Overview of this book

NativeScript allows you to build a fast cross-platform application that has a native UI. NativeScript is a true cross-platform framework that generates native speed applications using the native components of the host platform, all using JavaScript. Although NativeScript allows you to build your application in JavaScript, you have full access to the host OS from your code, allowing you to easily tweak or use new platform features instantly at native code speeds. Whether you have already developed multiple applications or zero applications, this book will help you to develop your next application in a cross-platform framework quickly, saving you a massive amount of time and money. This book concisely shows you NativeScript’s built-in framework that allows you to rapidly develop a fully-working compiled cross-platform application in just a few chapters. It starts by laying the foundation of NativeScript and working through the fundamentals to create a basic shell of the application. Moving on, you’ll see how to build a full-fledged application step by step. We’ll show you how to use plugins, and how to communicate with the native OS libraries easily so that you can customize your application as if your app was created in Java or Objective C. We then deal with the issues that arise from being cross platform and compensate for the different screen sizes, screen resolutions, and device abilities. Finally, we progress to testing and deploying your app.

Device differences

Now that you have got a handle on how to build the resources into your application, the final item is dealing with physical differences in devices. You never know what type of device your application will be running on. The only thing you can really count on in a device is that the device will have a screen. The best impression you can give your customers is an app that doesn't crash, even if it doesn't support the device they are trying to run it on.

Each device will have different sensors and different accessories, and some might even have a physical keyboard. Take the Samsung Galaxy S4 phone. It came with sensors to detect altitude, humidity, and temperature. You might guess that the Samsung Galaxy S5 would also have the same sensors. When Samsung released their new flagship phone, they actually removed or disabled the Humidity and Temperature sensors. Fast forward to the new Samsung Galaxy S6, they now removed SD card support. Despite being flagship devices, Samsung...
