Error “The connection to adb is down, and a severe

Question

I've spent days trying to launch any Android program. Even "Hello World" gives me the same error:

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

I'm running Eclipse v3.5 (Galileo), Google APIs 2.2.8, on a Windows XP machine.

I've used all the tricks I can find on the web: the command line "adb kill-server", the DDMS "reset ADB", I started the emulator both before and after Eclipse, and searched for ports being used by other programs.

What is going on here? Is there a magic combination of versions of Eclipse, Java, ADB, emulator, and whatever else that works?

Answer 1

I've tried the above methods, end the adb process through task manager and all, it didn't work. But when I ran the adb.exe file as admin it worked fine.

Answer 2

1. Go to the folder platform-tools in cmd folder platform tools available in the Android folder where you have Android backup files.

2. Type the following

   adb kill-server
   

   and

   adb start-server
   

   then type

   adb devices
   
   adb kill-server
   

You can now see your device.

Answer 3

Eclipse → preferences → Android → NDK

Check the "NDK Location" path is set correctly, and use the browse button to set it.

Answer 4

Close Eclipse

Use this in the terminal:

sudo killall -9 adb

Run Eclipse.

Answer 5

AndroidSDK → Platform Tools → Kill did not work.

But after restarting my computer, it worked.

Answer 6

Open up the Windows task manager, kill the process named adb.exe, and re-launch your program.
