The create method return an instance of AlertDialog

Instead of initializing it to the Dialog when you call the create method of the AlertDialog

Dialog dialog = startGameDialog.create();
dialog.show();

alertDialog.show();

use the currents activity context rather than using the whole application contex.t

Context context = Your_activity.this;

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle(R.string.first_run_version_title)
    .setNeutralButton(R.string.ok_menu_button, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {
            // code to run here
        }
    });
AlertDialog alert = builder.create();
alert.show(); // <-- Forgot this in the original post
