Java 带有AWS（亚马逊服务sdk）的Proguard reutrn错误代码1

下面是我如何编辑proguard.txt的。在导出apk之前，我还需要做其他事情吗？因为它现在在proguard中返回错误代码1

-keep class com.facebook.** { *; }
-keep public class com.google.** { *; }
-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.**
-dontwarn org.codehaus.jackson.**
-dontwarn org.apache.commons.logging.impl.**
-dontwarn org.apache.http.conn.scheme.**
-dontwarn com.amazonaws.services.securitytoken.**

这里是错误

感谢您的帮助

如果您的应用程序在调试模式下工作，尽管列出了缺少的类，您也可以忽略其余的警告：

-dontwarn com.amazonaws.**

在我的情况下，如果我简单地停止工作，它将崩溃

我添加了以下内容来保持该类，到目前为止，它仍然有效

-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.convert.*                          { *; }
-keepattributes Signature,*Annotation*,EnclosingMethod
-keepnames class com.fasterxml.jackson.** { *; }
-keepnames class com.amazonaws.** { *; }
