Android APK 文件里面有什么
来自网络开发背景，所有文件都单独上传到服务器，APK 文件对我来说非常不同！
据我所知，它有点像 zip 或 exe 文件，类似于您在计算机上安装的软件，例如 Eclipse 本身。然后，当安装在设备上时，文件和文件夹将被提取回类似于我在 eclipse 中处理的文件/文件夹结构。在这种情况下，一旦安装了 APK，我就可以再次访问 /res 和 /assets 文件夹？
我走在正确的轨道上吗？
Coming form a web development background where all your files are uploaded to a server individually, the APK file is very different to me!
From what I gather it’s kind of like a zip or exe file similar to software you install on a computer, e.g. Eclipse its self. Then when installed on a device the files and folders are extracted back into something similar to the file/folder structure I was working on in eclipse. And in which case I then again have access somehow to say the /res and /assets folders once the APK is installed?
Am I on the right track?
