推荐答案

看起来是和厂商有关。除了使用书中所描述的方法，似乎也允许用户选择/覆盖默认你发现的用户将是一个重要的选择。

Looks like it is manufacturer dependent. In addition to using methods described in book, it seems also allowing the user to choose/override the default you "discover" would be an important option.

不幸的是，没有一个方法调用来告诉你哪些目录可能使用的 DCIM 目录下的摄像头   图片。有几个方法虽然能告诉你在哪里了   SD卡的顶部是。第一个是    Environment.getExternalStorageDirectory（）并返回文件对象   用于SD卡的顶层目录

Unfortunately, there is not a method call to tell you which directory might be used underneath the DCIM directory for Camera pictures. There are a couple of methods though to tell you where the top of the SD card is. The first is Environment.getExternalStorageDirectory() and it returns a File object for the top-level directory for the SD card.
