This page summarizes the known differences between the most popular mobile platform development options for handheld devices such as a PDA or mobile phones. It is not intended to be an absolute guide to the various mobile development platforms, instead it is to help guide developers in choosing a mobile platform for development on Information appliances. Wherever possible, the comparisons are relative, supporting a more neutral point of view
Mobile Development Comparison
| Symbian | J2ME | Python | Flash Lite | .Net Compact | Microbrowser Based | BREW | |
|---|---|---|---|---|---|---|---|
| Overview | Ideal for speed-critical applications with a long timeline and options for significant development investment. | Ideal for an all-around solution, if the J2ME platform provides the needed functionality | Ideal for initial prototyping and concept testing when functionaluty falls outside J2ME, and easier to get started with than Symbian | Ideal for Graphics-heavy options with a market that can support the FlashLite player | Ideal for deployment on homogeneous Pocket-PC devices | Ideal for lightweight functionality, a web-interface for an existing application with no latency concerns, or a widely varying platform base | Unknown |

Evaluation Criteria
- Learning Curve is an approximation of how difficult is would be for a developer with reasonable proficiency in the Foundation language to both construct a Hello world on the mobile platform, as well as relative ease of accessing advanced mobile features. By nature, this will be the most difficult to keep a neutral point of view on, and is not intended to be a debate on the relative quality of C# vs. Java.
- Debuggers must be capable of
- Settable Breakpoints
- Step-through execution
- Mobile Integrated Development Environment evaluation is based on the availability of
- Autocomplete
- Syntax highlighting
- Refactoring
- Debugging
- Emulator is based on availability and integration with development emulation options
- Low-Level Access includes the capability of accessing various forms of mobile device functionality
- Full-resolution digital photos
- Video capture
- Cell Tower ID
- File access
- Crippled Providers is when mobile device carriers restrict hardware functionality
- Restricting loading of new applications
- Disabling or limiting Bluetooth access
