Get sdcard directory by adb

解决方案： adb shell echo $EXTERNAL_STORAGE 

I am making an application, which pulls files(Saved by android app) from the device sdcard by adb. The problem is that different devices, have various sdcard directories

i.e:

• sdcard
• sdcard/external_sd

Firstly I invented following solution:

1. run adb shell
2. ls
3. Check if dir "sdcard" exists
4. If yes run sdcard/ ls and check if external_sd exists
5. return value.

But the problem is that I have two samsung devices GT-I9100 and GT-I9000 and both have a directory sdcard/external_sd. When I am checking System.getenv("EXTERNAL_STORAGE") one returns sdcard and another sdcard/external_sd. I need to pull file which was previously saved toSystem.getenv("EXTERNAL_STORAGE").

EDIT: Found the solution:

adb shell echo $EXTERNAL_STORAGE
