您应该阅读 Android Studio 2.0 更改文档。
因为在 Android Studio 中添加了一些新功能及其对其他一些功能的影响。
所以,阅读文档和问题页面,你可以解决这个问题。
根据我的看法,当您的应用 运行 在 Android Studio 的 Instant 运行 功能中发现此类错误时。因此,并非每次都生成新版本,并且在您的 android 设备中找不到应用程序内容。
解决方案在this link或以下指令中定义:

如果上述解决方案无效,请转至 project > app 文件夹 > build 文件夹并在 运行 之后再次删除构建文件夹。
退出 Android Studio,删除构建文件夹,再次打开您的项目。应该可以解决问题。
转到项目并从项目中删除.idea,.gradle & build 文件夹,然后导入项目
