Gson is outdated a bit with the last commit done quite some time ago. We also had implemented the Moshi library in our Gradle dependencies and these are the 2 reasons why we decided to move away from GSON.

Recently I played around with a library that is used in multiple projects. This library has a huge list of dependencies like: coroutines, rxjava, navigation library from Google, material library, custom edit texts that come from 3rd party libraries and many more. Basically this library has also a rich set of screens available to the users that open given certain conditions. But our issues was bigger.

The idea of this post is really simple. If you don’t know the details around RxJava – don’t implement it in a project which has the idea of earning money.

Wonder how to check the network connectivity in Android? There is a new API that you can use but there aren’t many tutorials how to do it. Here is our simple way:

The RxJava approach
I am currently working on an app where the devs before me took this strange decision in regard to the refresh token mechanism – have a single entry point of the app which is called every time whenever you need to have a fresh token. What I mean is this:

Problem
Each Android app has an authentication mechanism or at least most of them do. What this auth mechanism does is that it refreshes an access token using a refresh token every N minutes. In our case these N minutes are 7. And now the question is: How do I implement this?

Testing data classes in Kotlin
As we all know, data classes are final by default on Kotlin and if you try to use Mockito and mock such a class, you will get an exception. What you need to do is add this file:

Running unit tests for ViewModels on Android where you have LiveData objects can be tricky. It is very possible that you get this exception:
java.lang.RuntimeException: Method getMainLooper in android.os.Looper not mocked.

I recently had a very strange bug when it comes to using a BehaviorSubject inside the object that I am testing.

I am using axios to scrape some data from some websites. Currently, I hit the case where the encoding of the website is in windows-1251 and the response I got from the request wasn’t readable at all.
