Geolocation sample widget
The latest in our Widget Samples series is the Geolocation sample widget, which demonstrates how to use the JIL geolocation API.
Location-awareness can add a unique dimension to your mobile apps, enabling you to create presence-based services and include geotagging, mapping, and navigation functionality. The JIL geolocation API is easy to use, does exactly what it says, and makes it easy to give your apps that mobile edge. You can use this sample widget as a starting point for own widget projects.
The sample demonstrates:
- How to make a location request and handle the asynchronous result
- How to use the returned location data to display a map showing a location marker
- Handling button input for a simple UI
The screenshots below show the widget running on the Sony Ericsson Xperia X10 mini:
The example uses the Google Static Maps V2 API, which is easy to use and does not require a developer API key. Of course, if you already have a key for a different mapping service you can use that instead.
