Android : Getting the value of an EditText field

I want to have the user input the amount of players and then when the button is pressed it submits the amount and moves to the next screen. But when I test it, the app just crashes and I get the error, "Unhandled event loop exception". here's my code:

package com.example.trivia;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.text.Editable;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;


public class MainActivity extends Activity {

public static int players;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    //locates widgets
    Button submit = (Button) findViewById(R.id.submitPlayers);
    final EditText howMany = (EditText) findViewById(R.id.editText1);

    submit.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            //gets number of players from text field then goes to next activity
            players = Integer.parseInt(howMany.getText().toString());

            Intent intent = new Intent(v.getContext(), PlayerMenu.class);
            startActivityForResult(intent, 0);

        }
    });
}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

}
