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.

With version 0.3.5 it’s now possible to manually set the preferred timezone from the application Settings screen. To do so, you have 2 choices:

• If you want to use the timezone sent by Google Calendar server, you can set to “Yes” the “Use server timezone?” option
• If you want to explicitly set your timezone, then set the previous option to “No“, and then specify your timezone offset in the “Timezone” field

If you have problems with timezone in your GCal client, then you should definitely update. Just update from within GCal (“Options” -> “More..” -> “Check updates”), or download version 0.3.5 from here:

• Wrong saving of “All day” events
• Wrong time of events saved on device calendar
• Various other unhandled Exceptions that were causing crashes of the application

In this release, a first support for previous Nokia Series60 editions (specifically: 1st and 2nd editions) has also been added, so you should now be able to use Gcal on your beloved Nokia 6600

And, for those who still experience problems, more meaningful error messages have been set, so that it’ll be easier to spot out and solve the issues. So, when reporting a problem, please also add the exact error message you get in the related error popup. Thanks!
