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: run adb shell ls Check if dir "sdcard" exists If yes run sdcard/ ls and check if external_sd exists 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 to System.getenv("EXTERNAL_STORAGE") . EDIT: Found the solution: adb shell echo $EXTERNAL_STORAGE
