It is not uncommon for developers to find themselves in need of a UI component that is either not provided by the platform they are targeting or is, indeed, provided, but lacks a certain property or behavior. The answer to both scenarios is a custom UI component. The Android UI model is inherently customizable, offering the means to create custom UI components in various ways.

Whether you’re an avid angler or an app developer, you may be interested in taking a closer look at the development of a fishing app, which involved some of your fellow Toptalers. The goal was to create an app that would be truly useful in a professional fishing setting, while at the same time meeting a hard deadline. Since Fatsack Outdoors wanted to launch the app at one of the biggest fishing tradeshows of the year, the deadline was non-negotiable.

Detecting objects of interest in images has always been an interesting challenge in the realm of computer vision, and many approaches have been developed over recent years. As mobile platforms are becoming increasingly powerful, now is the perfect opportunity to develop interesting mobile applications that take advantages of these algorithms. This article walks us through the process of building a simple iOS application for detecting objects in images.

Google announced Android M at its annual I/O dev conference in late May, and the new OS is coming to our beloved Android devices later this year. Android 6.0 is more of an evolutionary step, whereas Android 5.0 was a big leap forward thanks to its 64-bit ART runtime and all new Material Design. However, Android M should not be dismissed as a minor update. In this post, I will try to explain why.

With Dalvik out of the picture, many people expected Google's new 64-bit capable ART runtime to stick around for years, which it probably will, but it will get a major overhaul in the near future. In addition to offering support for 64-bit hardware, ART also introduced ahead-of-time (AOT) compilation, while Dalvik was a just-in-time (JIT) compiler. Throw in new 10-core ARM processors and Intel mobile processors based on three different architectures, and you end up with spicy, Google-style hardware gumbo.

While the Apple Watch is on track to be a commercial success for Apple and its shareholders, technologists are still not entirely convinced smartwatches have what it takes to conquer the market, at least not yet. What does this mean for developers? What are the implications for other smartwatch platforms and companies behind them?

iOS 8 introduced a new concept called App Extensions. This new feature did not break down the walls between the applications, but it opened a few doors providing gentle yet tangible contact between some apps. The latest update gave us an option to customize the iOS ecosystem, and we are eager to see this path opening up as well.

Location-based applications on our mobile devices have changed the way we interact with mobile technology. The list of these applications is extensive and has had a major impact on our lives. This article walks us through a step-by-step tutorial of how to determine the location of an Android device using Google Location Services API.
