What Angry Birds Is Using on Series 40 Phones

Rovio's Angry Birds made their entrance to the Series 40 with the Asha lineup of devices announced on Nokia World. If you have missed it Engadget has a post and video that features the mighty eagle showing off Angry Birds on Asha 303.

Angry Birds performs so well on these so called feature phones that it got people puzzled. I guess many people do not expect much from JavaME, therefore there had been questions whether this is actually a JavaME application or did Nokia open up its C libraries, or some other secret API to Angry Birds.

It is a well developed JavaME application! It does not even need access to APIs that are available to manufacturer/operator signed MIDlets. Below is a list of usual suspect APIs that Angry Birds uses as you can see it is a list of APIs that are available to any JavaME developer that targets Series 40.

So people, there is no mystery to Angry Bird's performance on Series 40, It is just an amazingly well developed JavaME application.

Nokia SDK 1.1 for Java available now.

At the NokiaWorld, Nokia announced Asha lineup of devices. There are extremely well built Series 40 devices that are likely to form a big market for developers quickly. Today, we are releasing the Nokia SDK Beta for Java 1.1 so that Java developers can start working on their applications right away.
Nokia SDK for Java 1.1
SDK is based on my favorite of the announced phones, Asha 303. Since the SDK is available today, you can develop and test your applications and be ready when devices are available on your target market.

Testing Support for In-App Purchase in Different Stages
As we are starting to accept applications that use the new in-app purchase functionality on Series 40 Java, we have enhanced the in-app purchase tools on the SDK. The IAP simulator, that was introduced on the earlier 1.0 release, now supports both offline and online testing for in-app purchase applications.

In the offline simulation mode, in-app purchase APIs will simply return the values that you have entered on the simulator to your application. This is particularly useful on the early stages of your development since it will allow you to start testing before even submitting the application to Nokia Store.

The online simulation and the test mode on the device is very similar. In this mode, SDK or the real device will communicate with the back-end servers. No monetary transactions will occur in this mode. It is possible to try out different scenarios such as failure of a purchase with the online simulation as well. The Nokia SDK manual that is installed together with the SDK provides more information on how to enable these modes.

This new emulator also significantly improves the system properties that you can access and simulate during development. All the Nokia system properties that were opened are now available on the SDK. In addition, you can simulate different values for the com.nokia.mid.batterylevel sysyem property and the com.nokia.mid.mnc and com.nokia.mid.countrycode values from the preferences.

The improvements and features are not limited to these, you can find the gory details on the Nokia SDK project. I have been using the SDK for my daily development for a while and it is already good for daily use. and available for download .
