Android极光推送jPush混淆解决方案终极篇

今天在做混淆时，极光推送报错了，错误如下：(下面错误代码从别的文章摘录而来，因为已经解决，就不再显示我自己的错误信息了，基本是一致的，除了时间。)

下面简单把解决方案说一下吧：

1.在你的proguard.cfg加上代码：如果是使用新版本的ADT 将project.properties的中“# proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt”的“#”注释去掉，然后在proguard-android.txt中配置如下：

-dontwarn cn.jpush.**
-keep class cn.jpush.** { *; }

2.使用 SDK1.3.X 及以后的版本

   3.替换D:\adt-bundle-windows-x86-20130729\sdk\tools中的proguard文件夹    点我立即下载最新版混淆文件

如此，便完美解决jPush混淆报错问题了。
