Program crashes when trying to create AlertDialog

Question

I'm having difficulty when making an alert dialog, the code for it is here:

public void setp2(View v){
        p2 = (TextView)findViewById(R.id.p2);
        AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(getApplicationContext());
        alertDialogBuilder.setTitle("Please enter player 2 name");
        alertDialogBuilder.setMessage("MESSAGE");
        alertDialogBuilder.setCancelable(false);
        alertDialogBuilder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int id) {
                // TODO Auto-generated method stub
                dialog.cancel();
            }
        });
        AlertDialog alert = alertDialogBuilder.create();
        alert.show();   

}

Whenever I run this it crashes the logcat looks like:

I've looked through it several times and can't seem to find where it's going wrong, was wondering if anyone could help out?

I don't see `setp2()` in your stack trace, the problem is in your AsynTask's `doInBackground()`, post this method and mark line 93. — Sam, Apr 14 '13 at 05:17
Hmmm how odd my Logcat doesn't seem to have saved over the previous log I saved, should be sorted now — Coombes, Apr 14 '13 at 05:17

Caused by: android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application

It appears the Context is bad, sometimes getApplicationContext() returns odd results... Try changing this:

new AlertDialog.Builder(getApplicationContext());

To:

new AlertDialog.Builder(MainActivity.this);

Check the answer by commonsware in the link

When to call activity context OR application context?

i have deleted my answer since the answer is the same. Copied the link and posted the same in your answer. Thought the link might help. – Raghunandan Apr 14 '13 at 05:36
Thanks RaghuNandan, you respected SO's rules :) – AAnkit Apr 14 '13 at 05:37
@Raghunandan Ok, that is a good link. I upvoted one of your other answers to say thanks. (Your answer wasn't wrong, it's just silly to have the same answer duplicated.) – Sam Apr 14 '13 at 05:42
