如何启用ProGuard的混淆Android Studio中？ [英] How to Enabling ProGuard obfuscation in Android Studio?

问题描述

我必须让Proguard的混淆Android Studio中，以保护我的应用程序。我已经寻找如何应用它的进程，但我没有得到任何明确的解决方案。当我尝试它，我总是得到一个错误。因此，谁能告诉我明确的步骤，在我的应用程序应用它？

我通过以下步骤执行此操作：

1. 在Android Studio中，打开一个Android项目。




2. 切换到项目视图。




3. 更​​改以下行：

   minifyEnable假到 minifyEnable真正




4. 设置ProGuard的规则（可选）

   4.1项目视图，选择proguard-rules.pro文件。

   4.2中添加以下行来告诉ProGuard的不要混淆某些类。

     -keepclassmembers类com.dom925.xxxx
   {
     上市 *
   }
    

错误，我按照获取步骤搜索

  

错误：执行失败的任务：应用程序：packageRelease。
  无法计算的D散列：\\ Android的\\ Pojectname \\程序\\编译\\中间体\\班，proguard的\\发布\\ classes.jar

解决方案

我想通了这个问题：

开拓proguard-rules.pro为您的项目，将其添加到底部：

  -dontwarn java.nio.file.Files
-dontwarn java.nio.file.Path
-dontwarn java.nio.file.OpenOption
-dontwarn组织。codehaus.mojo.animal_sniffer.IgnoreJRERequirement
 

我基本上是怎么解决的，这是我试图运行我的'释放'模式的应用程序，并得到了一堆类似这样的家伙在这里的错误：的 https://github.com/square/okio/issues/144

我pretty多跟着他所说的和固定的。

希望这可以帮助别人产生自己的APK的！

I have to protect my app by enabling Proguard obfuscation in Android Studio. I have searched for the process of how to apply it but i did not get any clear solution. When i try it, i always get an error. So can anyone tell me the clear steps to apply it in my app?

I am doing this by the following steps:

1. In Android Studio, open up an Android project.

2. Change to Project View.

3. Change the following line:

   minifyEnable false to minifyEnable true

4. Set ProGuard Rules(optional)

   4.1 In Project View, select the proguard-rules.pro file.

   4.2 Add in the following lines to tell ProGuard not to obfuscate certain classes.

   -keepclassmembers class com.dom925.xxxx 
   {
     public *
   }
   

Error that I am getting by following the steps are

Error:Execution failed for task ':app:packageRelease'. Unable to compute hash of D:\Android\Pojectname\app\build\intermediates\classes-proguard\release\classes.jar

解决方案

I figured out the problem:

Open up the proguard-rules.pro for your project and add this to the bottom:

-dontwarn java.nio.file.Files
-dontwarn java.nio.file.Path
-dontwarn java.nio.file.OpenOption
-dontwarn org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement

Basically how I solved it was this I tried to run my app in 'release' mode and got a bunch of errors similar to this guy here: https://github.com/square/okio/issues/144

I pretty much followed what he said and fixed it.

Hope this can help others with generating their APK's!
