在运行时获取ClassNotFoundException，无法在dexpathlist中查找活动

Question

这是我尝试的一系列事项：

1. 已禁用即时运行（之前已禁用，因为我不使用它）
2. 清理并重建了我的项目
3. 项目的检查名称到处都是一样的
4. multiDexEnabled设置为true
5. Followed all steps shown in this link
6. 使缓存无效并重新启动
7. 创建了一个新项目并复制了以前项目中的代码

在Manifest中添加MultiDexApplication行之前，我得到了以下stacktrace：

添加该行后，我得到了这个：

Answer 1

用这个

compileSdkVersion "26.0.0"
buildToolsVersion "26.0.0"

而不是这个

compileSdkVersion 25
buildToolsVersion "26.0.0"
