Android 项目代码混淆

实现Android项目代码混淆三步走战略：一、修改工程下的project.properties文件如下：# This file is automatically generated by Android Tools.
# Do not modify this file -- YOUR CHANGES WILL BE ERASED！
#
# This file must be checked in Version Control Systems.
#
# To customize properties used by the Ant build system edit
# "ant.properties", and override values to adapt the script to your
# project structure.
#
# To enable ProGuard to shrink and obfuscate your code, uncomment this （available properties: sdk.dir, user.home）:
#proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt# Project target.
target=android-10
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt其中最后一行为自行添加的混淆脚本路径，具体脚本编写在 proguard-project.txt 脚本文件内进行。二、修改脚本文件为什么说事修改呢？很简单因为Google已经替我们完成了大部分功能，只需按自己需要增加规则就OK，我得 proguard-project.txt 文件如下：# This is a configuration file for ProGuard.
# http://proguard.sourceforge.net/index.html#manual/usage.html-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-verbose
# ignorewarnings
-ignorewarnings# Optimization is turned off by default. Dex does not like code run
# through the ProGuard optimize and preverify steps （and performs some
# of these optimizations on its own）.
-dontoptimize
-dontpreverify
# Note that if you want to enable optimization, you cannot just
# include optimization flags in your own project configuration file;
# instead you will need to point to the
# "proguard-android-optimize.txt" file instead of this one from your
# project.properties file.-keepattributes *Annotation*
-keep public class com.google.vending.licensing.ILicensingService
-keep public class com.android.vending.licensing.ILicensingService# For native methods, see http://proguard.sourceforge.net/manual/examples.html#native
-keepclasseswithmembernames class * {

}# We want to keep methods in Activity that could be used in the XML attribute onClick
