Repository

Setup project

1 - Clone this repository

2 - Open in Android studio

3 - If you are running android N and above, change the computer's IP in the network_security.xml.

The file is located in: Network module > src > main > res > xml > network_security.xml

4 - Find the API Constants file and replace the api url internal const val BASE_URL = "http://192.168.25.7:8080" to your server matching IP. The file is located in:

Network module > src > main > java > com.therealdroid.github.network.config > Constants.kt

You can find the credemtials in the server documentation

Project Decisions

Activities replication instead reusable fragments

It is a fact that login and registration are very similar in terms of functionalities, form fields, and server responses. I could make reusable fragments, repository and datasources but I choose to create another activity for it (register and login). The reason is because in a real situation it will not be similar and going deeper it will have different logic etc.

Rx instead LiveData plus Coroutine.

I’ve followed the same guideline LiveData uses with ViewModel, but I’m more familiar using Rx with MVVM.

Realm database instead Room database.

The reason I choose realm is because I’m not familiar with room and because I did not used google components architecture as well. Realm is used in this project to persist the logged in user.

MVVM

Reusable
Centralize application business logic

To improve

My tests are not working and I didn't had enough time to figure out the problem. This challenge have tests running.
