Answer 1

Delete all your import statements from the class where you are getting this error message.

Then press ctrl+shift+o

Answer 2

I have removed the following line and it worked for me.

import android.R;

Answer 3

I changed

   import android.R;

to

 import your.application.packagename.R;

And project ->clean still the error.

But when I Run the project the error automatically gone, may be Eclipse problem.
