Is AIR4 compatible with iPad1?

[ArmandN]

I can't seem to be able to install my app compiled with AIR4 on iPad1 (iOS 5). It works on iPad3 (iOS7).

I have both devices with provisioning profiles but when I try to install with iTunes, I get a not helpful error "MyApp failed to install"

Last time I compiled and tested on iPad1 was with AIR3.7

Is this a known issue?

See here:

The requirements for iOS has been increased to 6.1.

Interesting that iPhone3GS seems to be excluded from the iOS devices list too. I was trying to work out the best way of excluding that device (as performance is not perfect on that device for an app I'm currently working on).

[Colin Holgate]

Yes, that’s a shame in a way. Apps generally are ok on 3gs, and updates using AIR 4.0 will no longer work on 3gs, because I think it is limited to iOS 6.0.4.

I’ll explain that to my colleagues and clients!

Hello Everyone,

That's correct,  the system requirements have been updated with AIR 4.0. Technically, it's still possible to run the AIR applications on lower OS versions, however the bugs which are specific to the lower OS versions do get the lower priority now.

Thanks

Thanks Colin. It was silly of me, I should have checked the system requirements but for some reason I was pretty sure Adobe will not drop compatibility with older devices. Makes sense though.

Hi Armand,

For what it's worth, I haven't had issues so far installing and running one of my AIR 4.0 apps onto an iPad1 with iOS 5.1.1, confirming what Pahup is saying.

Notes:

• Installing the *.ipa via iTunes worked for me, as well as doing it via the command line ( adt -installApp -platform ios -package yourApp.ipa ).  So, I am not sure why you couldn't install your app.

• Another detail for compatibility's sake, if you are using Stage3D: the max texture size on older iOS devices is 1024 ( 2048 doesn't seem to work on iPad1, as far as I could tell ).

Cheers.

How does this affect existing apps on the app store that you want to update?  If you compile an update with AIR 4 will the application loader not allow you to upload or does it understand that it is an update for a subset of devices?  Does this mean we have to keep two versions of AIR available - one for updating existing apps and one for creating new apps with?

[Colin Holgate]

Have you tried those builds with the current version of AIR 4, or the next version (the one that is built for iOS 7)?

[Colin Holgate]

You are able to set the minimum OS version in the app descriptor XML. I must try setting that and then do a test to iPad 1 and 3gs, see what happens. Without setting that the current AIR 4.0 does build to those two ok, we’ll see next week if the iOS 7 build version still works.

One worry is that you could make an app that you can build and test onto your own devices, but if iOS 6.1 is forced into the IPA that gets submitted, then customers on earlier systems won’t be shown the app in the store.

Just to clarify, 2048 sized textures do work fine on iPad1 with Stage3D, not sure what settings or code environment you tested on.
