代码混淆

-optimizationpasses 5 #指定代码的压缩级别 0 - 7 
-dontusemixedcaseclassnames #是否使用大小写混合 
-dontskipnonpubliclibraryclasses #如果应用程序引入的有jar包，并且想混淆jar包里面的class 
-dontpreverify #混淆时是否做预校验（可去掉加快混淆速度）
-verbose #混淆时是否记录日志（混淆后生产映射文件 map 类名 -> 转化后类名的映射 
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*  #淆采用的算法
