1.在project.properties文件加入：proguard.config=proguard.cfg，讓項目啓用混淆機制
2.配置proguard.cfg文件：
# -------------------------------------
# android 原始混淆模板

# 通過指定數量的優化能執行
# -optimizationpasses n
# ----------------------------------
-optimizationpasses 5

# 混淆時不會產生形形色色的類名
# -dontusemixedcaseclassnames
# ----------------------------------
#-dontusemixedcaseclassnames

# 指定不去忽略非公共的庫類
