The key benefit of Delphi in mobile development is that you can design your app once and, from the same source code, you can natively compile it for both Android and iOS. This chapter is exactly about this capability. We are going to first install Delphi, create a simple one-button "Hello World" app, and then run the same app on Google Nexus 7 and on Apple iPhone 6S.
The Integrated Development Environment (IDE) is where the programmer spends the most of the time. Learning best practices of using the IDE will pay off in the future and will increase your developer productivity. Before going into building apps, you need to feel comfortable working in the IDE.
The objective of this chapter is to install the Delphi IDE, learn basic IDE functionality, and prepare it for mobile development.
