keep class com.amazonaws.** { *; }

-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 org.codehaus.**                             { *; }
-keepattributes Signature,*Annotation*

-dontwarn javax.xml.stream.events.**
