Question

在我的Android应用中，我遇到了异常：

java.lang.IllegalStateException: Conflicting property name definitions: 
  'keywords' (for [field com.myapp.d.q#a]) vs 'download_urls' 
  (for [method com.myapp.d.q#a(1 params)])

但是当我对我的代码进行模糊处理时，我在调试模式下运行代码时不会遇到此异常。我在SO上阅读了几个回复，并对proguard.cfg文件做了很多编辑，这就是它的外观：

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

-dontwarn android.text.*

}

# Custom view components might be accessed from your layout files
-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet, int);
}

# event handlers can be specified in the layout files e.g. android:onClick="nextButton_onClick"
-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

-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 public class com.crittercism.* {
    *;
}

-keepnames class com.fasterxml.jackson.** { 
    *; 
}

但我无法解决这个问题。我在这里做错了什么？我正在使用杰克逊2.1.2罐子

Answer 1

修改proguard配置以包括“处理bean类”中提到的内容以及在POJO中指定jsonignoreproperties的组合确保我可以通过错误并创建一个带有混淆的APK。

Answer 2

首先，异常信息是obfscate，使用Retrace工具和Proguard读取带有原始名称的消息。并再次发布异常消息。

杰克逊和ProGuard
