10 Tips for BlackBerry Development

Over time I've gathered up some nice tips I think would help get someone started developing applications for the BlackBerry so I decided to pull some of the more interesting ones together into the following list.

  1. The Eclipse plugin makes life much easier so use it. If you are used to Intellij IDEA then try out the Intellij IDEA keymap for Eclipse
  2. Some information about signing keys:
    • You don't have to get signing keys to make a deployable application
    • They are inexpensive
    • If you do get the signing keys you will have access to libraries that you otherwise can't use
    • You will need the JDE installed even if you have the Eclipse plugin installed as explained here
  3. When sending apps to the background:
  4. Install the MDS emulator. You need the MDS emulator if you plan to do anything that requires a network connection.
  5. If you need SOAP support use kSOAP. There is a good DDJ article with examples on how to use kSOAP in a mobile setting.
  6. Use Display.getWidth() to make your custom items look correct on any device. Keep the following in mind:
    • Make any static graphics you use that need to span an entire screen as large as the largest device size
    • I have created a list of BlackBerry device screen sizes
  7. The BlackBerry has an embeddable browser. There is a good example post on how to use it.
  8. Spend time to make a splash screen. The knowledge base has a good article on making a splash screen.
  9. Make good looking icons and make sure to also define the rollover icon.
  10. If you need charts in your application take advantage of the device always being connected to the internet and give Google Charts a try.

How to create iPhone wireframes with Inkscape

While developing ideas for iPhone applications I've played around with just using Interface Builder to stub things out. This works reasonably well but I know how to use Interface Builder so that makes a difference. If you are designing an application and want to stick with graphical tools only you are in luck because Yahoo has produced a set of wireframing SVG stencils for the iPhone that are very nice.
