Open Android SDK Manager to check the status of Android SDK Build-tools. – coolscitist Jun 18 '13 at 07:29

Thank you. i made a problem on installing Android SDK Build-Tools. Now the problems are solved. – Kalai Jun 18 '13 at 10:55
Ensure the code, resources and AndroidManifest.xml do not have any problem.
First, delete the R.java file. As soon as you delete, that file should be re-generated automatically if you have enabled automatic build (Project->Build Automatically).
If that doesn't work try to clean the project by clicking on Project->Clean.
If it still doesn't work then, confirm you have android sdk build tools installed. For this, open Android SDK Manager and ensure Android SDK Build-tools has the status of Installed.
Also confirm that the ADT is up-to-date. To update ADT, in eclipse go to: Help -> Check for updates. Select the necessary entries like: Android Development Tools and update them.
Hopefully one of these solutions will solve your problems :-).
