DDMS – Can't bind to local 8600 for debugger on Android Studio-ThrowExceptions

Exception or error:

Am trying to view my database tables using Android Device Monitor and It showing me Errors for reasons which i am not really sure of. And i don’t have another instance of DDMS running.

Instead of showing my DDMS, Its showing me this errors

[2015-09-10 17:39:53 - ddms] Could not open Selected VM debug port (8700). Make sure you do not have another instance of DDMS or of the eclipse plugin running. If it's being used by something else, choose a new port number in the preferences.

Please, any one knows a solution to this ???

How to solve:

Try killing the adb server and restarting the adb server from terminal.

adb kill-server
adb start-server

Also on your mobile device, toggle the usb debugging.
Both of these combine worked for me when I had this issue.

Also you may want to consider using Stetho by Facebook, you can view your database as well as run queries with Stetho. Stetho also lets you watch network calls, view your view hierarchy and more.


On Mac, Open terminal and type:

    sudo nano /etc/hosts

Add following line to your hosts file        localhost

Save and exit.

In Android Studio, you can start debugging again. I got stuck with the same problem and I ended up doing above, problem solved.

Hope this helps 🙂 .


A similar question helped me solve this issue here:

Android Studio and android device monitor

By opening DDMS from within Android Studio, I am able to bind and monitor my android devices with no more broken pipes or port conflicts.

Simply follow these steps to open DDMS from within android studio:
Select Tools > Android > Android Device Monitor

I can only assume AS runs a DDMS instance silently, since when AS is closed, manually opening DDMS has no issues. Only when AS is running do I get this when running DDMS from the CLI


For osx users

Yes you need to restart adb. Simply restart android studio should do the trick. If it’s still not working, force killing the thread on port 8600 by this

[sudo] lsof -i :8600

Then for the PID

kill -9 <PID>


What worked for me was restarting the computer. I think this happened after force-quitting Android Studio.


in case of converting your webapp into android app.

if u give your url like this : localhost:xxxx/abc/xx
then it create the problem because the port of your localhost and port of your emulator is different. you are using emulator it work like a separate device in your computer.
