Ok guys, I have a button in android that i'm trying to use to update 8 EditText Views with different random numbers. Everything works up until I click the button. It appears I am missing a resource according to the debugger, but I'm not sure what. I've tried several different ways of implementing the button. Here is what I have after looking at several posts.

import java.util.Random;

import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

public class MyCharNewChar extends MyCharActivity {


private OnClickListener randomButtonListener = new OnClickListener(){
    public void onClick(View v) {
        //Button creates a set of random numbers and updates the values
        //of the EditText views.

        Random rand = new Random();
        int STR = 1 + rand.nextInt(12);
        int AGI = 1 + rand.nextInt(12);
        int DEX = 1 + rand.nextInt(12);
        int WIS = 1 + rand.nextInt(12);
        int INT = 1 + rand.nextInt(12);
        int CON = 1 + rand.nextInt(12);
        int HP = 1 + rand.nextInt(20);
        int AC = 1 + rand.nextInt(6);

        EditText str = (EditText) findViewById(R.id.str);
        str.setText(STR);
        EditText agi = (EditText) findViewById(R.id.agi);
        agi.setText(AGI);
        EditText dex = (EditText) findViewById(R.id.dex);
        dex.setText(DEX);
        EditText wis = (EditText) findViewById(R.id.wis);
        wis.setText(WIS);
        EditText intel = (EditText) findViewById(R.id.intel);
        intel.setText(INT);
        EditText con = (EditText) findViewById(R.id.con);
        con.setText(CON);
        EditText hp = (EditText) findViewById(R.id.baseHP);
        hp.setText(HP);
        EditText ac = (EditText) findViewById(R.id.baseAC);
        ac.setText(AC);
        }
    };

@Override
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.newchar);
    Button randomButton = (Button) findViewById(R.id.randomButton);
    randomButton.setOnClickListener(randomButtonListener);
}


}

Here is the xml:

        android:text="@string/randomButton"
        android:textSize="16dp"
        android:clickable="true"/>

    </LinearLayout>
</LinearLayout>

I have also tried setting the onClick in xml to setup a specific onClick method. Still the same error so I must have a problem elsewhere. Any suggestions would be great!
