Desktop Apps and Mobile Bridges

Although, in this book, we are primarily focused on building mobile apps with Delphi and FireMonkey, this chapter touches on the development menu of desktop applications and on the development of applications that work seamlessly on desktop and mobile, with a single source code base. The chapter will offer specific tips and recommendations for Windows, macOS, and Linux, and it will focus on what Delphi offers to create desktop and mobile applications that interact directly, using a technology called app tethering.

Given that FireMonkey is a great library for desktop development, it is important to focus on this area of the library, besides covering iOS and Android support. A significant advantage of FireMonkey is its ability to target desktop and mobile with a single source code, and the goal of this chapter is to help you understand this powerful feature while exploring specific examples.
