Howdy. Just getting into android programming and have ran into a snag. My program opens with a splash screen then goes to a menu screen with 3 buttons. The 2 buttons I've coded so far work, but the target class of one crashes. I know the buttons work because I had it go to a temp class I made and it went there fine.

Also, when I only have the basic code in the target class it works.

package com.brggames.dquest;

import android.app.Activity;
import android.os.Bundle;
import android.view.Window;

public class temp extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.hall1);
}

}

That works, but the next one does not work. It crashes.

package com.brggames.dquest;

import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.widget.Button;

public class hallOne extends Activity {

MediaPlayer bclick1;
Button bForward1, bBack1, bLeft1, bRight1, Bpause1, bPlayMusic1;

@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.hall1);


bclick1 = MediaPlayer.create(this, R.raw.bclick1);

Button bLeft1 = (Button) findViewById(R.id.bLeft1);
bLeft1.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
bclick1.start();
}
});

Button bRight1 = (Button) findViewById(R.id.bRight1);
bRight1.setOnClickListener(new View.OnClickListener() {

@Override

I comment out everything and it works. I doubled and tripled checked my AndroidManifest.xml, and for the life of my I can't figure it out. As I said, I'm new and may be missing something very simple. Here is the code with the stuff commented out. the menu code at the bottom works perfectly (the restar button isn't coded yet).
