At the first Series 40 UI clinic, held on 29 January 2013, Jan Krebber answered developers’ questions about UI design and UX on full-touch Series 40 phones. To start the session, however, Jan provided a presentation based around questions he had been asked about full-touch UI layouts in Series 40.

In this presentation Jan covers three main topics: first impressions, forms, and the UX resources offering on Nokia Developer.

This video presents a 3D maze game developed for Series 40 full touch phones. The application demonstrates the use of Mobile 3D Graphics API (JSR-184) for rendering 3D graphics, pinch and double tap gestures for zooming, and accelerometer sensor for game controls. The concept of the game is classic and simple: guide the marble through the maze by tilting the phone until the time runs out.

Graphics scalability approaches for Series 40 Java ME apps by jaaura

This week’s featured article talks about gfx scalability for Series 40 Java ME apps.

Pixel-mixing-160.pngSeries 40 devices come in a number of different display resolutions, and may also support both portrait and landscape modes. This can pose compatibility, performance and resource problems for app developers unless handled with care. Luckily there are ways to overcome that complexity effectively, while still providing an optimised experience for each resolution and orientation.

This article lists a number of techniques for graphics scalability and points to the Series 40 Java ME examples utilising those techniques. Typically a combination of approaches is used; the best approach depends on the type of app in question.

2537-e90da87212966995003ab4b881778c59In-application Purchase Product Catalog shows the use of IAP with multiple DRM protected items for Series 40 applications. This example is based on LCDUI Form, and demonstrates:

 

  1. How to purchase DRM protected items from Nokia Store.
  2. How to purchase multiple items within one application.
  3. How to design with minimal amount of code.
  4. Easy and re-usable code for user interface.

Find out how to get started with 2D game development for Nokia Series 40 Asha phones, even if you’ve never developed a game. Michael Samarin from Futurice explains how to use the Game Builder tool to create simple games. All you need is familiarity with Java™ technology, with the NetBeans IDE (for which Game Builder is a plug-in), and with the Nokia SDK for Java™. Using the Game Builder visual tool and studying the code generated are great ways to build game-development skills.

The webinar also provides an overview of Java ME classes typically used in game development. Finally, it examines asset-management techniques and associated platform limitations and capabilities.

This webinar video introduces the sensors embedded in Nokia Asha phones and explains how to use them in Java™ ME apps and games.

The structure and usage of the Mobile Sensor API (JSR-256) on Series 40 phones are covered in the video. Attila Csipa, technology wizard at Nokia in Tampere, Finland, supplies a short overview that is followed by examples and coding demos. He uses the Nokia IDE for Java™ ME (Eclipse-based) to show you how to build your code. He also shares best practices and user-experience recommendations based on the most common use cases.
