Question

I am using AndEngine for my game. In that I want to give option to user when they click on an image, one alert dialog should pop up. my code is below.
here is the method

@Override
protected Dialog onCreateDialog(int id) {
    switch (id) {
    case 1:
        AlertDialog.Builder builder = new AlertDialog.Builder(MyGame.this.getApplicationContext());
        builder.setMessage("Hello");
        AlertDialog alert = builder.create();
        return alert;
    default:
        return null;
    }       
}

and I am calling this method by this statement :

{
onCreateDialog(1).show();

}

And i am getting this error message :

E/AndroidRuntime(672): android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application

Answer 1

onCreateDialog(1).show(); is wrong.
Call showDialog(1); instead.

And also change your Builder like this:

AlertDialog.Builder builder = new AlertDialog.Builder(MyGame.this);
