Android adb “Unable to open sync connection!”

Question

I can run and debug my Android app on my phone just fine, most of the time. Then, seemingly randomly, when I try to run or debug my app from Eclipse, the Console in Eclipse

Answer 1

I see this problem regularly in both attached devices (Phone or Tablet) and even the emulators. I noticed that the problem often follows periods of inactivity (after a lunch break for example). It may be that the Operating System on the development machine is trying to conserve resources and adb just isn't all that JIT friendly. On windows I have to close the IDE and open Task Manager and force stop (kill) adb, then relaunch Eclipse. This always works for me...

• I noticed if I set a higher priority in task manager for adb, this problem is greatly reduced--although it can still happen.
