Google AI Studio to Play Store Series Part 1
____________________________________________________________________________
Welcome to Part 1 of the Google AI Studio to Play Store series.
In this tutorial, you will learn how to build a Play Store ready Android app inside Google AI Studio, add Google official AdMob test ads, install and test the app on a real Android phone, and prepare the project for the next steps.
Important:
In this first video, we are using Google official AdMob test IDs only. Do not use real AdMob IDs while testing your app. In the next videos, we will create a real AdMob account, get real AdMob App ID and Ad Unit IDs, replace the test IDs, generate a signed AAB, and upload the app to Google Play Console.
