This article is the first part of a tour around the Android platforms: Android TV, Wearable and Auto. We wrote down the crucial things that you should know before you get into building apps. We will not show you how to build applications for these particular platforms step by step, but you can find more resources which will help you do so on the Android Developer site. What we want to do here is show you the minimum requirements and restrictions you must know before you start. Hopefully this will help you build an efficient and effective application.

I’m amazed how much mobile developers despise SQL. It’s fast and efficient way of storing data, proven in battle in so many years. I guess the reason of that for many of them, myself included, is the way we were taught at universities. For a beginner programmer, it’s quite a challenge to dive in into SQL, with its complicated queries and non-intuitive relations. I remember being overwhelmed and repulsed by it. For the same reason, I hated C for so long. I guess it takes time to appreciate a technology fully, but the feeling of accomplishment after completing a low-level language project is much bigger than creating something with the use of easier, ready-to-go solutions.

Nowadays, technology is growing at an unprecedented rate – the trend concerns especially technologies related to mobile. This trend has been brought about by the continuous development of mobile devices and their software. It is also related to the newly emerging technological branches: Internet of Things (IoT), Augmented Reality (AR), Machine Learning, etc. In a company such as Netguru, it is extremely important to keep up-to-date with all the technological news and tools that could improve development. To accomplish this goal, we created two R&D teams: one for Android and one for iOS. Their task is to research and develop ideas based on new technologies and develop the skills of the developers so that they can provide the highest level of services.

Android development requires modern solutions, a mobile applications store big amount of data. SQLite project, a default Android database engine was launched in 2000 and has some alternatives like pretty popular Realm and quite new ObjectBox. Both products comprise NoSQL database and have a few things in common: DB built for objects, ACID properties, Multiversion Concurrency Control (MVCC) architecture, core written in C++, reactive data observation and a multiplatform.

Google I/O 2017 was quite revolutionary. We’ve seen a lot of amazing new products announced and heard that Google will be investing a lot into machine learning-related technologies. This year’s I/O was also extraordinary for Android developers, as we’ve finally received official support for Kotlin (yay!) and a brand new collection of Android libraries called “Android Architecture Components”.

Android Components Comparison: MVVM vs MVP

It’s 2017 and 9 years after android emerged, Google on it’s yearly I/O conference finally left the status quo and became somewhat less liberal in terms of recommended apps architecture. For years folks at the Android Team didn’t really join any architecture-related discussions, as they only cared that developers properly use Android SDK entry points, aka Components (Activity, Service etc.).

Every one of us wants the same for our apps. We want them to contain a richer feature set, appear more stable, and be used by more users, not to mention having quicker development cycles. This can cost a lot of your most important resources: time and money. Wouldn’t it be perfect if someone has already made the solution ready to be used as a service?

You know the feeling: too much to do, and too little time to do it. We’ve all been there. Writing good code while under pressure is obviously a great challenge. Fortunately, when it comes to development on Android, there are tools to speed up the process. We asked our Android Developers what tools are their must-haves at work. Check them out and make your work easier.
