Our BlackBerry application is built using BlackBerry software version 4.5. Unfortunately this means that we can not handle touch events, since they are only supported from version 4.7. Since most of our users have 4.5 or 4.6 this is not an option. Up til now the application has had very limited functionality on touch devices like BlackBerry Storm, running in the so called *compatibility mode' with the virtual keyboard displayed all the time and only about half the screen available for our application.
But now we have made a few changes:
We upgraded the Storm device software (to version 4.7.0.181). This solved the problem with the virtual keyboard, which now can be displayed only when needed.
We revised our application. The main problem is our custom object, which did not work well. This seems to be because the navigationMovement method is not called on a touch device. Since we had some application logic in this method in our custom object, it did not work well. The solution was to move the code to the moveFocus mthod, which is called both on touch and keyborad devices.
In the long run we probably will have to provide different installations for users with 4.5/4.6 or 4.7 software version. Still we do not support more advanced touch screen usage.
