工程中使用了fastjson，无奈，对工程做混淆的时候总是报错过不去，后来过去了又出现使用fastjson的地方数据不正确的问题，试了好多办法才成功，废话不多说，添加的代码：
##---------------Begin: proguard configuration for fastjson ----------
#-keepnames class * implements java.io.Serializable
-keep public class * implements java.io.Serializable {
public *;
}
-keepclassmembers class * implements java.io.Serializable {
static final long serialVersionUID;
private 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();
}
-dontwarn android.support.**
-dontwarn com.alibaba.fastjson.**
-dontskipnonpubliclibraryclassmembers
-dontskipnonpubliclibraryclasses
-libraryjars libs/fastjson.jar
-keep class com.alibaba.fastjson.** { *; }
-keepclassmembers class * {
public <methods>;
}
##---------------End: proguard configuration for fastjson ----------Gson的混淆：
##---------------Begin: proguard configuration for Gson ----------
# Gson uses generic type information stored in a class file when working with fields. Proguard
# removes such information by default,so configure it to keep all of it.
-keepattributes Signature
# For using GSON @Expose annotation
-keepattributes *Annotation*
# Gson specific classes
-keep class sun.misc.Unsafe { *; }
#-keep class com.google.gson.stream.** { *; }
# Application classes that will be serialized/deserialized over Gson
-keep class cn.howie.base.data.** { *; } -keep class cn.howie.base.bean.** { *; }
##---------------End: proguard configuration for Gson ----------其中红色部分必须为自己项目中的实体类，否则混淆后无法正常显示数据，网上有好多博客都很坑，直接把google文档的代码直接贴出来了，一定要修改红色部分。
