Air for Android: Screen Orientation
While developing mobile applications you may want to have your application change and move based on the orientation of the screen based on how the user has oriented their mobile device. This may seem obvious and “default” but there is some programming that goes along with implementing this.
On the highest level you just need to add a stage listener and a tag into the application descriptor – we will look at the exact code.
If you are starting with this post I recommend actually starting with a previous post introducing AIR for Android Development. There is a ANT file there that you will want to have.
Application
Here you will notice that I just listen to the stage for the StageOrientationEvent.ORIENTATION_CHANGE event. When the event fires there are five possible orientations that the stage can be in: default, rotated left, rotated right, upside down, and unknown.

Application Descriptor
If you ran this app without adjusting the application descriptor then the orientation event probably isn’t firing. This can be fixed by adding the following line in the initial window.
<!-- States if the window auto orients to a specific direction (uses the accelerometer) Optional. Default false. -->
<autoOrients>true</autoOrients>
<autoOrients>true</autoOrients>
And the full application descriptor:

This is actually not the best way to listen for orientation change, there’s a couple of issues:
1. You won’t get the event on startup, and orientation shows UNKNOWN. So if you’re depending on this to size your views, you need to add additional code for a startUp check.
2. There’s specific occasions where the orientation event doesn’t fire, can’t remember exactly but I think it’s going from UPSIDE_DOWN to ROTATED_LEFT, or something.
The best way is the simplest, stage.RESIZE. It always fires, even on startup, and never leaves you wondering what orientation you’re in. And of course, if you really need to know, a simple (width > height) check will tell you if you you’re in landscape or not.
Personally I build my views to be totally liquid, so I don’t really care what the orientation is, i just fill the size I have available. But I could see a situation where you might want to show different UI depending on the orientation.
Also, one other benefit to the stage.RESIZE approach is it makes it super easy to test different layouts while in development, I can literally drag the corner of my app around to test how the app responds to different resolutions/aspect ratio’s, without needing to publish to the device at all.
@Shawn Great points. I’m hoping the layout change from upside down to rotated left is just a bug – maybe you have a jira link for that? I personally haven’t seen that rotation issue though in my tests, what device are you using?
I completely agree with making everything flow layout. After years of making just flow layouts, the move to mobile has been much easier. I never really thought in pixels.
I definitely see what you are saying about the resize event. I just added a check into my apps for initial orientation, but you could go off of resize. Great finds!
Ahh I remembered the bug: If you rotate your phone upside down, the stage will re-orient, but you won’t get the orientation event.
According to Joe Ward on the Android Prerelease, the root issue is an Android event dispatching bug. The deviceOrientation property changes, you just don’t get the event.
So, you can either:
1. Use stage resize as your hook, but then look at the deviceOrientation property to size your views.
2. Forget deviceOrientation alltogether, and just use stage.stageWidth and stage.stageHeight (which I think is best, since it end up being super clean, and brings several other benefits)
@Shawn it’s great to know. I have a project right now that I switch out renders and whatnot dependent on orientation. I’ll check out the resize event and see if my app responds better. Thanks for the input.

Hi guys I’m new to mobile development and would like to know where I could learn more about creating liquid layouts and effective orientation changes. I’m going off of
http://www.senocular.com/flash/tutorials/windowmoveandresize/
but would like more android specific info.
Cheers
@Graham
That is a bit more complicated. Using Flex you can use constraints to create liquid layouts. In Flash it is a matter of responding to a stage resize event. Feel free to as a bit more, but this part is hard to just answer directly.

how do u make the app itself load as a landscape app by default.. the stupid simulator always opens as a portrait app! I know there’s a configuration xml to change, but how and where do you find it in Flash Builder 4.6?
@hayesmaker Check out the application descriptor and the
