Run Tracker is a simple Java ME app that allows to track and record various parameters of running activities, including route, distance, duration and speed of each run.

The complete source code is available, and shows how to use some of the Java ME Location API features to integrate Ovi Maps mapping and positioning features in a MIDlet.

Check it out, and let me know your thoughts about it.

When displaying a map in a Java ME application, it can be useful to be able to intercept events generated by the interaction of the user with the map itself, and the MapComponent and EventListener interfaces give complete support for keyboard and touch-based events.

Check out the full article, showing how touch events can be used to add markers to a map, and let me know your comments: Handling map events with Java ME Location API.

The MapProvider and MapUrlProvider abstract classes are used to provide the data needed to display custom map tiles, that can be used to replace the default map tiles, or displayed above those one, so creating overlay map levels.

When using the MapUrlProvider class, the only needed information that the class must provide is the URL of each tile, that will be used by the class itself to retrieve and create the associated Image object.

The article published on the Nokia Developer Wiki, with both client and server code, shows a possible usage of the MapUrlProvider class to create an overlay level over a map: Implementing a custom MapUrlProvider overlay with Java ME Location API.

PositioningManager, together with the PositionListener interface, allow to get asynchronous and periodical updates about the user’s position, and so allowing to build location-based services in a simple and effective way.

The new article published on Nokia Developer Wiki explores the main features of PositioningManager, and shows how to build a simple service that detect and draw the user’s movements on Ovi Maps: Using the PositioningManager from Java ME Location API.

While the previous two articles focused on the MapCanvas object, showing how it can be used to show a map on a classical LCDUI Canvas screen, today’s article shows how to build a custom map Form Item, extending the CustomItem class, so allowing to show and interact with a map on a classical LCDUI Form screen.

The article, with complete source code and downloadable MIDlet, is available here: Creating a custom Map Item with Java ME Location API.

This new article covers the main aspects involved in calculating and showing a route on a map, by allowing the user to navigate through the maneuvers of the calculated route.

The full article with source code and a downloadable MIDlet is available on Nokia Developer Wiki: How to calculate and show a route with Java ME Location API.

I’ve recently started to publish a set of articles on Nokia Developer Wiki that show the various features of the API in action. You can read the first one here: Geocoding an address with Java ME Location API.

Check it out and let me know your comments.

You can read all the details, download the library together with sample code, and read the full JavaDocs here: MidMaps – J2ME Google Maps library.

This article updates the existing Forum Nokia document MIDP: Using Cable Connection In Nokia Devices. The document explains how to use CommConnection over cable in Nokia devices. There are differences in devices and their port numbers, and also on PC side. In practice using USB connection between PC and mobile device might need some testing.

The same article also shows how to use the Location API from Web Runtime Platform Services to retrieve your current location, and then using this data to get the appropriate map from Google Maps.

You can read the full article here: Static GoogleMaps API in JavaScript.
