I had this problem on my ubuntu. I just ran adb from sdk/platform-tools instead of pre-installed version on my system and it worked fine.

This answer may help some. The adb.exe has problems with virtual devices when you are using your phone for tethering. If you turn off tethering it will correct the problem.

Answer 4

So I was getting this problem and found that a process called dcb was running an older version of adb. So I renamed the folder /usr/local/var/dcb to /usr/local/var/OLDdcb and it was recreated automatically and I was able to successfully run my tests in the emulator.

Answer 5

Check your firewall and antivirus for permissions for Android Debugger Bridge (adb.exe).

Answer 6

I've finally solved a very similar issue!

In my case, the problem was that I had two different SDKs (one from Eclipse and the other from Android Studio), so I was trying to execute the ADB commands in the wrong one.

So it is important that you check the path you are using in your IDE and execute the commands on the same.
