android代码混淆之不同ADT版本和不同IDE之间混淆配置文件的区别

由于adt的更新和IDE的变化代码混淆的配置文件也发生了变化，下面给大家说一下主要发生了什么变化。希望能帮到大家

Eclipse中老版本的ADT里面是proguard.cfg，然后在defult.properties加入proguard.config=proguard.cfg。defult.properties文件是这样的

[html] view
plaincopy

# 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 use,

# "build.properties", and override values to adapt the script to your

# project structure.

# Project target.

target=android-19

proguard.config=proguard.cfg

新版ADT没有了proguard.cfg而是换成了project.properties和proguard-project.txt。其实没啥区别在project.properties加入proguard.config=proguard-project.txt。就可以了。proguard-project.txt文件是这样的。

这里要知道一个地方proguard.cfg是可以直接拿过来当proguard-project.txt用的。

[html] view
plaincopy

# 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-19

proguard.config=proguard-project.txt

新版ADT没下面说一下android studio的使用，到了android studio中又有了不同这回没有了proguard-project.txt变成了proguard-rules.txt其实就是名字变了而已。用法一样。不同的是studio中没有了eclipse里面的project.properties或者defult.properties。而是换成了build.gradle。build.gradle中有这么一段。只要把minifyEnabled
后面的false改为true就会执行混淆代码了。

[html] view
plaincopy

buildTypes {

release {

// minifyEnabled为true会执行proguard-rules.txt混淆代码

minifyEnabled false

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'

}

}

到此配置文件的不同就介绍完毕了
