我正在为我的项目使用几个库，我使用build.gradle添加依赖项，例如Volley和Caligraphy。我试图运行应用程序并且项目构建得很好，但是当应用程序试图访问其中一个外部库时，我得到了这个错误：

我已经尝试清理项目并使Invalidate Cache＆amp;在Android Studio上重新启动，但我仍然遇到错误。可能导致此错误的原因是什么？这是我的build.gradle：

编辑：我已尝试从我的项目中删除书法库，但现在应用程序在我尝试访问凌空库时会出错。

Edit2：启用Instant Run解决了问题，但我不想使用Instant Run，因为它导致应用程序在首次安装时需要很长时间才能加载。为什么即时运行会导致NoClassDefFoundError？有没有办法在不打开Instant Run的情况下防止错误？

2 个答案:

答案 0 :(得分：1)

你可以尝试将构建工具例如.24，gradle plugin，lib，android studio更新到最新版本，并尝试重建项目。

答案 1 :(得分：0)

如果您使用的是Android Studio 2.0，请关闭即时运行，检查multidex 1.0.1是否正在使用并检查您是否正在调用MultiDex.init（）在Calligraphy配置之前。希望它能解决这个问题。
