Android Studio and Firebase - "Message Board" Part 3

Creating the "Message Board" application using Android Studio and Firebase in the Kotlin programming language . This is the third part 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 to a database on the cloud in real time.

In this part: Moving to a new version of the library to select a photo with Pix Image Picker. Let's create code to upload multiple photos to Firebase Storage. We are writing code to display ads in the form of a list. We create a screen for viewing advertisements and photos using ViewPager. We write code to send an email and call the ad owner. Update the onActivityResult() function. We are writing code to display a Google account avatar. We do "Pagination" - receiving ads in portions when scrolling down. We correct some errors and start making a FilterActivity to select a filter by which we will get the necessary ads. We create the ability to download ads from different categories. In this part the main part of the code will be finished. There remains part 4 to complete the project in which we will add in-app purchases, search and complete filtering, plus we will eliminate errors that may appear in the process.

The course is intended for beginners who have already installed Android Studio and have little skill 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.
