Torch and other old versions compatible problem

Question

I developed an application with simulator 4.6 and 5.0 then a couple of weeks later, today I finished the Torch version of my application (JDE 6.0 and simulator 9800)

My application works great with Torch but for the other older versions I got a

class net.rim.device.api.ui.ScrollView error.

I googled and found some advices like a "try with JDE 5.0 or stg else" but I didn't work.

So how can I solve my problem? Is it possible for a application to works with every model of BlackBerry Device?

Answer 1

You want to use the BlackBerry Preprocessor, and generate a build for each version of BlackBerry OS you support.

Answer 2

The ScrollView is not part of the API before version 6.0.

You will have to use a normal view(Manager) and send in the property to use scroll.

Behaviour A vertical field manager lays out fields top to bottom in a single column. You can build this manager with Manager.HORIZONTAL_SCROLL to accommodate fields wider than the manager's visible frame; you can build this manager with Manager.VERTICAL_SCROLL to accommodate collections of fields taller than the manager's visible frame.
