Thanks in advance

It looks like there might be something wrong with the emulator you are trying to launch. Have you tried launching the emulator directly from the AVD Manager? — CocoNess, Oct 04 '12 at 07:14
Yes, rather than running the application.. First I launched the emulator from AVD followed with running the app by selecting the launched emulator..Still getting the same error. — Shweta, Oct 04 '12 at 07:18

Importing R.java from other project might create a problem.

Try this: right click on the project -> Android Tools -> Fix Project Properties.

Than check if the problem is solved or not.

One more thing, as far as I know GPS will mostly work on the Physical Device and not on Emulator/Simulator.

Tried right click on the project -> Android Tools -> Fix Project Properties., but still facing the same issue.Also , iam not using GPS in my app – Shweta Oct 04 '12 at 07:15
Try: Project -> Build Automatically than Project -> Clean, and than Project -> Android Tools -> Fix Project Properties. Also don't forget to select Project -> Build Automatically. – Rishi Oct 04 '12 at 07:20
Its still showing an error..Is there any possibility that this might happen cos some of the libraries of eclipse or android might be missing ?? – Shweta Oct 04 '12 at 07:30
I don't think so, but you can try updating packages from Help -> Check for Updates from eclipse and than import your project. Also one more thing is if the project you are importing was created in the latest eclipse version and you are importing in the older eclipse version than it might create a problem. – Rishi Oct 04 '12 at 07:33
and what about the project you are importing? in which version it was created? – Rishi Oct 04 '12 at 07:58
