Example: Creating a weather forecast MIDlet with in-app advertising support

This example shows you how to create a simple location-aware weather forecast MIDlet that also supports in-app advertising. The MIDlet shows a four-day forecast with temperatures, relative humidity, wind speed, and wind direction. The MIDlet retrieves the weather forecast information based on the device's current location, which the MIDlet determines using either cell ID or GPS positioning. The user can also explicitly specify the location for which to retrieve the weather forecast information. The MIDlet uses World Weather Online APIs for retrieving both weather data and location search data, and the org.json.me library for parsing the JavaScript Object Notation (JSON) values returned by the World Weather Online APIs. In addition, the MIDlet employs in-app advertising in the form of banners and full-screen ads.

In short, this example demonstrates how to:

• Use the Location API for cell ID and GPS positioning

• Use World Weather Online APIs for retrieving weather and location search data

• Parse JSON values

• Implement in-app advertising

The MIDlet has been designed to work especially on various Series 40 devices with different form factors and input methods.
