Android Studio "waiting for debugger"

Question

I've created simple "Hello, world!" project using android studio. When I run it on the device or emulator - everything is fine. Then I make attempt to run it in the debug mode - and it fails after a few minutes "waiting for debugger" dialog on the screen and

`Error running test-test: Unable to open debugger port : java.io.IOException`

message in event log.

How can I solve this problem?

Michael Yunusov this problem was on different machines the same time.

Solution: I had two IDEs running the same time: Android studio and Eclipse. Closing one of them fixed the issue.

Problem was in conflict between ide's (Eclipse and AS). I had to close one of them) — Johnny Doe, May 16 '13 at 14:25

Try to reset your ADB.

To reset the ADB server: Open Run-> Cmd-> adb kill-server

To start it again you can use: Open Run-> Cmd-> adb devices

At least in OSX you need to start the adb service with `adb start-server` before running `adb devices` – hoss Jun 19 '13 at 14:35

It doesn't work for me... The "Waiting for Debugger" message is still there when I run the app. – mxi1 Jan 23 '15 at 07:58

I can't find anything like a "Cmd" item in my "Run" menu on my Android Studio. – hippietrail Sep 14 '19 at 19:11
@hippietrail You can open a terminal window through your OS and run "adb kill-server" and "adb start-server". – Ellen Spertus Feb 12 '20 at 17:47

How it worked for me.

1. Start Android Device Monitor from Tools -> Android -> Android Device Monitor

2. Click on Stop for the process you are facing the issue from list of devices.

If you can post your same answer to multiple questions, the questions are probably duplicate. Flag them as such instead of copying your answer around the site. – rene Mar 26 '17 at 13:44

I don't even have a Tools/Android menu in my Android Studio and Help/Find Action did not find anything similar to Android Device Monitor. – hippietrail Sep 14 '19 at 19:13

Go to Setting > Developer Options > open Revoke USB debugging authorizations >choose OK

If you cannot find Developer Options: go to [Settings] > [About Phone], and tap [Version] for 7 times
