Android Studio and Firebase - "Message Board" Part 4

Creating the "Message Board" application using Android Studio and Firebase in the Kotlin programming language . This is part 4 of the course. Firebase Real Time Database allows us not to worry about how to set up a server for a database on the cloud, but to worry only about our application. Using Firebase we write code only for our application, which can write and read in real time to a database on the cloud.

In this part: We fix some errors in our application. Creating code for editing photos in Firebase Storage. We are finishing the code for filtering ads. We add advertising to MainActivity and add in-app purchases to disable advertising_ namely, the user will be able to become a premium user after payment, then all advertising will be removed. In-app purchases can be used for any other purposes, we will learn all this in this course. We publish the application on the Play Console and set up in-app purchases. In the last lesson, we set up login with a Google account for the working version, since when we upload to the market we will have a different fingerprint of the application. For this reason, we must get a fingerprint of the working version of the application and add it to Firebase, test in-app purchases and login with a Google account.

The course is intended for beginners who have already installed Android Studioand have little skills in this area. I explain all the steps step by step. Based on this application, you can create your own application Blog, online store, food order and much more.
