Hey guys, this was my first blackberry application and I learnt a lot while developing the app. The app connects to a PHP file located on a web server, receives response from the server in json format and displays the formatted response to the user.
Anyway, the app makes use of a custom UI, webIcon and other stuffs like that. I hope you guys that build native blackberry apps may find the code useful and may want to develop something nice with it.
The app can be downloaded here http://download.9jawap.net and its also available at Blackberry Appworld.
Here are some of the things you may learn from the code.
- How to create custom screens, textboxes buttons
- How to create blackberry menus, alert boxes
- using json in blackberry jdk
- retrieving device blackberry PIN
- using net.rim.device.api.ui.container.HorizontalFieldManager
- creating a webIcon
- using blackberry tableLayout
- using net.rim.device.api.system.Bitmap, paint,etc
- using com.blackberry.toolkit.ui.container.NegativeMarginVerticalFieldManager
- using UiApplication.getEventLock(), running multiple background processes
- encoding URL strings
- Threading
- updating your application / searching for updates
and more…
As I said before, its the first version of the app, the current version is 1.4, so a lot of changes has been made to the app.
Please comment below or ask a question if you have any issues with the code. Note: Blackberry JDK plugin for Eclipse was used to develop the app.
Hope you guys find it useful.
