我已经花了几个小时试图让库与我的Andr​​oid Studio项目的工作，我只是不明白。

下面就是我的依赖性看起来像我的模块

和我的库：

我还添加

 编译文件（库/路标，commonshttp4-1.2.1.2.jar）
编译文件（库/路标核心 -  1.2.1.2.jar）
 

我build.gradle。没有这一点，应用程序甚至不会编译。

在这个阶段，当我尝试引用code中的图书馆之一，应用程序崩溃与出现NoClassDefFoundError例外。

东西告诉我，这不应该是这样的难 - 我是什么俯瞰

解决方案

我有相同的问题， 和你一样我认为这足以增加

 编译文件（库/路标，commonshttp4-1.2.1.2.jar）
编译文件（库/路标核心 -  1.2.1.2.jar）
 

这所有的工作后，我做了一个 ./ gradlew干净（我在Mac上，所以你的情况，等效）。 你应该从当你位于项目的根目录下的终端/命令提示符下执行此命令。

I've spent hours trying to get a library to work with my project in Android Studio, and I just can't figure it out.

Here's what my dependencies look like for my module

And my libraries:

I've even added

compile files('libs/signpost-commonshttp4-1.2.1.2.jar')
compile files('libs/signpost-core-1.2.1.2.jar')

to my build.gradle. Without this, the app would not even compile.

At this stage, when I try to reference one of the libraries in code, the app crashes with a NoClassDefFoundError exception.

Something tells me this shouldn't be this hard - what am I overlooking?

I had the exact same problem, And like you i thought it's enough to add the

compile files('libs/signpost-commonshttp4-1.2.1.2.jar')
compile files('libs/signpost-core-1.2.1.2.jar')

It all worked after i did a ./gradlew clean (I'm on a mac, so in your case, the equivalent.) You should do this command from the Terminal/Command prompt when you're located on the root of your project.
