android 导出apk

一个困扰了几个月的问题在今天得以解决，运动益智可能有点过，能让一个人思路清晰倒是真！

问题描述：本地调试运行及不加密导出apk运行正常，当加密生成apk安装后，从接口返回的数据总是空。尝试过各种配置，不加密网络流，不加密调接口的方法.与网络交互的方法类通通通通通通不加密...失败！

信了你的邪，今天把服务器返回的数据Toast出来一看，返回的数据并非空值，原来问题出现在反序列化！

导出加密包用到fastjson反序列化一定要加上

-keep class com.alibaba.fastjson.** { *; }

#-keepnames class * implements java.io.Serializable
-keep public class * implements java.io.Serializable {
        public *;
}

 

step1.将project.properties的proguard.config属性的路径设为proguard-project.txt

# This file is automatically generated by Android Tools.
# Do not modify this file -- YOUR CHANGES WILL BE ERASED!
#
# This file must be checked in Version Control Systems.
#
# To customize properties used by the Ant build system edit
# "ant.properties", and override values to adapt the script to your
# project structure.
#
# To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home):
#proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
# Project target.
proguard.config=proguard-project.txt
target=android-19

step2.修改proguard-project.txt
