Delphi Cookbook - Second Edition

By: Daniele Teti

Overview of this book

Delphi is a cross-platform Integrated Development Environment (IDE) that supports rapid application development for Microsoft Windows, Apple Mac OS X, Google Android, and Apple iOS. It helps you to concentrate on the real business and save yourself the pain of wandering amid GUI widget details, or having to tackle inter-platform incompatibilities. It also has a wide range of drag-and-drop controls, helping you code your business logic into your business model, and it compiles natively for desktop and mobile platforms. This book will teach you how to design and develop applications, deploy them on the cloud platform, and distribute them within an organization via Google Play and other similar platforms. You will begin with the basics of Delphi and get acquainted with JSON format strings, XSLT transformations, unicode encodings and various types of streams. We then move on to more advanced topics such as developing higher-order functions and using enumerators and RTTI. You will get an understanding of how Delphi RTL functions and how to use FireMonkey in a VCL application. We will then cover topics such as multithreading, using the parallel programming library and putting Delphi on a server. We will also take a look at the new feature of WebBroker Apache modules and then ride the mobile revolution with FireMonkey. By the end of the book, you will be able to develop and deploy cross-platform applications using Delphi .

Introduction


There are situations where if you need a particular Android or iOS feature, FireMonkey does not help you. FireMonkey does a very good job in supporting all the common mobile features, but not all the APIs have been already imported, polished, and wrapped in nice Object Pascal reusable classes or components. What can you do in these cases? The good news is that you can import classes from the underlying SDK (and NDK in case of Android) and wrap them just like Embarcadero did in the FireMonkey platform.

In this chapter, we will see some classes import examples. Keep in mind that the code using imported classes is not cross-platform. That is, if you import an Android SDK class and your code uses it, you lost the possibility to compile that specific code for iOS. However, you can, as usual, use some IFDEFs to statically select the Android specific code from the iOS specific code. Moreover, in the last recipe, we'll see how to use one of the most powerful Android features: the services...
