android - 使用 AWS SDK 的 ProGuard

Question

由于 Amazon AWS SDK 的问题，当启用 ProGuard 时，我的 Android 应用无法从 Eclipse 导出。

我使用的是适用于 Android 的 AWS SDK 1.6.1 版。

记录到控制台的错误如下所示。

我遵循了 Amazon 提供的推荐 ProGuard 配置设置，但无济于事:https://mobile.awsblog.com/post/Tx2OC71PFCTC63E/Using-ProGuard-with-the-AWS-SDK-for-Android

我也试过在 ProGuard 配置中排除 Amazon 类，但这也不起作用。

无论其值(value)如何，我已经下载了 Amazon 自己的示例项目并按照他们的说明启用了 ProGuard，但在导出项目时我收到了相同的 ProGuard 错误。

谁能告诉我一个有效的 ProGuard 配置以用于 AWS SDK？

这些是我项目中的 jar :

Simpl3r-1.0.2.jar
aws-android-sdk-1.6.1-core.jar
androidplot-core-0.6.0-sources.jar
universal-image-loader-1.8.6-with-sources.jar
android_lvl.jar
androidplot-core-0.6.0-javadoc.jar
androidplot-core-0.6.0.jar
gson-2.2.4.jar
date4j.jar
crittercism_v3_0_3_sdkonly.jar
aws-android-sdk-1.6.1-s3.jar 
android-support-v7-appcompat.jar
CWAC-AdapterWrapper.jar 
cwac-endless-master.jar
android-support-v4.jar

我的 ProGuard 配置如下:

-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-verbose
-dontoptimize
-dontpreverify

-keepattributes *Annotation*
-keep public class com.google.vending.licensing.ILicensingService
-keep public class com.android.vending.licensing.ILicensingService

# For native methods, see http://proguard.sourceforge.net/manual/examples.html#native
-keepclasseswithmembernames class * {
    native <methods>;
}

# keep setters in Views so that animations can still work.
# see http://proguard.sourceforge.net/manual/examples.html#beans
-keepclassmembers public class * extends android.view.View {
   void set*(***);
   *** get*();
}

# We want to keep methods in Activity that could be used in the XML attribute onClick
-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

# For enumeration classes, see http://proguard.sourceforge.net/manual/examples.html#enumerations
-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>;
}

# The support library contains references to newer platform versions.
# Don't warn about those in case this app is linking against an older
# platform version.  We know about them, and they are safe.
-dontwarn android.support.**


# AWS:
-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.**

Answer 1

AmazonAWS 引用的缺失 Apache 注释可能是无害的。您可以告诉 ProGuard 忽略该问题:

-dontwarn org.apache.http.annotation.**

或更广泛地说，忽略库中任何 Unresolved 引用:

-dontwarn com.amazonaws.**

如 ProGuard's troubleshooting page 的链接中所述在控制台日志中，您可能可以对所有 347 个未解析的引用执行此操作，前提是您的应用程序的调试构建工作正常。
