Errors on eclipse console as soon as I create a new activity

Question

I'm getting the following two errors when I create a new activity on the console:

[2013-06-20 19:06:12 - Pingcampus] 'default' is not a best match for any device/locale combination.
[2013-06-20 19:06:12 - Pingcampus] Displaying it with ', , Locale Language ___Region __, , sw320dp, w320dp, h533dp, Normal Screen, Long screen aspect ratio, Portrait Orientation, Normal, Day time, High Density, Finger-based touchscreen, Soft keyboard, No keyboard, Hidden navigation, No navigation, Screen resolution 800x480, API Level 17' which is compatible, but will actually be displayed with another more specific version of the layout.

This is also restricting the R.java file to be created and hence giving the error on the source code i.e.

R cannot be resolved to a variable

Answer 1

Restart your eclipse might be solve this or try this

Window --> Show View --> Problems. This should display a list of the specific problems that Eclipse is 'worried' about.

generally clean and build the project hope it work
