我昨天安装了Android Studio,在与多个java和其他错误作斗争后,我遇到了一个我似乎无法解决的错误.我没有添加任何内容或完成任何代码,我只是刚刚开始一个新项目,我通过电话在预览中收到此错误:
渲染问题:
The following classes could not be instantiated:
- android.support.design.widget.FloatingActionButton
接下来是一堆异常细节.所有的帮助表示赞赏,我变得绝望.另外,请具体说明复杂的答案,因为我对此还不是很了解.
如果需要异常详细信息:

有时当我重新启动我的应用程序进行测试时,我会被抛出致命的侮辱.不会一直发生,我正在通过我的设备测试而不是模拟器,就像我一直这样.我没有看到我的代码出错的行,所以不确定该怎么做？
