Deleting the jar file in work space will do the trick

projectname>libs>android-support-v4

and go to

appcompat_v7>libs>android-support-v4

copy this file and paste it in your project This process will help you bypass all the errors regarding this issue

Worked well with this project :), But I created a new project and it is giving me errors of ActionBarActivity cannot be resolved total of 9 errors , I previously fixed these by adding external jars. I have to do this for every project or there is a solution? – Zain ul abdeen Nov 03 '14 at 11:28

This is a temporary solution for each project i used to copy paste the jar files . Later i updated my ADT and SDK i never faced such kind of problem so far.Updating the ADT and re-installing Sdk's will do the trick. **This is a temporary quick fix** – Krishna Nov 03 '14 at 11:38
Can you please explain what should I do now? – Zain ul abdeen Nov 03 '14 at 11:40
Just update your ADT and install any new tools available in sdk manager. – Krishna Nov 03 '14 at 12:16
Always remember you must be having the sdk tools for that particular version of android for targeting.So dont delete any sdk tools when you update to new one and always check the version you are targeting with your available sdk tools – Krishna Nov 03 '14 at 12:18
Thankyou :) yeap helped alot – Zain ul abdeen Nov 03 '14 at 12:36
