混淆Android代码的错误

Question

我有一个混淆Android代码的问题。我使用Proguard 4.7版和Eclipse作为我的IDE。我改变了我的proguard.cfg这样：

-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.Service 
-keep public class * extends android.content.BroadcastReceiver 
-keep public class * extends android.content.ContentProvider 
-keep public class * implements android.view.View.OnTouchListener 
-keep 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*(...); 
} 
-keep class * extends android.preference.Preference { 
    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*(...); 
}  
# LVL License binder class 
-keep class com.android.vending.licensing.ILicensingService  
# This is necessary for LVL among others. According to proguard doc java accesses enum fields by introspection. 
-keepclassmembers enum * { 
    public static **[] values(); 
    public static ** valueOf(java.lang.String); 
} 
#Optimization settings 
-dontoptimize 

当我编译我的项目，我得到一个错误，我解决不了。这是错误：

Unable to execute dex: Multiple dex files define Lchangebackground/app/OnSwipeListener 
Conversion to Dalvik Format failed: Unable to execute dex: Multiple dex files define Lchangebackground/app/OnSwipeListener

这通常意味着你包括一个库两次，或者你的类路径的其他问题。把所有的罐子放在libs下并清理你的项目。检查相同库的不同版本，并通过引用的库项目包括库。
