Weekend good reads for Android developers, issue #39 (38/2022)

by Michael SzczepanikSeptember 24, 2022September 24, 2022

The weekend is in progress but we are sharing some interesting articles with you:

How to automate your UI testing using Maestro

UI testing is usually ignored. The main reason why it is like that is the complexity of most of test frameworks. The Maestro library changes the way you think about UI testing and in my opinion can be considered as great tool.

Type modelling in Kotlin
Jan Mostert shares several examples of how using Kotlin features can help better model data and errors in your code.

Writing your own CoroutineContext Element

How to pause a coroutine

How to break a coroutine cancellation

As you can see Vasiliy Nikitin created series of blogposts about coroutines which I strongly recommend to review.

Web3 Series: Intro for developers

The first blog of the Web3.0 series from me so if you are interested in NFT, DeFi, Web3 it can be for you.

iOS 16 adoption is better than iOS 15 was

by Danis TazetdinovSeptember 23, 2022

Mixpanel report provides iOS 16 adoption numbers – more than 25% on September 23. This adoption rate is an improvement compared to iOS 15 adoption last year.

10 days after launch in 2021, iOS 15 was installed on just 19.3 percent of devices, as ‌iPhone‌ owners at the time seemed more reluctant to upgrade due to some early bugs. ‌iOS 16‌ may also be more appealing because of the visual changes that it introduces.
