这是我的proguard配置

here is my proguard config

-injars      bin/classes
-injars      libs
-outjars     bin/classes-processed.jar

-libraryjars /libs/android-support-v13.jar



#
# This ProGuard configuration file illustrates how to process Android
# applications.
# Usage:
#     java -jar proguard.jar @android.pro
#
# If you're using the Android SDK (version 2.3 or higher), the android tool
# already creates a file like this in your project, called proguard.cfg.
# It should contain the settings of this file, minus the input and output paths
# (-injars, -outjars, -libraryjars, -printmapping, and -printseeds).
# The generated Ant build file automatically sets these paths.

# Specify the input jars, output jars, and library jars.
# Note that ProGuard works with Java bytecode (.class),
# before the dex compiler converts it into Dalvik code (.dex).



    # Save the obfuscation mapping to a file, so you can de-obfuscate any stack
    # traces later on.

    -printmapping bin/classes-processed.map

    # You can print out the seeds that are matching the keep options below.

    #-printseeds bin/classes-processed.seeds

    # Preverification is irrelevant for the dex compiler and the Dalvik VM.

    -dontpreverify

    # Reduce the size of the output some more.

    -repackageclasses ''
    -allowaccessmodification

    # Switch off some optimizations that trip older versions of the Dalvik VM.

    -optimizations !code/simplification/arithmetic

    # Keep a fixed source file attribute and all line number tables to get line
    # numbers in the stack traces.
    # You can comment this out if you're not interested in stack traces.

    -renamesourcefileattribute SourceFile
    -keepattributes SourceFile,LineNumberTable

    # RemoteViews might need annotations.

    -keepattributes *Annotation*

    # Preserve all fundamental application classes.

    -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

    # Preserve all View implementations, their special context constructors, and
    # their setters.

    -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*(...);
    }

    # Preserve all classes that have special context constructors, and the
    # constructors themselves.

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

    # Preserve all classes that have special context constructors, and the
    # constructors themselves.

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

    # Preserve the special fields of all Parcelable implementations.

    -keepclassmembers class * implements android.os.Parcelable {
        static android.os.Parcelable$Creator CREATOR;
    }

    # Preserve static fields of inner classes of R classes that might be accessed
    # through introspection.

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

    # Preserve the required interface from the License Verification Library
    # (but don't nag the developer if the library is not used at all).

    #-keep public interface com.android.vending.licensing.ILicensingService

    #-dontnote com.android.vending.licensing.ILicensingService

    # The Android Compatibility library references some classes that may not be
    # present in all versions of the API, but we know that's ok.

    -dontwarn android.support.**

    # Preserve all native method names and the names of their classes.

    -keepclasseswithmembernames class * {
        native <methods>;
    }

    # Preserve the special static methods that are required in all enumeration
    # classes.

    -keepclassmembers class * extends java.lang.Enum {
        public static **[] values();
        public static ** valueOf(java.lang.String);
    }

    # Explicitly preserve all serialization members. The Serializable interface
    # is only a marker interface, so it wouldn't save them.
    # You can comment this out if your application doesn't use serialization.
    # If your code contains serializable classes that have to be backward 
    # compatible, please refer to the manual.

    #-keepclassmembers class * implements java.io.Serializable {
    #    static final long serialVersionUID;
    #    static final java.io.ObjectStreamField[] serialPersistentFields;
    #    private void writeObject(java.io.ObjectOutputStream);
    #    private void readObject(java.io.ObjectInputStream);
    #    java.lang.Object writeReplace();
    #    java.lang.Object readResolve();
    #}

    # Your application may contain more items that need to be preserved; 
    # typically classes that are dynamically created using Class.forName:

    # -keep public class mypackage.MyClass
    # -keep public interface mypackage.MyInterface
    # -keep public class * implements mypackage.MyInterface

    # Needed by google-api-client to keep generic types and @Key annotations accessed via reflection
    -keepclassmembers class * {
      @com.google.api.client.util.Key <fields>;
    }

    -keepattributes Signature,RuntimeVisibleAnnotations,AnnotationDefault,*Annotation*

    -dontwarn sun.misc.Unsafe





    -keepattributes 
    -dontoptimize


    #-dontshrink

推荐答案

尝试关闭更多可能会破坏Dalvik的优化.经过进一步检查，您似乎实际上是在禁用所有优化.

Try turning off more optimizations that might be blowing up Dalvik. Upon further inspection it looks like you're disabling all optimizations actually.

-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

也请尝试保留这些..

-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class com.android.vending.licensing.ILicensingService

这是我的proguard文件，想知道是否只需将其替换即可.它是ADT生成的默认文件，因此这里没有什么特别的.

Here is my proguard file, wonder if just replacing it will work. Its the default file generated by by ADT so nothing special here.

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-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 * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class com.android.vending.licensing.ILicensingService

-keepclasseswithmembernames class * {
    native <methods>;
}

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

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

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

-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}
