Developing Multi-Device Applications

Go Up to Multi-Device Applications Index

You can use RAD Studio on the Win32 platform to develop multi-device applications that run on other platforms.

Supported Platforms

RAD Studio supports multi-device application development for the following platforms:

• 32-bit Windows
• 64-bit Windows
• OS X
• 32-bit iOS Device
• 64-bit iOS Device
• iOS Simulator
• Android

Only Delphi supports iOS Simulator. All other platforms are supported by both Delphi and C++Builder.

Supported Frameworks and Libraries

RAD Studio supports three major libraries and several platforms. The following table lists the target platforms supported by the libraries in RAD Studio:

• FMX is FireMonkey (FMX.Forms, and so forth).
• RTL (run-time library) contains the convenience and utility functions and types (found in System.SysUtils and System.IOUtils, among others) that support both VCL and FMX.
• VCL is the longstanding Visual Component Library.

The following table summarizes the platform support by the various libraries in RAD Studio:

Library\Platform	Win32	Win64 (Delphi and C++)	OS X	iOS (Simulator and Device)	Android
FMX	Yes	Yes	Yes	Yes	Yes
RTL	Yes	Yes	Yes	Yes	Yes
VCL	Yes	Yes	Not supported	Not supported	Not supported

Note: The table above is a high-level representation of library support for platforms.

Some exceptions exist in RTL and VCL support for specific platforms. For example, BDE is not supported on Win64 or OS X.

Types of Multi-Device Applications You Can Create

• Mobile apps that run on iOS and Android devices, as well as the iOS simulator
• FireMonkey (OS X, Win64 -- native Win32 is also supported)
• VCL Forms (Delphi and C++ Win64)
• DataSnap clients (OS X, Win64 -- native Win32 is also supported)
• DataSnap servers (Windows only)
• DataSnap connectors (iOS Free Pascal, iOS Objective C, Blackberry Java, Android Java, Windows Phone 7 C#Silverlight)
• Console applications
• 64-bit Windows applications are considered cross-platform because the RAD Studio IDE is a 32-bit Windows application

Developing a Multi-Device Application

The basic development cycle for a multi-device application is as follows:

1. Configure your development system and RAD Studio to support the target platform.
   • If your development system runs 32-bit Windows and your application targets 64-bit Windows:
     1. Connect your development PC to the 64-bit PC.
     2. Install and run PAServer, the multi-device server, on the 64-bit PC.
     3. Create a connection profile that describes the connection to the Platform Assistant server on the 64-bit PC.
   • If your application targets OS X or iOS:
     1. Connect your development PC to the Mac.
     2. Install and run PAServer, the multi-device server, on the Mac.
     3. Create a connection profile that describes the connection to the Platform Assistant server on the Mac.
     4. Add an SDK to build your application.
2. In the IDE, create and configure a multi-device project:
   1. Add the target platform that you want.
   2. Activate the target platform.
   3. Configure the target platform with a connection profile and an SDK if needed.

      Note: If you use a connection profile, you can test the connection on the Connection Profile Manager page.

3. Compile and build as usual.
4. Debug using the integrated multi-device debugger.

   Keep in mind that running a multi-device application requires the IDE to deploy the application.

5. Deploy your multi-device application.
