Android Studio 打包时混淆出错

2016-11-9 遇到的一点小问题
今天要打包结果发现提示以下错误:
app:transformClassesAndResourcesWithProguardForCeshiRelease

混淆打包失败

具体内容如下,基本一样:

就是提示混淆时出错,到混淆文件查找,有这句话
-keep class sun.misc. { ; }*
按网上说的把这个删掉,还是出错.后来又试了下,才发现应该是添加全.
再加上这个** -dontwarn sun.misc.****
两个都写上就没问题了,记录一下

然后是接拉卡拉的SDK第一次发现原来so文件还可以打成jar包来放,如图：

拉卡拉so文件

jar包日期竟然20150424，，，好久啊。
顺便吐槽一下拉卡拉的sdk真的是太不友好了，一堆drawable，colors,layout,string...
啥都有就是了,还都得放进去；功能太杂，全部堆到一个jar包里面，十几个功能，然而我们只需要用一两个；sdk的返回值也做得一般，虽然有四个返回类型，但成功方法竟然要进入两次才代表付款成功；然后就是测试环境和生成环境的jar竟然是不一样的，命名啥的都一样，但就是用不了，直接回调参数错误，也不说具体原因，为这问题找半天；还有就是demo版本用的API17，用的方法有些现在过时了。。。

不过学到个好东西，之前竟然一直没注意。之前解析json一直都是getString()但这方法如果没参数会抛出异常,用optString()则不会，还能自定义没有对应key时的返回值。
