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 .

Letting your phone talk – using the Android TextToSpeech engine


In this recipe, we'll do some very fun stuff. On your Android phone, run an app with a listening UDP server on it. When another application, in our case a VCL application, sends a UDP broadcast with some text, the android app will pronounce the text using the android TTS engine.

Getting ready

The first thing to do is to import the TTS classes from the android SDK in our Delphi project. That is not a simple task; however, luckily, someone already did the job. Indeed, Jeff Overcash, the maintainer of the InterBase Express Components (IBX), wrote the Android Text To Speech JNI Translation. His translation with a simple demo app is available on CodeCentral (http://cc.embarcadero.com/item/29594).

In this recipe, we'll use the imported classes to let our android device read the text sent via UDP broadcast. Note that the message will be read by each device that receives it. Thus, if you have 2, 3, or 4 phones, you will listen to the message...
