Android-AlertDialog - doesn't work

Yesterday I had programmed a little AlertDialog with my Android-Phone via AIDE programmed. On the Internet I've found the source code 

AlertDialog alertDialog = new AlertDialog.Builder(AlertDialogActivity.this).create();
// Setting Dialog Title
alertDialog.setTitle("Alert Dialog");
// Setting Dialog Message
alertDialog.setMessage("Welcome to AndroidHive.info");
// Setting Icon to Dialog
alertDialog.setIcon(R.drawable.tick);
// Setting OK Button
alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int which) {
        // Write your code here to execute after dialog closed
        Toast.makeText(getApplicationContext(), "You clicked on OK", Toast.LENGTH_SHORT).show();
    }
});
// Showing Alert Message
alertDialog.show();

I have tested this in AIDE and it's working, then I've tested it within AndroidStudio and it didn't work. Why does it work in AIDE and not in Android studio?

AlertDialog.Builder alertDialog = new AlertDialog.Builder(
                AlertDialogActivity.this);

Edit first line as above since you need to set builder before creating alertDialog

Complete code as follows:

AlertDialog.Builder alertDialog = new AlertDialog.Builder(
                AlertDialogActivity.this);
// Setting Dialog Title
alertDialog.setTitle("Alert Dialog");

// Setting Dialog Message
alertDialog.setMessage("Welcome to AndroidHive.info");

// Setting Icon to Dialog
alertDialog.setIcon(R.drawable.tick);

// Setting OK Button
alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
        // Write your code here to execute after dialog closed
        Toast.makeText(getApplicationContext(), "You clicked on OK", Toast.LENGTH_SHORT).show();
        }
});
AlertDialog alertDialogMain = alertDialog.create();

// Showing Alert Message
alertDialogMain.show();
