The connection to adb is down, and a severe error has occured

I am currently trying to develop an application for Android in the latest release of Eclipse. When I try to build and run, the following comes up:

[2011-02-17 17:08:03 - <ProgramName>] The connection to adb is down, and a severe error has occured.
[2011-02-17 17:08:03 - <ProgramName>] You must restart adb and Eclipse.
[2011-02-17 17:08:03 - <ProgramName>] Please ensure that adb is correctly located at 'C:\<sdk-directory>s\platform-tools\adb.exe' and can be executed.

Now, I have updated the ADT plugin, I have the latest version of the Android SDK; adb.exe is, in fact, in the platform-tools directory and can be executed. I've tried everything I found on Google:

• I tried adb kill-server and adb start-server
• I tried to run it with an without an emulator started
• I have the given directory in my PATH (I tried with just the platform-tools in the path and I tried with having both platform-tools and tools in my PATH).

Notes: I am running Windows 7. Also, I have previously tested apps in Eclipse. This error is new to me since upgrading the SDK.

Solution 1

I just got the same problem and to fix it, I opened the task manager and killed the adb.exe process, then I restarted Eclipse.

Solution 2

Reinstall everything??? no way! just add the path to SDK tools and platform tools in your classpath from Environment Variables. Then restart Eclipse.

other way go to Devices -> Reset adb, or simply open the task manager and kill the adb.exe process.

Solution 3

I restarted eclipse and did the Project -> Clean -> select your project One of them fixed my problem with adb

[2011-12-31 10:50:45 - HelloAndroid] Android Launch!                      good

[2011-12-31 10:50:45 - HelloAndroid] adb is running normally.             good

[2011-12-31 10:50:45 - HelloAndroid] Could not find HelloAndroid.apk!     bad

Thanks for the help. On to the next problem (sigh)

Solution 4

Sounds a bit familiar with my problem: aapt not found under the right path

I needed to clean all open projects to get it working again...

Solution 5

I had exactly the same problem with you. And after two days wondering why this occurs to me, I finally got through this by moving the adb.exe from the unreliable software list of the COMODO anti-virus to its reliable software list. At that time, I had tried at least 5 kinds of measures to make the adb work, including all above...

Okay, so I shut down Eclipse and then ran it as administrator. I uninstalled the ADT, and then re-installed it. Still getting the same problem.

By clean, do you mean right clicking on the project, going to "Source" and clicking "Clean up..."?

The SDK location is pointing to the root of my SDK on my device. I tried to edit it to see if setting it to the platform-tools location would work, but it would not allow me (as I expected). However, the error message stated: "Could not find folder 'tools' inside...[directory]" Is it suppose to say tools? Or something else? Thanks!

no, I mean Project -> Clean -> select your project

@NickT: Eclipse does not have issues finding the android SDK if you point it to the right directory.

Did it without even restarting Eclipse, just unplugged the phone and plugged it back in.

I tried everything until I saw this answer. Just cleaning fixed the problem. I'd give you a hundred upvotes if I could. thanks!

[Hardik Joshi]

its worked for me.. thanks.

For those who can't run, even after restarting and cleaning. go to the /sdk/platform-tool/ via terminal, to make adb tool executable write sudo chmod 777 adb. It`s helped me, good luck.

Thanks for the COMODO tip. What worked for me was from COMODO -> Defence+ -> ViewActiveProcessList right click on adb.exe and emulator-arm.exe and select "Add to Trusted Files". Then kill those processes and restart eclipse.
