In Eclipse keep getting error "R cannot be resolved as a variable"

In an array adapter I keep getting the error "R cannot be resolved as a variable" and I have know idea why this is happening and all I could understand from a quick google search is that R is a file automatically generated that shouldn't be causing any errors. I have tried refreshing and cleaning my project and that hasn't worked and the R.java file is definitely present in the "ten" folder. Here is the code that is giving me errors.

package com.bernard.beaconportal.adaptor;

import com.bernard.beaconportal.R;

import android.content.Context; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.ArrayAdapter; import android.widget.ImageView; import android.widget.TextView;

public class MobileArrayAdapter extends ArrayAdapter<String> { private final Context context; private final String[] values;

public MobileArrayAdapter(Context context, String[] values) {
    super(context, R.layout.activity_homeworkdue_twopane, values);
    this.context = context;
    this.values = values;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View rowView = inflater.inflate(R.layout.activity_homeworkdue_twopane, parent, false);
    TextView textView = (TextView) rowView.findViewById(R.id.label);
    ImageView imageview = (ImageView) rowView.findViewById(R.id.logo);
    textView.setText(values[position]);

    // Change icon based on name
    String s = values[position];

    System.out.println(s);

    if (s.equals("1")) {
        imageview.setImageResource(R.drawable.english);
    } else if (s.equals("2")) {
        imageview.setImageResource(R.drawable.mathematics);
    } else if (s.equals("3")) {
        imageview.setImageResource(R.drawable.global_studies);
    } else if (s.equals("5")) {
        imageview.setImageResource(R.drawable.science);
    } else {
        imageview.setImageResource(R.drawable.half_life_3_where_are_you);
    }

    return rowView;
}

}

Did you update ADT? If yes, Could you please update your build tools and check again? It will be useful if you can post the versions
