Android--混淆

-optimizationpasses 5                                                    # 指定代码的压缩级别 默认为5

-dontusemixedcaseclassnames                                              # 是否使用大小写混合 （即小写）

-dontskipnonpubliclibraryclasses                                         # 是否混淆第三方jar (否)

-dontpreverify                                                           # 混淆时是否做预校验 (否)

-verbose                                                                 # 混淆时是否记录日志

-optimizations !code/simplification/arithmetic,!field/*,!class/merging/* # 混淆时所采用的算法(谷歌)

-keepattributes *Annotation*                                             #假如项目中有用到注解 应用加入

-keepattributes Signature 

#声明第三方包

# 保持 native 方法不被混淆  

-keepclasseswithmembernames class * {

}

# 保持自定义控件类不被混淆

-keepclasseswithmembernames class * {

-keepclassmembers class * extends android.content.Context {

#保留View子类读取XML的构造方法：

    #保持R文件

-keep public class cn.com.lmbj.car.R$*{

#去除调试日志，将所有Log.d()改为Log.i():

-assumenosideeffects class android.util.Log{

  public static *** d(...);

  public static *** i(...);

  public static *** e(...);

}

最后在project.properties里面加上proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
