title: r.string error "cannot be resolved or is not a field"
body: <p>I just opened an older android app project and all of a sudden numerous R.string._var_Name errors were found.  If I add "import android.R" then the _var_name becomes an issue saying "cannot be resolved or is not a field".  The translation is in /res/values/strings.xml .  Any ideas why the error exists?</p>
