Question

我收到了这个奇怪的错误。当我昨天晚上回来工作时，我遇到了这个错误。我不明白的是我从未改变过代码中的任何内容。感觉就像它出现了。

注意：我确实搜索了同样问题的其他问题，但我找到了一些问题。但是，我遵循了这些帖子的每一条建议，但对我没有帮助。在浪费了我的整个晚上后，我认为在这里发帖是个好主意。

我不确定我的代码的哪些部分，如果有的话，我应该发布这个，所以我会积极地看看这个，并在必要时进行编辑。

这是清单文件：

谢谢。

Answer 1

我刚才遇到了同样的问题。我从设备上卸载了应用程序，重新构建了项目，然后再次安装。这次我没有遇到问题，而且工作正常。

这可能是工作室中即时播放功能的一些间歇性错误。

Android：ClassNotFoundException
