Conversion to Dalvik format failed with error 1

Sometime You will encounter this problem when trying to Build Android Project on Eclipse..
 You will get such output in console:



[2011-05-24 09:25:03 - Android C2DM] Dx 1 error; aborting
[2011-05-24 09:25:03 - Android C2DM] Conversion to Dalvik format failed with error 1


You can solve this problem:


Go to Project » Properties » Java Build Path » Libraries and remove all except the "Android X.Y" (in my case Android 2.2). click OK. 
and then
Go to Project » Clean » Clean projects selected below » select your project and click OK.


 That work for me. Hope it works for you too.!!!!
