Portfolio

Another variation of the Traffic Signs app designed for Salam School.
This app uses Firebase Authentication, Crashlytics, Realtime Database and, Storage.
I've updated it's code to use Kotlin and Architecture components. The app is now using Room persistent database, Viewmodels and Livedata .

Android app Salam School MCQ

An MCQ quiz for traffic signs exam .
The app randomly gets 30 questions for the user each exam.
There is preferences dialog, tracking answers , index of questions , and ability to get all questions in a specific category.

Database used is Firebase Realtime database , and recently I migrated to Firestore
Questions are displayed one by one, but some lists as the signs information list, is using a recycler view, same for answers list .
Sound plays on click using sound pool
User authentication is also by Firebase
There are some other features that was implemented recently as well:
One activity app
Navigation graph
ViewModel
and I removed the local room database now depending totally on Firebase

I was concerned about security so I used progaurd minify and shrink code .
Minimum SDK was set to 19 to cover as much devices, so i had to set multidex to true.

Traffic Signs MCQ quiz

This is one of my published Android apps on Google Play store.

The app features:
Firebase User Authentiation
Firebase Firestore

View Binding
among others....
