DPS on iPad1

Hi there,
in our agency, we work with the iPad2. One of our customers has the iPad1 and several performance problems, viewing a magazine.
Are there some known problems with PDS on iPad1?
Don't know what to do...
Thx in advance!

There are no known issues that have to do with feature limitation or sth.
like that.
But, the iPad1 has a slower processor and less memory. So be sure to
downsize all assets you use in interactive overlays, especially image
sequences and slideshows.
I found out that performance incredibly increases on image sequences if you
have images at 100%, instead of letting the ipad downscale them to 33% e.g.

DPS Tips app updated for v19

Apple approved the new version of the DPS Tips app: http://itunes.apple.com/us/app/digital-publishing-suite-tips/id436199090?mt=8
Instead of simply updating the app, which is usually the easiest approach, I recommend that you remove DPS Tips and then install it from the App Store. Re-installing is especially important if you have an iPad 3. A current limitation prevents the high-resolution rendition folios from being available if the library has ever "noticed" the low-resolution folios, even if you haven't downloaded them. This issue should be fixed in one of the upcoming releases. If you're creating renditions for your folios, remember to publish both renditions before you notify users with a push. To be safe, the best approach is to publish the high-resolution rendition first.
The DPS Tips has been approved for the Apple App Store and Android Market, though I haven't updated the Android content. Amazon still hasn't approved the app due to an in-app purchase issue. The Viewer Builder enables every viewer for IAPs, but Amazon recently began rejecting free apps like mine unless you set up IAPs. We're waiting to see if Amazon changes its approval policy or if we need to add an option to the Viewer Builder.
Here are some changes I made to the app:
* I added renditions by using one set of 1024x768 source files. If you have an iPad 3, the cover images in the library should include "2048x1536." If not, remove and re-install the app.
* I divided the old overlays folio into two folios: one basic and one advanced. The advanced folio includes a few new articles and an updated article on pullout tabs. The new pop-up video article includes a rocket launch effect that's so cheesy not even my 8-year-old son liked it. Colin even asked me not to credit him for the video. I might have to revisit that example.
* I added a new article to the Effects folio that includes an HTML5 scratch-off example. It links to a Cookbooks recipe where you can download and repurpose the HTML code.
Here are some folio size stats. For some reason, the PDF files were relatively much larger than what I had seen in my testing.
Folio Basics: iPad1 - 33 MB (PNG) / iPad3 - 47 MB (PDF)
Overlay Basics: iPad1 - 50 MB (PNG) / iPad 3 - 90 MB (PDF)
Advanced Overlays: iPad1 - 41 MB (PNG) / iPad 3 - 85 MB (PDF)
Effects: iPad1 - 5 MB (PNG) / iPad 3 - 7 MB (PNG)
Single Edition: iPad1- 4 MB (PNG) / iPad 3 - 12 MB (PDF)

Hi,
This is very interesting. I'm not an expert but i could do almost all the steps, but i can not do the sign step. i dont know where my release.keystore is. i created a .key.p12 file, is it?
I'm trying to do this for a Galaxy SIII
Thank you

DPS(PDF) on Content Viewer V24 for iPad

Hi all,
I created DPS Magazine Decmber issue (1024 x 768: Image = PDF),
and checked it(not published folo) on Content viewer v24(2.9.0.0.63929) for iPad.
I set Folio version: v22 on Folio Builder menu, because of my released viewer app is v22.
On iPad1, pinch-zoom works well, but text rendering doesn't work.
On iPad2, New iPad, pinch-zoom and text rendering work well.
My DPS Magazine Novermber issue, text rendering also doesn't work on v24 iPad1.
It worked well on v23 iPad1.
Is this a just problem of Content viewer v24(2.9.0.0.63929) for iPad?

I was able to replicate the issue and have reported this as a Bug. I'll update you directly when this is resolved.

Is there any need for a 1536 x 2048 folio anymore? Do they even work with DPS v32?

So I just received a gig from a client to design their new magazine issue using their provided back issue indd DPS files (CS6), along with their new content from the latest print edition that will fill these articles. However, the previous DPS documents were built using 1536 x 2048 pixel (vertical orientation) pages. Is there even a use for this folio size anymore? And would it even work with Apple and Google Play and the latest folio buider?
I recall in 2012, I had to build two renditions during the iPad1 to retina transition, so it could be read on both devices. But I thought Adobe soon abandoned the need for two renditions and went with just the 1024 pixels. I've only worked with 1024 since with all my other clients. Is this correct thinking? Do I need to convert these files to 1024? I'm guessing so, but I don't want to just guess.
The other thing I wonder is if Apple had approved their back issue on 2048 pixels, would it mean a re-submission the new folio using 1024 px height? We have to update the App to iOS 8 anyway, so I just need to be sure I'm working with the folio size.
Can I assume the v32.2 folio builder is solid enough to run with at this time? Hoping one folio will work with both storefronts (google play and Apple) without any glitches/scaling issues.
Cheers,
Brian

I think I'll advise my client to convert their current 2048 pixel folio to 1024 pixel height. Then have that 1024 build approved by Apple. Then push my new issue content into the approved App shell. The only time I needed a 2048 rendition is when the new retina iPads came out (mid-2012), and we wanted to take full advantage of the resolution. We also used a 1024 rendition for the iPad1s.
I suspect their 2048 folio is what is making their App in Content Viewer crash. Also, they didn't have a V or H in the filenames, which is what I was trained to do with naming each of my articles, so perhaps that's what's making it crash? I was surprised it would even upload/recognize an article without the V or H in the filename.
Does this sound like possible solution to fix the crashing? The other thing I noticed is that they didn't package their files with fonts and links for each article like I would (They had 20 indd article docs in one issue folder, then all images for all articles were in one links folder (named images, not links. Another suspect. Does Adobe prefer "Links" for the assets?).
If I could solve their crashing problem, I'd be their rock star.

V27 folio, Appbuilder and iPad1

I did an upgrade to the v28 tools. I build an App, with a v27 folio, but the App can't be downloaded to the iPad1, so I removed InDesign, reinstalled Indesign and the foliotools v27.
After that I can use the Adobe viewer on the iPad1 (after opening each document, change a little thing, and then save (else the articles on the folio are black)).
But when building the developpers App (the single edition way), it won't be installed on the iPad1. Is it possible the Appbuilder (single edition) only makes v28 build? Is it possible to go back to v27?

Best to take a look in the FAQ: Adobe DPS Apps: Impact of iOS5 End of Life with V28
http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/devnet/digitalpublishingsuit e/pdfs/dps-viewer-ios5-eol.pdf
With the upcoming V28 release in mid-‐September 2013, Adobe DPS is dropping support for iOS5. V28 apps will not run on iOS5, and by extension, on iPad1. As a result, publishers that want to continue supporting iPad1 must do the following:
• Continue authoring folios with a target app version that matches (or is less
than) the app version of the existing app on the iPad1.
• Understand that readers using the iPad1 will not be able to install apps built
with V28 (or later) app version.
As part of our steps to stop supporting iOS5 we’d like to answer common questions
about how this will impact the experience for your Readers.

Are there any limitations on the amount of content published using Adobe DPS?

I can not find any information on this and i need to know if there are any as it might pose a problem regarding the publication i am currently looking to make.
Also, why is there no way to contact customer service? I can not find any forms or e-mail adresses to inquire my questions.
Best,
Kim

Bob,
We created .IPA files and it behaves pretty much the same as Content Viewer:
- With the small number of articles (about 30, some having up to 30 pages), it is stable even on iPad1, just a bit slow to render new pages with random browsing.
But once we added more articles (the target is 150+ as this is the size of content we publish), at some point the app started crashing on both iPad1 and iPad3. The same is for the Content Viewer on iOS.
I understand your concern as a reader, regarding lengthy articles (your earlier post in this thread). We created a secondary navigation UI to ensure every page in every article can be reached with no more than 3 taps, so it is supposed to be read in a WebSite-alike fashion.
But, technically speaking, there seems to be a barrier that we are not aware of. This barrier prevents from creating complex and content-rich folios, as good as books created with Apple's iBooks Author. and possibly better.
Given the lack of definite answers on this particular matter, I started to doubt: is Adobe really interested in supporting folks creating publications like multimedia references with this product?
If it appears that DPS/Folio is only suitable for simulating printed glossy magazines and corporate catalogs, than we might have chosen a wrong tool for the job
But I still hope to get helped...
Anyone???

DPS Enterprise License for Apple's B2B Store

Hey everyone,
we developed an app and successfully tested it on our iPads via DPS. We aim to distribute the app via the B2B store from Apple and the tutorial PDF from Adobe tells me that we need an "Enterprise license" for DPS.
Our company uses Adobe Creative Cloud and I am wondering now whether this already means that we have an "Enterprise license" for DPS, as well?
Cheers,
Alex

No. It does not.

Is there a way of making the Edge Commons parallax effect work smoothly with DPS on the iPad?

I want to create a feature for an iPad magazine utilising the parallax effect shown here...
Parallax Scrolling Made Easy (Adobe Edge Animate Online Week, Episode 9) - YouTube
I am using Digital Publishing Suite to publish to an iPad. I ran a test and the effect partially works, but not smoothly.
As you scroll down the animation does not play. Once you finish scrolling the animation then jumps to whichever point has been reached on the timeline, rather than animating as you scroll down the page.
Is there a way to get the same animation effect through DPS that you see in the browser? Or is it not compatible?
Thanks!

As lllaass said, you can't.
If you want Apple to add backgrounds to the iPad version, leave them feedback: http://apple.com/feedback/ipad.html.

Since updating to iOS5, iPad1 is no longer recognized by iTunes!

Hey there! I know there have been many variations on this question in the forums, but I have not come across anything that could help so far.
I updated the iPad1 to iOS5 this Saturday. Afterwards, none of the music had transferred over, but as far as I could tell everything else was t here. Left it, & went to bed.
The next day, there were an extremely small amount of apps left on the device (though a few of the purchased ones are there).
From that point on, I have not been able to Sync the iPad. iTunes will no longer recognize/acknowledge it as being plugged in, though the laptop itself sees it and allows me to access parts of it like storage. [My computer, btw, is a laptop - a Toshiba Satellite]. I've tried rebooting the laptop and the iPad (the old press-&-hold-the-2-buttons-at-once trick). I've checked firewall settings. I've scoured the message boards for something that might help, but so far to no avail.
Any clue what else I can do?? Thanks!!!

As your question relates to the iPhone and/or iTunes and not iSync, I would suggest posting in one of the iPhone or iTunes forums:

I keep getting an MTP USB Device Failed error message when I plug in my USB cable into my Ipad1. Can someone help?

This is NOT resolved. The "Upper..."Key in the registry editor doesn't exist as you can see below in the image I am providing. This is still an OUTSTANDING issue, can someone please help with resolving this issue, super frustrating.
This is not just an iPAD issue, I get the same problem with my iPhone as well, both (iPhone and iPad) have the latest iOS 6.1.3 installed as well.

There any way to re-sign the app developed with Adobe DPS?

Hi Everyone , I explain a problem that I have with DPS Single Edition ( it useful that is until May ) to see if anyone knows a solution. I have developed an app for a client , but the client wants to publish the app in Apple Developer with your name . How to export the .ipa or .zip Dps asks certificates Apple account and logically put mine ... (customer is a large company and I do not give me your passwords Apple etc ) you know if there any way they can re-sign the app ? As you do when you develop an app for a client who wants to publish on their own?

Ok they'll ask my client to send me those files.
With notifications no problem because the app does not.
With respect to Itunes connect and publication in the AppStore, will my client who is responsible for publishing the app, complete data etc. from their own.
Your help has been very helpful to me.

Sending Push Notifications with Adobe DPS

Question.
I'm testing out all the Adobe DPS and Apple options. And one of the things I would like to test is Push Notifications.
I followed the iPad publishing guide to be able to get all the certificates so that's ok. Then I was looking for a way to send
push notifications. Because Adobe DPS doesn't really have a UI environment (PLEASE correct me if I'm wrong ;-) to send push
notifications I have to do it 'by hand'. When I tested my app on my iPad I got the "app name wants to send you push notifications",
so i'm sure my certificates are working. Now I just need to send a push message.
So I followed this great tutorial:
http://www.raywenderlich.com/3443/apple-push-notification-services-tutorial-part-12
I was able to do everything and was able to send a push notification ... but I never received it. And the reason for this is because
I don't have the app device token, which is a 64 character serial number which acts as your app address. So I don't have any way of sending the notification
to my particular app. (which is a test sideload multifolio app).
Because the Adobe DPS is cloud based you don't get any code (which I love). But I think that is currently stopping me
from finding out my device token.
What I'm asking:
- Does this mean I can't send any push notifications to Adobe DPS created apps?
- If this is supported somehow, I suppose (again, correct me) I need the app device token for the created app. Where do I get this?
Thanks !

At this time, it's not possible to manually push notifications. When you enable push, only publishing a new folio displays the red badge. At some point, when third-party push is supported, manual pushes will be possible.

Can you move a magazine app designed by another company to Adobe DPS?

My company had a digital company (who shall remain nameless) produce their magazine app under the (digital company's) information. I want to transfer everything over to Adobe DPS because frankly, this digital company did not live up to their promises, have terrible customer service, and are strictly just adding buttons to a pdf (not interactive at all). With that said, do I need to start from scratch and build a new app? Or can I just obtain the app that's already been created? If not, do I just tell the other company to delete our app? Thanks!

If you move to DPS you'll wind up building a new application using our tools and submitting that to Apple as an update to the existing application. Your readers will see an update to the app and when they download it they'll have the new version.
What is more complicated to sort out is whether readers would still be entitled to content they'd previously purchased. That depends a lot on you previous setup, how the previous product handled purchases, etc.
