安卓：如果找到SD卡为present [英] android: finding if sd-card is present

问题描述

我有一个问题。我有一个带有内置16GB的存储和2 GB的SD卡卡的Galaxy Tab的。

I am having a problem. I have a galaxy tab that comes with 16gb of internal storage and 2 gb of sd-card card.

当我用environment.getExternalStorageState，它返回安装。然而，当我从我的Galaxy Tab取出SD卡，它仍返回安装，因为它认为内部存储为外部存储。有没有什么办法的，我可以实际的SD卡和内部存储？区分

when I use environment.getExternalStorageState, it returns mounted. However, when I remove the sd-card from my galaxy tab, it still returns mounted because it considers the internal storage as the external storage. Is there any way in which I can differentiate between the actual SD-Card and the Internal Storage?

感谢

推荐答案

似乎没有成为这个目前任何公开的API。你可以通过查看检查/ proc /坐骑但随后你的code将设备无关，因为不是所有的设备在安装二次外部存储（SD卡）一样的地方。

There doesn't seem to be any public API for this currently. You could check by looking at /proc/mounts but your code would then be device-dependent, since not all devices mount secondary external storage (SD card) at the same place.
