Hi,
I want to create a normal AlertDialog. I used the example provided by the android dev docs. I just changed the DIALOG_PAUSED_ID to DIALOG_DELETEDB. If I execute my code and press the button which in return should create the dialog, I get the following error log:

so here are the "relevant" code parts:

define the ID:

private static final int DELETE_DB_ID   = 3;
private Dialog dialog;
static final int DIALOG_DELETEDB = 4;

onCreateDialog(...):

protected Dialog onCreateDialog(int id) {
        switch(id) {
        case DIALOG_DELETEDB:
            // do the work to define the pause Dialog
            AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setMessage("Are you sure you want to exit?")
            .setCancelable(false)
            .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                     Favs.this.finish();
                }
            })
            .setNegativeButton("No", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                     dialog.cancel();
                }
            });
            AlertDialog alert = builder.create();
            alert.show();
            break;
        default:
            dialog = null;
        }


return dialog;
    }

Here I try to "create" the dialog:

@Override
    public boolean onMenuItemSelected(int featureId, MenuItem item) {
        switch(item.getItemId()) {
        case ADD_ID:
            createNote();
            return true;
        case DELETE_DB_ID:
            showDialog(DIALOG_DELETEDB);
            return true;
        }      
        return super.onMenuItemSelected(featureId, item);
    }

As I already said, I just copied the code and changed the name. Unfortunately, I don't understand the error log message.. :/ Somehow I think I don't return the created dialog, but I cannot see "where" my reference is or where/what I have to return...

thanks in advance for help.
