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 .

Using Java classes in Android apps with Java2OP


In this recipe, we will talk about the Java2OP command line utility. Java2OP.exe ("Java To Object Pascal") is a command-line tool that you can use to generate Delphi native bridge files from Java libraries (JAR or class files). Once having generated the Object Pascal files describing the Java needed classes, you can use them to provide your Delphi applications access to those Java libraries on Android.

Java2OP.exe is included in the most recent Delphi versions and is available at the following path: <RAD Studio>\bin\converters\java2op\java2op.exe.

Getting ready

This recipe is an upgraded version of the Using Android SDK Java classes recipe. Indeed, while in the first recipe, we created the Object Pascal files by hand reading the Android documentation, here we'll use the Java2OP.exe utility to automatically generate them. This is the process that you will use 90% of the time (if you have a modern version of Delphi); however, the first recipe...
