System Information
System information features enable your application to retrieve information about fixed platform features or device capabilities by querying system information keys.
| Category | Description |
|---|---|
| Platform information | Platform or API version, screen coordination system, and CPU and FPU architecture. |
| Device capabilities | Sensors, networks, connections, and additional components. |
To obtain the information, query a system info key. The keys are listed in the following tables.
- Feature keys:
- System keys:
| Note |
|---|
| Some device-specific information keys look similar to feature keys for application filtering, but their usage differs. Feature keys for device-specific information are used to determine whether the feature is supported in the system. Feature keys for application filtering let the Tizen store filter applications based on features. |
