One possible reason for the occurrence of this error is due to the difference in adb versions in the development machine and the connected connected device/emulator being used for debugging.

So resolution is:

Firstly disconnect device/emulator.
Run on terminal/command prompt following commands:
```
adb kill-server
adb start-server
```

This will start the adb successfully. Now you can connect device. Hope it helps.

For me it was happening because I had android tools installed in two places  1  The location where I manually downloaded it from google 2  Automatic download by Android studio    What I was able to do was completely delete the folder in  1 and point my bash profile and all other references to the location where Android studio installed it for me   Users my user name Library Android sdk  This solved it

For anyone still having this issue   on windows      Open task manager Go to processes and select the ADB EXE Right-click on it and check the properties Most likely you will see a different path from where the adb exe is running   either HTC manager  Genymotion  etc   Kill the process Run ADB exe from your android studio path   in my case  C  Users  user  AppData Local Android sdk platform-tools     This solved the problem in my case

It seems there are 2 adb version in your system  Please find them out and keep the adb in your Android SDK folder only  delete all others folders that including adb file  You can find out which adb you are using from Application Monitor     It might be a problem if the adb is not the one in you Android SDK folder   In my case  I found I was running adb from here        Library Application Support RSupport Mobizen2   after deleting the Mobizen2 folder  then all adb commands work fine

Most likely you have several adb version on your computer  You start adb server using one version and then trying to connect to this server using another version  For example - Genymotion has it s own adb and if you start Genymotion emulator and then try to use adb from Android SDK most likely you will have such error  the latest Genymotion which is 2 7 2 has adb version 1 0 32 while the latest Android SDK has adb version 1 0 36
