Mobile app development using hybrid frameworks has come a long way since initial release in 2008. With the improvements being made to the JavaScript engine and improved processing power available to mobile phones, the major concern people had when they considered developing their apps using the hybrid approach — namely, performance — has all but been eliminated, and cross-platform frameworks have seen a surge in popularity.
We’re going to build a mobile application that pulls data from the Marvel Comics API; the data will show Marvel comics and you’ll be able to choose your favorites. At the end, we’ll create a native build of the project on Android.

As opposed to JavaScript and Python, variables and functions in CSCS are case-insensitive. The primary goal of CSCS is to let the developer write as little code as possible. In this article, Vassili Kaplan explains how you can use a scripting language to develop cross-platform mobile applications. You’ll find examples in both iOS and Android that include placing widgets on the screen, SQLite, Web Requests and JSON parsing.

As with many other topics in software development, testing and test driven development are often made needlessly complex in theory and implementation by placing too much emphasis on learning a wide array of testing frameworks. In this article, Ryan Kay will revisit what testing means by a simple analogy, explore concepts in software architecture which will directly result in a reduced need for testing frameworks, and some arguments as to why you might benefit from an attitude of minimalism for your testing process.

When creating mobile apps, you have to create and maintain the user interface and app logic for both iOS and Android separately: Objective-C/Swift with XCode and Java with Android Studio. That can quickly turn into a pain. With Xamarin.Forms, however, the UI and app logic for your app resides in a single codebase and you get to use a single IDE to maintain it all — saving time and headaches. In this article, take a lap around Xamarin.Forms to see what it can do for you.

Frameworks such as Espresso and Mockito provide easy-to-use APIs that make writing tests for various scenarios easier. The important thing to consider while writing tests is the units of responsibility that emerge as you design the new feature. The unit test should cover all possible interactions with the unit, including standard interactions and exceptional scenarios. In this article, Vivek Maskara will cover the fundamentals of testing and frameworks which developers can use to write unit tests.

Flutter makes building cross-platform mobile applications a breeze. It allows high-performance, beautiful applications to be built for iOS and Android from a single code base. It is also the development platform for Google’s upcoming Fuchsia operating system. In this article, Mike Bluestein introduces Flutter, compares it to other mobile development platforms, and shows how to use it to get started building apps.

Users couldn’t care less about whether a technology is native, an installed web app or a website. What makes users engage and makes shoppers convert is really the experience itself. In this article, Mitch Lenton takes a closer look at PWAs on Android devices and explains how we can pave the way for a new era of browserless web browsing.

In this article, Aidan Sliney is not going to make you the next Instagram, but he will hopefully help you get a nice base level of users that you can grow from. The example app in this article received 100,000 downloads in eight weeks. This is with a marketing budget of zero and very little work since launch. Aidan will cover the basic app store optimizations that will help bring people to your Google Play page. Getting them to download and stay is up to you and up to the value your app provides. Of course, to get traction, you need to pick a topic in which enough people are interested, and then the quality of your build is what is going to help keep these users.

Sooner or later, physical mobile devices will appear in the integration system of every relatively large Android project. The need to fix mistakes, perform non-standard test cases and simply test for the presence of certain features all inevitably require an actual device. Regression testing is one of the most time-consuming tasks when developing a mobile Android app. Using myMail as a case study, Alexey Perfilov would like to share his experience and advice on how to build a flexible and extensible automated testing system for Android smartphones — from scratch.
