Android tutorial (2018) - 60 - Building an Alert Dialog

The recommended way of creating dialog in your android app is by using a DialogFragment.

If you use the DialogFragment for creating the dialog then it will effectively handle Dialog's life-cycle events such as user press the back button, device screen orientation changes etc.

Create a class that extend DialogFragment and override the onCreateDialog method in it. You can create your dialog from this method by using an AlertDialog builder object .

Finally you can display the dialog by calling the show method on an instance of your DialogFragment Sub class.
