android studio 1.0 代码混淆

                

         

        google在14年底发布了首款AndroidStudio1.0正式版，我们终

于可以摆脱Eclipse的卡顿，进而体验Studio的快感，之前有用过

Studio的朋友都应该知道，之前的Studio用起来还是不是很爽，但

是1.0正式版解决了之前版本的不足，很容易上手。相比Eclipse的

代码混淆，android Studio 的代码混淆太爽了，几乎没有太多需要

我们去写的混淆配置文件，我们先来看一下Eclipse的混淆文件

 # To enable ProGuard in your project, edit project.properties
 # to define the proguard.config property as described in that file.
 #
 # Add project specific ProGuard rules here.
 # By default, the flags in this file are appended to flags specified
 # in ${sdk.dir}/tools/proguard/proguard-android.txt
 # You can edit the include path and order by changing the ProGuard
 # include property in project.properties.
 #
 # For more details, see
 #   http://developer.android.com/guide/developing/tools/proguard.html

 # Add any project specific keep options here:

 # If your project uses WebView with JS, uncomment the following
 # and specify the fully qualified class name to the JavaScript interface
 # class:
 #-keepclassmembers class fqcn.of.javascript.interface.for.webview {
 #   public *;
 #}

这把人逼的什么都给他排除 ，是不是感觉大门敞开呢，很没有安

全感？我们再来看下Studio 的混淆

第1步，我们将模式改为打包发布模式 点击build Variants(在studio的左下角方向)

</pre><h1 style="margin: 0px; padding: 0px;"><a target=_blank name="t3" style="color: rgb(202, 0, 0);"></a><span style="color: rgb(255, 0, 0);"></span></h1><h1 style="margin: 0px; padding: 0px;"><a target=_blank name="t4" style="color: rgb(202, 0, 0);"></a><span style="color: rgb(255, 0, 0);">第2步 修改模式 修改为 release</span></h1><div><span style="color: rgb(255, 0, 0);"></span></div><p style="margin-top: 0px; margin-bottom: 0px; padding-top: 0px; padding-bottom: 0px;"><img src="http://img.blog.csdn.net/20150116093332921?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvdTAxMDIwNTY2Mg==/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="<img src="http://img.blog.csdn.net/20150116093332921?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvdTAxMDIwNTY2Mg==/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="<img src="http://img.blog.csdn.net/20150116093332921?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvdTAxMDIwNTY2Mg==/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="" />" />" style="border: none; max-width: 100%;" />             <img src="http://img.blog.csdn.net/20150116093444844?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvdTAxMDIwNTY2Mg==/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="

" />" />

" style="border: none; max-width: 100%;" />
第3步 检查那个jar包需要进行混淆排除，我们来看一下libs里面的jar ,展开jar，我们
明显可以看出已经混淆了的jar，然后进行混淆排除，其他的就不要管了直接默认混
淆
    
    
    
    

     
     
     
     
    
    
    
    
第4步 我们来到studio的混淆文件里面进行混淆相应的排除，打开此文件进行配置
    
    
    
    

     
     
     
     
    
    
    
    
    
    
    
    

打开之后可以看到和Eclipse的非常相似，不过这次我们只需要排除不需要混淆的，我的项目是需要排除友盟的SDK,如下图
    
    
    
    

     
     
     
     

    
    
    
    

是的，就只需要这样就可以了，是不是很简单呢，不过我的项目里面使用了fastjson 所有的常量类都需要排除，由于我的常量类都实现了序列化所以我需要这样给排除一下
    
    
    
    

     
     
     
     

    
    
    
    

如果有需要可以配置以下参数
    
    
    
    

     
     
     
     

    
    
    
    


第5步 好了这次大工告成，配置的混淆文件OK了，接下来就可以开启混淆配置的属性
    
    
    
    

     
     
     
     

    
    
    
    

最后，我们需要签名模式打包，设置签名点击下一步就Ok了
