android - Proguard Aws s3问题

在尝试为amazon s3实现proguard时遇到了一个真正的问题，它在第29行加载应用程序时不断崩溃，这是

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

这是错误的堆栈跟踪，不确定诚实意味着什么，以任何方式获得更好的堆栈跟踪或任何关于如何修复它的建议？

这是我的proguard.cfg

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

-keep public class com.google.vending.licensing.ILicensingService
-keep public class com.android.vending.licensing.ILicensingService
-keep public class org.apache.commons.** { *; }
-keep public class * extends android.app.Application
-keepnames class org.codehaus.jackson.** { *; }
-keepclassmembers class com.amazonaws.** { *; }

-keepclassmembers class com.closr.closr.** {
public static <fields>;
}

-keepclasseswithmembernames class * {
native <methods>;
}
-keepclassmembers public class * extends android.view.View {
 void set*(***);
 *** get*();
}
-keepclassmembers class * extends android.app.Activity {
  public void *(android.view.View);
}
-keepclassmembers enum * {
 public static **[] values();
 public static ** valueOf(java.lang.String);
}
 -keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}
-keepclassmembers class **.R$* {
  public static <fields>;
}

最佳答案

很抱歉你遇到麻烦了。看起来您还没有尝试使用aws示例中提供的proguard配置。它可能仍然不能解决你的问题，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

请告诉我，如果使用后仍然给你带来麻烦。
