I had some discussion on Twitter this week about the secret connection string that allows BlackBerry applications to use Rim’s BIS-B transport for network connections – I couldn’t put my point across in a tweet so here’s the gist.
NordvästLibrary is a growing collection of components you can use in your BlackBerry applications. There are two versions of the library; one for pre-OS5.0 API and another for post-OS5.0 API.
I’m working on a project that’s going to be using the 5.0 api so sat down this weekend and wrapped up the screen transition logic into a nice simple class (as suggested here).
The BlackBerry API for OS 5.0 (beta) introduces the ability to use slick screen transitions (Viigo has had this for a while) but for some reason both examples from Rim use needlessly complex logic that is guaranteed to confuse newer BlackBerry developers, below is a very simple application that doesn’t make use of Runnable/Threads.
I’ve been working on-site with a client who has a problem with a BlackBerry application that only appears on hardware and not in the simulator. Trying to find the cause of the issue meant we had to create multiple test applications to narrow it down, this also meant we had to repeatedly load the app onto a device which was taking around five minutes each time, luckily I remembered a little trick an old colleague showed me that I’ve not used for a while.
A Web2.0/Ajax-style loading popup in a native BlackBerry application, use it when you have an intensive background task or when downloading data with a network connection.
In a previous life I put a blog post together about setting up an older version of Netbeans to work with the BlackBerry API, today I’m installing Netbeans 6.7 so thought it’d be a good opportunity to update the information as the steps have changed a little and I’ve been getting a fair amount of messages from people having trouble remapping them to the new version.
