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.

Answer 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.

Answer 2

It's also possible to get this error if you are running the test project using JUnit instead of Android JUnit. Naturally, the solution is just to change how you run it.

Answer 3

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

[2011-12-19 11:45:09 - RayhReport] You must restart adb and Eclipse.
[2011-12-19 11:45:09 - RayhReport] Please ensure that adb is correctly located at 'D:\android-sdk-windows\tools\adb.exe' and can be executed.

When you go to D:\android-sdk-windows\tools\adb.exe path then you see the text file,the name of file is "adb_has_moved" thats means your adb.exe is moved to platform-tools copied down the adb.exe and paste in tools folder and run it. I'm sure it works.

Answer 4

Judging from what you've posted, and assuming it's not a typo, Eclipse is looking in C:\s\platform-tools...

If that's the case, then you should check Eclipse's Window/Preferences/Android option for the SDK Location. Maybe yours is set to "C:\s". You can't edit it to be a value such as that without causing an error, but maybe it's got corrupted somehow.

Answer 5

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...
