AIR App on iPad retina

Hello,
Juste have a basic question.
I would like to compile with IOS SDK 5 in order to get the full display capacities of an iPad 3 retina. But if I submit this app to the app store, how will devices running on iOS4 will react ?
Do I have to developp 2 apps, one for iOS5 and another one for iOS4 ? Then, how the appstore will make the difference ?
Thanks for any help

You need not develop separate apps for iOS 5 and iOS 4. You need not use the -platformsdk option to package the AIR app to be able to use the full display capabilities of an iPad Retina since AIR 3.3 itslef supports iOS 5.1 SDK. Please find more details here.
Also, you need to set <requestedDisplayResolution> tag in application descriptor to high.

Question about Apple's new iPad retina requirement.

Apple recently made it a requirement that apps support all retina displays for both iPads and iPhones.
What acceptable options are available in AIR for supporting the iPad Retina display and still meet Apple's new requirement?
Here's my situation :
I've been working on a universal app using AIR 3.6 that works well in all iOS resolutions other than for iPad retina (2048x1536).
When building native support for the iPad retina resolution, the app performance is very poor (due to having to animate and manipulate such large bitmaps). The coding approaches that I've used are supposed to be good on performance, so I doubt that I can optimize things to the point where the performance would be acceptable using the larger art assets.
In comparison, when I use an older version of AIR (3.2) and let the iOS compatibility mode automatically scale up the app to fill the 2048x1536 screen, the performace of the app is just fine (and looks almost identical).
Would using this type of approach cause an app to be rejected by Apple now?
It appears that AIR 3.6 added the ability to restrict just the the iPad high resolution (without restricting iPhones ) using :
<requestedDisplayResolution excludeDevices="iPad3">high</requestedDisplayResolution>
It seems that this would solve my performance issue, but I'm not sure if Apple's new "retina support requirement" would result in my AIR app being rejected if I used this approach to disable iPad Retina support.
Does anyone know if Apple will now accept an app that was built with iPad retina support disabled through this approach?
Another option that I've tried that may be a workable solution is :
During launch when 2048x1536 resolution is detected, the app loads all of the 1024x768 art assets instead and then scales up the app by a factor of two (using scaleX = scaleY = 2).
The above seems to generate acceptable performance. The artworks looks a little blurrier and less crisp using this approach due to the scaling, but is acceptable to me personally. As this is technically using "standard" resolution art assets and scaling them up, would taking this approach get rejected by Apple?
I'm open to any other options/approaches/suggestions to adding iPad retina support that would allow me to address the performance issues on iPad retina and still allow my app to get approved by Apple. I'm just a little bit confused on what constitutes an app having "iPad Retina" support. Does the app just need to be compiled with a newer version of the iOS SDK to get through the approval process, or does this mean something else?
Thanks.

Seems like you have two options, if you are already scaling stuff down after launching at a higher res why not make it an option. Have a setting for "High Resolution" and one for "High Performance" the difference would is one would run in Retina mode and one would run in standard mode so users with iPad4 and iPhone5 could probably use the High Res but iphone 4 users can switch to the High Performance setting.
The way I have dealt with it is design everything to a 1024 width and 640 height, this is standard Kindle Fire resolution but almost all devices crop the app in a way where all the key features fit on screen, I just had an app approved 2 days ago by Apple using this technique so basically I am running 1024 graphics on the retina screen, they look great (we are only humans and we can't make out every pixel despite what Apple thinks) and the performance is nice as well. I think they worry about apps being stretched for some reason when apple ups a 1024 app to a retina width using their software it looks horrible but if it is done by the developer it looks great. Download a non retina app and try it on a retina iPad or export your app for Standard resolution and check it out vs exporting for high.
I think you will be fine either way.

Adobe AIR Apps + Safari = Very slow

Hi everybody,
I'm experiencing a strange behaviour of my Adobe AIR Apps on iPad. I've tested several Apps now (one GPU-Heavy Game, one CPU-Blitting App, one pretty standard Puzzle) and all of them do have the same issue - as soon as Safari is running in the background it sometimes (not always.. and most likely on iPad1) slows my App down to 1fps. Until I close Safari again. I haven't ever seen any other App doing so, thus I believe it's an Adobe AIR bug. Maybe only on iPad though.
Does anyone know why this happens or if I can get around of that? Besides my Apps run superfast.
What I've tested so far is:
- My memory usage is ~4mb. Doesn't seem to bother him if it's more or not
- My GPU-Cache is held quite low (but even with empty GPU Cache this issue appears)
- I'm using an Enter-Frame in all my apps which simulates the rendertick. Maybe this may be the fault?!
Many thanks in advance,
Marvin.

Furthermore:
- if the iPad was restarted you can have opened any iOS system-app without slowing down the Adobe AIR app
- nevertheless after some hours this bug occurs again.
Our game is in stores now: http://itunes.apple.com/us/app/ifunnel-frenzy-hd/id457822239?mt=8 and many people send us bugreports because of it. As soon as I'm telling them to close iOS system-apps things work superfine again.
You can download and test this bug for yourself - I think this might be pretty self-explaining then.
I'm a bit struggling how to solve this.. honestly.

Some air ipad apps are ipad 2 only - why?

Im trying to work out what works on the ipad 1 and what doesnt. Clearly some apps say ipad 2 only, but why is this. A game like Machinarium doesnt work on the first ipad - why? What is or isnt supported. Im guessing stage 3d requires ipad 2 or higher but what else? thanks for any help you can give

I'm not worry. I'm developing a new app and obviously the New iPad is covered. It's just another one more screen, nothing more. I'll crop the graphics for two kind of resolutions (to avoid the problem mentioned above):
< 1280x800 (iOS smartphones, iOS iPad 1-2, Android smartphones, Android tablets)
1280x800 <--> 2048x1536 (iPad 3, SMartTVs)
And I'll redraw the images to adapt the graphics to the device

AIR + iPad retina issue

Will the air to iPad retina issue be fix in the flas pro cs6?

Hi guys,
1) I'm currently running a trial copy of CS6, Air 3.2, and I get 'App descriptor cannot parse file' error whenever I try to modify the xml file.
I'm just trying to remove the icon shine, which worked fine in Flash 5.5.
<key>UIPrerenderedIcon</key><true/>]]>
Also, I tried inserting the 144x144 icon, which published ok, but didn't seem to work. And that line of code later disappeared from
the xml.
2) My mac is Snow Leopard, so I take it I have to upgrade to Lion (do I have to buy it, or is it free to developers?!)
If I then get the latest XCode, and target ios 5.1 with Retina display, will my apps still be compatible on devices with iOS 4?
Thanks,
Matt

Will I need to purchase iWork for my iPad if I purchase an iPhone 5s? Everybody knows the iPhone 5s with IOS7 gives iWork for free. Then iWork would be listed as purchased app in my itunes store under my account. My iPad retina is in the same account...

Will I need to purchase iWork for my iPad if I purchase an iPhone 5s? Everybody knows the iPhone 5s with IOS7 gives iWork for free. I assume that if I buy an iPhone 5s (or 5c) then iWork would be listed as a "purchased" app in my itunes store under my account. My iPad retina is in the same account... or are keynote, pages, and numbers completely seperate between ipad and iphone? I know they would be a seperate purchase for my Powerbook. Thanks so much for your help!

Hi,
I was able to load the Productivity Suite / Free !! on both my iPad mini and my iPhone 5s with no problems and at no cost.

HP ePrint mobile app on iPhone 4S & iPad Retina--Both devices say "Photos (0)"

I have just installed HP ePrint mobile app on both my iPhone 4S and my iPad Retina. However, when I go into the app, when the main screen pops up ("Photos" -- "Cloud" -- "Web" -- "Email"), when I tap "Photos," on either device it says: "Photos (0)"--i.e., I'm assuming that the app thinks I have "zero photos" on both devices, which of course is not true. Other details: (1) I have a Photosmart 7510 on my home wireless network; (2) I am able to print OK to the 7510 using Apple "AirPrint"--no problem there; (3) I can also print using either device (iPhone or iPad) using the HP "PrinterControl" app. So, how is it that HP ePrint mobile app cannot "see" my photos on either my iPhone or iPad (especially since they can "see" those photos when using the HP "PrinterControl" app). Thanks very much in advance to anyone who can shed some light on this situation.
This question was solved.
View Solution.

The issue is related to the privacy settings on ios 6. To resolve this go to settings on your device, then you should see a privacy section. In there go to photos and turn the eprint app on. This should work to allow you to see the photos.

2 New Ipads (Retina and Mini)(New to Apple) How do I share purchased apps, but others have each act independently? Mini is for the Wife the Ipad4? is for me. I want to use mine at work, etc. She's home with the kids. Can we set them up seperate, but share

2 New Ipads (Retina and Mini)(New to Apple) How do I share purchased apps, but others have each act independently? Mini is for the Wife the Ipad4? is for me. I want to use mine at work, etc. She's home with the kids. Can we set them up seperate, but share
--break--
So we are entirely new to Apple products. I'm an IT guy, but have always been a windows user.
So the Ipad with Retina Display is to be mine (and will use it at work for notes, organization, etc)
The MINI is for the wife.
But, are we allowed and can we.. buy an app and share that app between both devices? IE. Can I buy a copy of Angry Birds for the House and both Ipad's use that single purchase? and if so, can we still run the Ipads seperate other than to share the apps purchased. IE my facebook and email set up on mine and hers on her ipad mini?
When I finally find a note taking app I like, can I share it on her ipad, without her having all my work files, etc?
Thanks for helping out the apple noob. Hoping for a great experience, and anticipate droping $100 in apps the first day.. just don't want to do that twice. If this is against the usage policy, thats unfortunate but good to know. (I mean we can share stuff on PC as long as its in the same household)
thanks again (explanations or links are fine)

There are a number of Apple services: iMessage, FaceTime, iCloud, Game center, Find My iPad, etc.
Now, to share apps, music and books you need to have the same Apple ID:
iPad's Settings > iTunes & App Stores > Apple ID > Your purchasing Apple ID.
For the other service, your wife should have her own Apple ID.
All she needs is a valid e-mail address, apply Apple ID below:

How do I move apps from iphone5 to new iPad retina?

HOw to transfer apps from iphone5 to new iPad retina?

One way is to sync the iPhone using iTunes on your computer. Then assuming your iPad is using the same Apple ID as your iPhone, sync your iPad using the same iTunes. Make sure you have the apps sync set up correctly in iTunes for your iPad. While the iPad is plugged in to iTunes, go to the Apps tab and check the instructions.

What is the best voice to text app for iPad Air?

I had the app Dragon (a voice to text app), on my iPhone and downloaded it to my iPad Air, but it's not working. Reading the "help" area it says something about ATT iPads don't support it. I have ATT.
But, I can open the app and it reads "Tap and dictate" as though all is fine and dandy and then after practically yelling into almost every part of the iPad (to no avail), it just says " Sorry message not recognized. Please try again."
Can anyone help me on this? Also is there a better/best dictation app for iPad?
Thanks, Joan

You can use text-to-speech in any app. I'm a big fan of the app Drafts as it allows two touch tranfer to any number of other applications, not unlike how I recall Dragon worked. If you don't want to spring for Drafts (though I can't recommend it highly enough!), you can always use the built in Notes app then copy and paste when you're done.
No, you can't see the words as you speak. However, you can always stop after a couple of sentences and review.
Best of luck.

Hello, suffianr78.
Thank you for visiting Apple Support Communities.
If you have the sync photos preference selected in iTunes and photos are still not syncing, I would recommend processing the steps in the article below.

What is better for college? An iPad air or an iPad mini with retina display?

I'm currently a junior in high school and I'll be graduating in the summer of 2015. My parents, well mostly dad, are planning on buying me the iPad air with 128 GB of memory. I got curious and went to look at the price and compare models and I saw that the iPad mini with retina display was the same as the iPad air, the only difference is the size. Since I saw that it was cheaper I was thinking on telling my parents to buy me that instead of the iPad air because it is more costy and my family isn't really the rich kind of people. I will be only using the iPad for school and nothing else since I have my iPod to play games on and stuff so it will only be used for purely educational purposes. Plus I've been hearing around that the iPad air is not that great and stuff because it has a bigger screen and such. Personally for me, I do not care about the screen size I just care about the price for my parents' sake because I don't like it when they have to spend a lot of money. So can you please help me decide on which to get and why it would be better than the other? Please and thank you.
