I hope you have installed and tested the features in the card app 123Flip in play store in your android device. This game is an extension to Raul Pandey video tutorial “Build and Publish an Android App – Full Course with Kotlin”. I recommend to view his tutorial video below before moving on to the next section.
The extended codes in the app includes:
- audio sound,
- countdown timer,
- timer setting,
- google sign-in,
- storing to firebase,
- implement credit card payment using stripe gateway,
- localized languages
- Monetize via Admob, and
- publish the app to google play
