Hi. What can I do when it says "error: device offline" after typing in "adb shell"? Thanks.
Hi. Please help. I can't figure out how to do this on my Macbook El Capitan OS. I have already downloaded the Android Studio app for Mac. When I try to enter "adb shell" on my terminal it says "command not found". Have I skipped a step? How do I make my Mac "adb" working. Thank you!
