1：在build.grandle添加，其中规则写在proguard-rules.pro中
buildTypes{
release{signingConfig signingConfigs.release
minifyEnabled true
proguardFiles getDefaultProguardFile(‘proguard-android.txt‘),‘proguard-rules.pro‘
}
}
2：在proguard-rules.pro中加入以下代码（示例）
-optimizationpasses5# 指定代码的压缩级别-dontusemixedcaseclassnames# 是否使用大小写混合-dontpreverify# 混淆时是否做预校验-verbose# 混淆时是否记录日志-optimizations!code/simplification/arithmetic,!field/*,!class/merging/*# 混淆时所采用的算法-keep

##---------------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
# 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 com.xxx.xxx.xxx.bean.** { *; } ##这里需要改成解析到哪个 javabean
##---------------End: proguard configuration for Gson ----------
## ------------- Serializable -----------------
# Explicitly preserve all serialization members. The Serializable interface
# is only a marker interface, so it wouldn't save them.
