Please link your libs the correct way, your libraries are not compiled with your app, if you are using 3rd party libraries make sure you are copying them to the project when linking them. A screenshot of your linked libraries would help more.
请以正确的方式链接您的库，您的库未与您的应用程序一起编译，如果您使用的是 3rd 方库，请确保在链接它们时将它们复制到项目中。链接库的屏幕截图会更有帮助。
Also on a side note, try to move to Android Studio its much better than Eclipse in handling libraries.
另外顺便提一下，尝试转向 Android Studio，它在处理库方面比 Eclipse 好得多。

it is saying -
它在说——
java.lang.ClassNotFoundException: Didn't find class "com.versus.hit.yeni.ACProgressFlower$Builder"
check what you are calling is it exist in bin folder on the same path or not if not try to add again same library as @ahmad saidor clean the project and run again.
NoClassDefFoundErrorindicates that the Class Loader cannot find the .class file for the class that you're trying to use.
如果不尝试再次添加与@ahmad said项目相同的库或清理项目并再次运行，请检查您正在调用的内容是否存在于相同路径的 bin 文件夹中。
NoClassDefFoundError表示类加载器找不到您尝试使用的类的 .class 文件。

I solved mine by changing
我通过改变解决了我的

Remove temporary .gradlefolder from your Project folder.

In my case it happens because I move the project location. I remove the ".gradle " package of main module, then solve the problem.
就我而言，这是因为我移动了项目位置。我删除了主模块的“.gradle”包，然后解决了问题。

If you don't do anything on your project, but catch this issue, this you can try. Android is new to me, so when I get this issue I clear all files which auto generated include .gradle, .buildand etc by android studio. It works! enjoy your coding!
如果你没有对你的项目做任何事情，但是发现了这个问题，你可以试试这个。Android是新的给我，所以当我得到这个问题，我清楚其中自动生成的包含的所有文件.gradle，.build并等由Android工作室。有用！享受你的编码！

It looks like you have minifyEnabled truein your gradle file in release buildTypes and minifyEnabled falsein debug.
看起来您minifyEnabled true在发布 buildTypes 和minifyEnabled false调试中的 gradle 文件中都有。
If so, try to add in your proguard-rules.profile:
如果是这样，请尝试在您的proguard-rules.pro文件中添加：
-keep class com.versus.hit.yeni.ACProgressFlower$Builder-keep class com.versus.hit.yeni.JSONParser
-keep class com.versus.hit.yeni.ACProgressFlower$Builder-keep class com.versus.hit.yeni.JSONParser
