我正在使用Jackson JSON处理器来处理我的应用程序

compile 'com.fasterxml.jackson.core:jackson-databind:2.4.2'
compile 'com.fasterxml.jackson.core:jackson-annotations:2.4.2'.

而我的proguard配置是。

## BEGIN -- Google Play Services proguard.txt
-keep class * extends java.util.ListResourceBundle {
    protected java.lang.Object[][] getContents();
}
# Keep SafeParcelable value, needed for reflection. This is required to support backwards
# compatibility of some classes.
-keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable {
    public static final *** NULL;
}
# Keep the names of classes/members we need for client functionality.
-keepnames @com.google.android.gms.common.annotation.KeepName class *
-keepclassmembernames class * {
    @com.google.android.gms.common.annotation.KeepName *;
}
# Needed for Parcelable/SafeParcelable Creators to not get stripped
-keepnames class * implements android.os.Parcelable {
    public static final ** CREATOR;
}
## END -- Google Play Services proguard.txt

-keepattributes Signature,RuntimeVisibleAnnotations,AnnotationDefault

-dontskipnonpubliclibraryclassmembers
-dontskipnonpubliclibraryclasses
-keepattributes *Annotation*.
-keep class org.codehaus.jackson.**




-dontwarn twitter4j.**
-dontwarn com.facebook.android.BuildConfig
-dontwarn org.apache.commons.**
-keep class org.apache.http.** { *; }
-dontwarn org.apache.http.**
-dontwarn com.nhaarman.listviewanimations.**

但是,当我尝试在调试模式下编译时出现以下错误。

26207-26207/com.blah E/AndroidRuntime﹕ FATAL EXCEPTION: main
    Process: com.blah, PID: 26207
    java.lang.NoSuchFieldError: PUBLIC_ONLY

经过很多调试后,终于找到了我的Proguard配置的答案

-keepattributes *Annotation*,EnclosingMethod,Signature
-keepnames class com.fasterxml.jackson.** { *; }
-dontwarn com.fasterxml.jackson.databind.**
-keep class org.codehaus.** { *; }
-keepclassmembers public final enum org.codehaus.jackson.annotate.JsonAutoDetect$Visibility {
    public static final org.codehaus.jackson.annotate.JsonAutoDetect$Visibility *; }
-keep public class your.class.** {
    public void set*(***);
    public *** get*();
}

你的课程描述了你用来解析你的回应的getter setter类/类。

此外,我添加compile 'com.fasterxml.jackson.core:jackson-core:2.4.2' 到我以前遗漏的Gradle文件。现在我的Proguard就像一只野兽...... ;-)

为我修改了@goonerDroid作品中的一小部分

-keepattributes *Annotation*,EnclosingMethod,Signature
-keepnames class com.fasterxml.jackson.** { *; }
-dontwarn com.fasterxml.jackson.databind.**
-keep class org.codehaus.** { *; }
-keepclassmembers public final enum org.codehaus.jackson.annotate.JsonAutoDetect$Visibility {
    public static final org.codehaus.jackson.annotate.JsonAutoDetect$Visibility *; }
-keep public class your.class.** {
    *;
}
