Android Studio + Volley = NoClassDefFound? [英] Android Studio + Volley = NoClassDefFound?

问题描述

好吧，我决定同时试用适用于Android的Volley网络库和新的Android Studio IDE.但是，我遇到了一些问题.

Well, I decided to try out the Volley networking library for Android and the new Android Studio IDE at the same time.. However, I'm running into some problems.

我构建了volley.jar，将其复制到新项目的libs文件夹中，编辑build.gradle以包括volley，并在我的主要活动中设置了静态ImageLoader和RequestQueue.但是，当我将应用程序加载到仿真器(4.2)上时，最终得到

I built volley.jar, copied it into my libs folder for a new project, edited build.gradle to include volley, and setup a static ImageLoader and RequestQueue in my main activity. However, when I load the app onto an emulator (4.2), I end up getting

E/AndroidRuntime: FATAL EXCEPTION: main
        java.lang.NoClassDefFoundError: com.android.volley.toolbox.Volley

当调用Volley时，如下所示:

when invoking Volley as follows:

        queue = Volley.newRequestQueue(this);

进行分级编辑以支持该库:

Gradle edits to support the library:

dependencies {
    compile files('libs/android-support-v4.jar')
    compile files('libs/volley.jar')
}

有人介意向我指出正确的方向吗?

Anyone mind pointing me in the right direction?

推荐答案

在此处找到修复程序.

基本上，打开命令提示符(或终端)并导航到您的项目目录.在Windows上使用以下命令:

Basically, open a command prompt (or terminal) and navigate to your project directory. Use the following command on Windows:

对于 Windows 用户: gradlew.bat clean

For Windows users: gradlew.bat clean

对于 mac 用户，键入:./gradlew clean

And for mac users type: ./gradlew clean

然后重新加载Android Studio，然后重试！

Then reload Android Studio and try again!
