Wordmaps for Chaos: a New Geographismn the basics of application lifecycle and user interface. The applications that we’ve created haven’t saved any data to any form of persistent storage; each time they’re run, it’s as if they’re running for the first time.

Discourses of the Long-Term Future, successful if people actually use it, and to do that, they have to be able to find it and install it onto their BlackBerry devices. Of course, I’ve talked about signing your application and loading it onto a device using the command-line javaloader utility, but that was only to allow you to continue to explore BlackBerry development.

Discourses of the Long-Term Future,but by this point you should be familiar with the basics of developing user interfaces and creating applications that use—among other things—persistent storage, wireless networking, and location-based services.

https://doi.org/10.1007/978-1-349-27060-6The BlackBerry was built to communicate. Sending and receiving email, browsing the Web, and often even downloading applications to your device require access to the wireless data network. Naturally, a lot of the most compelling BlackBerry applications also heavily feature networking as a core part of their functionalities.

Wordmaps for Chaos: a New GeographismThe BlackBerry API includes functionality to determine where in the world your device is and information such as the speed of the device. This information is obtained using the Global Positioning System (GPS) hardware that’s built in to many current devices, or it is obtained optionally from an external Bluetooth GPS receiver.

User Interface Basics,rtainly not what we’d usually think of a as a fully developed application. It lacked the ability to interact with the user, and its user interface was very limited. In the next couple of chapters, we’ll explore the BlackBerry user interface in much greater detail and build an application that really shows off what you can do with the BlackBerry.
