R.layout.main cannot be resolved

Question

Hi, Using Eclipse on win XP. I've previously created an app or 2, but am now working on the 'real' version and get the above error.

I was having funnies creating a 1.5 version, so have started a new project for 2.1.

package xxx.guest;

import android.R;
import android.app.Activity;
import android.content.Context;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.TextView;

public class briefme extends Activity {

 private String strURL;
           ........
           ........ 

 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main ); 

Project as below (note I've removed some names for confidentiality reasons!)

Any ideas what's gone wrong?

Thanks,

Martin.

Answer 1

I would try refreshing, if that doesnt work, close and open the project.

If those two fail, delete and re-create R(it should auto-generate)(copy it just to be on the safe side).

I've have this happen to me a few times and those are the three things I usually do to fix the error.

Edit: Also try changing your import:

import android.R;

to:

import you.package.R;

Or deleting that line.
