Below steps worked for me.

  1. Close the Eclipse if running
  2. Go to the Android SDK platform-tools directory in Command Prompt
  3. Go to Tak manager and kill adb.exe
  4. From command prompt type adb start-server

If No error message is thrown while starting ADB server, then adb is started successfully.

Now you can start Eclipse again. Restart phone.

Along with the above all suggested answer try this one also, it worked for me

copy the hprof-conv.exe from C:\adt\sdk\tools to C:\adt\sdk\platform-tools
and
copy the adb.exe from C:\adt\sdk\tools to C:\adt\sdk\platform-tools

Ok I solved my issue. I go to Task Manager in windows7 -> processes -> selected the adb.exe -> End Process. After that I go to cmd prompt and type adb start-server. This time adb statred succefully. I run eclipe and it was showing no error.

    C:\Program Files (x86)\Android\android-sdk\platform-tools
  • click on adb.exe
