Answer 2

I was also facing same problem, but I resolved it I am using android studio 2.3 open command prompt and set the path to platform tools i.e. "C:\Users\\AppData\Local\Android\sdk\platform-tools"

then write adb.exe as shown

C:\Users\sandeep\AppData\Local\Android\sdk\platform-tools>adb.exe

then restart your studio It will working fine.

Answer 3

I was using Avast and found out that the adb.exe was in the virus chest and i simply restored it as an exclusion, now it worked perfectly. Don't keep the Android Studio outdated, Thanks Avast Virus Chest

Couple of updates to this working solution

1) Virus Chest Image

2) Restore adb from the virus chest & also add android-studio folder under exclusions to avoid the issue in future
