为android项目使用proguard总是出错？

Question

我在使用 proguard 时遇到问题，这是我第一次学习 proguard，我使用 this 和更多链接来制作 proguard 但我无法实施到我的项目中，在我的应用程序中我使用库 google_play_services 和 actionbarsherlock .我一直在尝试，结果总是错误。我花了 2 天时间寻找如何在我的项目中使用 proguard，这次我真的很困惑，我的应用程序中需要 proguard，我的应用程序的屏幕截图（app_run）。

这是我的 proguard 设置

    -optimizationpasses 5

    #When not preverifing in a case-insensitive filing system, such as Windows. Because this tool unpacks your processed jars, you should then use:
    -dontusemixedcaseclassnames

    #Specifies not to ignore non-public library classes. As of version 4.5, this is the default setting
    -dontskipnonpubliclibraryclasses

    #Preverification is irrelevant for the dex compiler and the Dalvik VM, so we can switch it off with the -dontpreverify option.
    -dontpreverify

    #Specifies to write out some more information during processing. If the program terminates with an exception, this option will print out the entire stack trace, instead of just the exception message.
    -verbose

    #The -optimizations option disables some arithmetic simplifications that Dalvik 1.0 and 1.5 can't handle. Note that the Dalvik VM also can't handle aggressive overloading (of static fields).
    #To understand or change this check http://proguard.sourceforge.net/index.html#/manual/optimizations.html
    -optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

    #To repackage classes on a single package
    #-repackageclasses ''

    #Uncomment if using annotations to keep them.
    #-keepattributes *Annotation*

    #Keep classes that are referenced on the AndroidManifest
    -keep public class * extends android.app.Activity
    -keep public class * extends android.app.Application
    -keep public class * extends android.app.Service
    -keep public class * extends android.content.BroadcastReceiver
    -keep public class * extends android.content.ContentProvider
    -keep public class com.android.vending.licensing.ILicensingService


    #To remove debug logs:
    -assumenosideeffects class android.util.Log {
        public static *** d(...);
        public static *** v(...);
        public static *** i(...);
    }

## ActionBarSherlock 4.4.0 specific rules ##

-keep class android.support.v4.app.** { *; }
-keep interface android.support.v4.app.** { *; }
-keep class com.actionbarsherlock.** { *; }
-keep interface com.actionbarsherlock.** { *; }
-keepattributes *Annotation*

## hack for Actionbarsherlock 4.4.0, see https://github.com/JakeWharton/ActionBarSherlock/issues/1001 ##
-dontwarn com.actionbarsherlock.internal.**

## Google Play Services 4.3.23 specific rules ##
## https://developer.android.com/google/play-services/setup.html#Proguard ##

-keep class * extends java.util.ListResourceBundle {
    protected Object[][] getContents();
}

-keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable {

}

-keepnames @com.google.android.gms.common.annotation.KeepName class *
-keepclassmembernames class * {
    @com.google.android.gms.common.annotation.KeepName *;
}

-keepnames class * implements android.os.Parcelable {
    public static final ** CREATOR;
}


    #To avoid changing names of methods invoked on layout's onClick.
    # Uncomment and add specific method names if using onClick on layouts
    #-keepclassmembers class * {
    # public void onClickButton(android.view.View);
    #}

    #Maintain java native methods 
    -keepclasseswithmembernames class * {
        native <methods>;
    }

    #To maintain custom components names that are used on layouts XML.
    #Uncomment if having any problem with the approach below
    #-keep public class custom.components.package.and.name.**

    #To maintain custom components names that are used on layouts XML:
    -keep public class * extends android.view.View {
        public <init>(android.content.Context);
        public <init>(android.content.Context, android.util.AttributeSet);
        public <init>(android.content.Context, android.util.AttributeSet, int);
        public void set*(...);
    }

    -keepclasseswithmembers class * {
        public <init>(android.content.Context, android.util.AttributeSet);
    }

    -keepclasseswithmembers class * {
        public <init>(android.content.Context, android.util.AttributeSet, int);
    }

    #Maintain enums
    -keepclassmembers enum * {
        public static **[] values();
        public static ** valueOf(java.lang.String);
    }

    #To keep parcelable classes (to serialize - deserialize objects to sent through Intents)
    -keep class * implements android.os.Parcelable {
      public static final android.os.Parcelable$Creator *;
    }

    #Keep the R
    -keepclassmembers class **.R$* {
        public static <fields>;
    }

谁能帮我介绍一下如何在我的应用程序中使用 proguard？

真的需要帮助，谢谢

Proguard 将需要您使用的库的“规则”，也可能需要您自己的代码。其中很多规则可以在https://github.com/krschultz/android-proguard-snippets/tree/master/libraries找到
