Super quick post… I’ve created a simple LayoutHelper for Josh Tynjala’s FoxholeControls.
This will help simple containers lay out their components without having to do a ton of custom property/member inspection for each child you want to lay out!
Another quick one comin at ya!
When working on porting over my very first foray into Flex, my Flex particle engine, to the more current Flex4.6 for mobile purposes, I realized I wasn’t getting key events or change events from a debug Spark TextInput!
This is a short post, in which I show how to set a common background for your Flex Mobile Application.
In Flex 3, there was a backgroundImage style property, but in Flex 4 things have drastically changed. Often times, this means you need to re-skin things in order to achieve your goals.
I recently was tasked to get part of an older Flex 3 application onto an iPad. Why not, right? I mean, FlashBuilder 4.5.1 and AIR 3.0 are awesome… This should be cake, right?
There’s a lil gotcha – Flex 3, or MX components, ooorrr Halo components, are not exactly welcomed on Mobile.
Fret not! I’ve figured out the task, and it’s rather simple. (more…)
While doing mobile development, one of the most frustrating things has been form input.
If you’ve looked at any Playbook development, you’ll see QNX has something called ReturnKeyType specifically for this reason.
Being as stubborn as I am, I wanted a plain Flex approach at accomplishing what I wanted, and not to use the QNX library.
Most of this actually is related to Mobile development with AIR, considering there isn’t a bunch of desktop development focus in the SDK.
Adobe released an early version of Flex 4.5 (Flex Her0) just before Adobe MAX last year, and tons of people grabbed it and started writing mobile apps with it.
Since then, quite a bit has changed both in common functionality, and under-the-hood things like List scrolling.
I couldn’t find any clear documentation about migrating your applications, so I figured I’d try to throw together as much information as I could think of.
I will be updating this frequently as I find more changes or caveats while converting my apps, or from what I hear from others.
As Flex 4 (and in this case particularly Hero [v4.5]) works its way into the public, we continue to see components that aren’t there yet. Sometimes they do exist, but haven’t been optimized for mobile (this also has some ambiguity as to what that fully entails).
In the interim, we have to fend for ourselves and build custom components… Well, that’s not always all that fun, but also not always that bad!
I’ve done the dirty work, and created a MobileNumericStepper, as well as a MobileLabelStepper as a parent to it.
There’s a few good use-cases for serialization; for me the first and foremost is the performance combined with ease of use.
In AIR we have SQLite access, or in a bad case we can write some format to a file and recover it later somehow via parsing. But why? That’s a lot of work… And it’s not the fastest approach either.
And what about if we’re doing a browser application that we want to save a state of something, but don’t want to host the storage and write a web service to handle data?
We don’t have stealth access to the filesystem directly, which makes it hard (errr, impossible) to silently store things on behalf of the user.
We can actually tackle both easily using serialization.
I was playing with the Geolocation API, and have been having the hardest time getting it working. It would activate the GPS on my device (a Droid2), but would never trigger any updates and hit my breakpoint.
I knew this had to be something I was doing, because I’ve seen it working, have examples of working source, and can’t get it to work on my device…
