Easier peer reviews and documentation-as-code — At SoundCloud, we are around 20 Android engineers, working in a multi-module project with more than 10 databases, with multiple tables each. And that’s only the Android app! As software matures, more functionality is added, code gets moved, re-written or removed. In the same rhythm, team members change and with…

The story is more common than it seems: a new feature is developed and tested extensively in-house, but only when the client applications are deployed, the engineering team discovers the extra production load and seasonal request rate. A hot-fix is needed! …

When a request to a server fails, it is very tempting to issue another try to the same route, as a way to increase reliability of systems or mask transient problems to the end-users. How often is this a good idea? Never. Well, more or less. Today, many RPC libraries…

Periodically triggered jobs are very common in modern applications, especially in the client-server model: uploading notes, analytics events or backing up data are good examples of timely operations that a developer might decide to trigger at a specific rate, for example once per hour, or at 3 a.m. …

Starting from Android Lollipop, developers have an API that can be used to capture parts or the entire visualization of a device’s screen: MediaProjection. James O’Brien gave a great description of that usage in this article. From Android 10, the MediaProjection API was extended to support the audio capture use-case…

It is a common misconception to think that software development is all about writing code, but in reality, that is not where engineers invest most of their time. Instead, most of the effort is put in designing the application and understanding how it behaves once it is deployed. As applications…

When building any software, we want to provide the best possible experience to our users, giving them the feeling of being in full control and taking the most value out of our applications. …

During I/O 2016, Google announced it was developing a new way to bridge the gap between the web and native apps, by making them as easy to access as a simple click in a link: Instant Apps, made of small data-chunks that can be temporarily loaded on the device with…

Apesar de uma prática já bem estabelecida dos círculos de desenvolvimento de software, principalmente do lado back-end, a Entrega Contínua (Continuous Delivery, no inglês) e a Implantação Contínua (Continuous Deployment) ainda dão seus primeiros passos no desenvolvimento mobile. Neste artigo, vou apresentar a Publishing API (que faz parte da Google…
