can't be resolved...pls tell me the reason..thanks in advance

Are you running this on a tablet or non-phone device?

I'm not sure why the Sqlite import would be wrong, but a tablet with non-stock android might be lacking the entire telephony package.

I'm fairly sure you need the entire AOSP source to build that app.

Those imports are not part of the public API as far as I know.

It happens because these imports are unavailable in SDK version under which you're trying to compile project. Just select Android SDK 2.2 or SDK 2.3 and everything will be ok...
