Abstract

One set of instructions is generated in part by compiling application-specific source code. When natively executed on a platform provided by a device, the set of instructions provides an application. Another set of instructions is generated in part by compiling the same business logic source code. When natively executed on another platform provided by another device, the other set of instructions provides the same application. The business logic source code is substantially free of code specific to any platform. Moreover, the business logic source code defines substantially all application-specific functionality of the application.

9. The method of claim 6, further comprising generating a shell application package that comprises computer-executable instructions that when executed on a device cause the device to provide a shell application that appears to be performing operations of the application, the shell application actually sending navigation requests to the application module and receiving serialized interface data from the first binding module, the application module and the first binding module operating at a server system.

10. The method of claim 6, wherein generating the set of instructions comprises:

generating a client package that comprises instructions that define functionality of the first binding module, the client package suitable for installation on computing devices that provide the first platform; and
