java - MultiDex 停止运行 Android

Question

昨晚我正在开发我的应用程序，最初我已经达到了 64k 限制，所以现在已经使用了 multidex 一段时间，有时它确实会失败并给我一个 ClassNotFoundException 但我所做的就是重新编译我的代码并且它可以工作，如果失败我重新启动我的计算机，但这次情况不同，MultiDex 似乎排除了我的一个类，这很有趣，因为它一直在工作直到突然停止，它正在做的是排除我的 EnhancedGallery .class 用作我的启动 Activity ，如果我更改为 list 中的某些其他 Activity 作为启动 Activity ，应用程序将一直工作，直到我尝试运行 EnhancedGallery 下面是我的 Gradle 配置

Answer 1

这很辛苦，我终于修复了它，或者我应该说找到了绕过它的方法，因为其他类正在工作，我刚刚创建了另一个类并将所有代码行复制粘贴到新类中并且它起作用了，我还不知道 MultiDex 和我的EnhancedGallery 类之间的附件。
