Can't Run App On My Phone For Testing: Adb Connection Error:an Existing Connection Was Forcibly Closed By The Remote Host

I am trying to run an app that I made on my phone to test, but my device does not come up in the Devices tab in DDMS. Below is the error I get when I 'Reset adb' in DDMS for androi

Solution 1:

Found the solution to my own problem after much troubleshooting.

Just go to Device Manager and under the Action tab, click on Update Driver Software and it will automatically fix the problem for you by adding "Android USB Devices" to your Device Manager.

Solution 2:

Hopefully this will work with you, I had same problem with my HTC ONE in windows 8 so what I did is that I download the HTC drivers for windows 8, now the same driver works for windows 7 so follow this link it has detailed steps on how to do it. please give me a feedback whether it worked or not.

Solution 3:

I've had problems with HTC devices not being recognized by DDMS. 90% of the time i solved it by installing HTC software (i think it was HTC sync, but im not sure).

Also, make sure you installed USB debug tools from Android SDK manager.

Solution 4:

Don't forget to consider Hardware failure!

Adb connection Error: An existing connection was forcibly closed by the remote host

Facing the same problem I found out the USB cable I was using was slightly damaged, enough to cause constant connection failure. I didn't have problems accessing data on the phone, so it took me a while to find it out.

I replaced the cable and it works fine now!
