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 toSystem.getenv("EXTERNAL_STORAGE"). EDIT: Found the solution: adb shell echo $EXTERNAL_STORAGE
