ADB error: cannot connect to daemon

Question

I need help to get ADB working on my PC (win7 64bit) with the Samsung Galaxy S2.

I have installed the drivers coming along Kies, I think under sub folder \"25_escape

Answer 1

Same issue for me. Was stumped. After I removed "Dell PC Suite" the problem went away.

Answer 2

Go to windows task manager and end process tree of adb. It will make attempts to start adb.

Sometimes on Windows adb kill-server and adb start-server fail to start adb.

Answer 3

If nothing works Restart your PC . Restarting my computer does the trick

Answer 4

I had a couple of things open that prevented ADB from properly running. Specifically, I had BlueStacks Tweaker (to kill BlueStacks which runs in the background) and another program. Both use their own bundled adb.exe version for issuing commands. I was then also using my system's adb.exe. I had to close the other two programs in order to solve the problem. Restarting my computer would've also solved the problem (by closing those programs for me lol).

Answer 5

If the above methods did not work, (such as restarting, killing, rebooting, reconfigure, updating, permissions .. etc) the bug might be in the last opened files tab. I had a file I was accessing from data/data/... and whenever I opened A.S, the panel always showed the error. Just close the tabs and restart AS.

Answer 6

Delete you AVD and create another. Maybe isn't the perfect thing to do, but it's the fastest.
