Windows 上的 Android Studio：ADB 没有响应。 如果您想重试，请手动杀死“adb.exe”并单击“重新启动”

Question

I downloaded Android Studio on windows, and I am trying to run the default HelloWorld application. However, when I run that app, I get a dialog box with the following:

ADB not responding. If you'd like to retry, then please manually kill "adb.exe" and click 'Restart'

I've searched for solutions online and most of it was to kill the adb server and start it again manually, but when I do so in the command line I get:

sdk\platform-tools>adb kill-server
* server not running *

sdk\platform-tools>adb start-server
adb server is out of date.  killing...
ADB server didn't ACK
* failed to start daemon *

And the first error keeps showing. I restarted my machine, and the problem is still there. Any ideas? Thanks.

I tried this fix: http://visualgdb.com/adbfix/#adbfix_download but it did not work. It showed: "No Conflicts Found".

Note: I need the app to run on my device. Not on emulator

I was facing same issue in win7 and I took these steps to resolve the problem:

When starting Android Studio, it warns you with ADB not responding . If you'd like to retry, then please manually kill the process. You should enter cmd , and input adb kill-server for ten times or more.

When the building has finished, input adb start-server and you will see

daemon not running. 
starting it now on port 5037 
daemon started successfully
