I have a webapp that I created well over a year ago, and running on iOS 6, it's been rock solid. It's designed to work offline and online, from the same home screen icon. I've got a manifest file that loads up the bootstrap javascript, all the js includes, and the core files. The app is designed to store data while offline (using SQLite) then transfer anything in the offline queue to a MySQL database once online. And again, all this was working on iOS 6 with absolutely no changes whatsoever to any of the files, the manifest, etc. for months.
Then I upgraded to iOS 7.
Now I have a host of problems, but they all seem to revolve around database issues. I'm getting a lot of code 6 errors in Chrome (in Safari, I get nothing, just a blank screen). In my reading up on this I found that Apple did make some sort of change to how SQLite runs, but not being an xcode developer I don't have access to the materials on Apple's site, and since I'm not running xcode in any case I don't know if that even applies to my purely HTML app.
My question, then, is this: with whatever changes Apple made on the app side, is there anything that would have affected the functionality of a pure HTML5/JS/SQLite offline web app, bookmarked to the home page via Safari?
IOS 7 limit browser DB size from 50MB to 5MB , is that the reason ? Also I met a end user turn on Private Browsing in their IPAD , also could cause this trouble, hope that helps.
you can check this :http://www.mobilexweb.com/blog/safari-ios7-html5-problems-apis-review
I figgured it out.When you enter safari, a little button on the top left on the keyboard says "private", click it to disable it. The database will work fine. But! jquery mobile will not be able to use the back button. For this, you have to delete appcache from your code. jquerymobile 1.4 will fix this, but for now you will have to live without appcache!

I am working on a simple mobile web app and I am having trouble logging in...
I followed this little sample on making a custom login: http://blog.benmcmahen.com/post/41741539120/building-a-customized-accounts-ui-for-meteor
Nothing too tricky here.
So I run my meteor server locally. On my computer, through the browser, I can log in and create accounts -- no problem.
When I go to my local IP from my iPhone, the website successfully loads but for some reason I am not able to login or create accounts.
I have noticed that for Meteor.loginWithPassword and Meteor.createUser, the callback function NEVER gets called. I have {{loggingIn}} rendering a loading screen and the loading screen is only there for a fraction of a second before the form is reloaded. No errors are thrown (validation passes and the callback function doesnt fail).
Out of suspicion, I deployed the app and tried accessing the deployed website from my phone and the same issue persists...
Any ideas what I cannot log in or create accounts on my iPhone, but I can on my computer? Maybe its a cookies thing? Any ways of solving this?
Thanks a lot,
Chet
Edit:
This works on both my desktop browser and iPhone simulator. Just not my iPhone. Could it just be a local network issue? -- No, even if I deploy the website, I have the same issues...
Also, check out my github post about recreating the issue:
https://github.com/ccorcos/meteorPasswordMobileError
Check to make sure that you are running the same version of iOS on all the devices you are testing on. I have seen iOS 7 misbehave when using Meteor apps. iOS 6 works just fine.
By some mysterious reasons I got myself a jailbroken iPhone 3GS from a vendor whom I am finding difficult to track.
My task is to test out in app purchase functionality on it.
Currently it has iOS 5.0.1 with cydia installed.
No, it does not have Appsync.
I am installing my build through testflightapp API which works without issues with my app so far.
However when I initiate in app purchase, I don't get anything in response.products so far.
I have added productIDs and all in itunes-connect already, checked twice that they are fine, since 48 hours.
I tried testing with iPhone simulator 5.1, but all I got was no values from storekit. I would love to hear if there is any workaround with simulator.
Worked around this finally - deleted my app from itunes connect, re-added it.
It complained about name being already used.
I changed the language of name. And it worked.
Maybe, my prior app setup was right, but I had something else messed up.
In between, I rejected my app. That maybe one of the reason behind this issue.
Lesson?
Don't developer reject your app.
I'm a C++ programmer, but I'm a newbie in Flex. I'm developing a Flex 3 application for a social network using the FlashDevelop. For debugging I'm using the stand-alone FlashPlayer (10.3 debug) downloaded from Adobe. The application is a simple audio player which shows artist/album images.
The application worked properly on both local computer and remote server until I made some layout changes in Main.mxml. I added some HBoxes and changed Image placement. After that the application still works on my local computer, but it doesn't work properly after I upload it to a server.
Application buttons are not highlighted on over/out/click events, images loaded from the Internet are not displayed, text changed dynamically is not displayed, but when I click buttons a sound file is loaded from the internet and starts playing. It looks like some events which are responsible for components displaying are not dispatched, because some part of functionality not related to displaying still works.
To make sure that this is not a server problem, I rolled back to the previous revision. All works fine.
I suppose that this is a known issue, but I have no idea what is the reason.
Could anyone please help me to resolve the issue?
Thanks.
UDP: I observed the issue in IE and FF, I didn't test Opera and Chrome.
Are you tying to access the pixel data of the images in the new version? If so, that might be the problem, as pixel data for loaded images is not (always) accessible so that might throw a security error, which in turns breaks the rest of the interface.
Also, did you try running the remote version in the debugger? If so, is there any exception being thrown?
And no, it's not a known issue, it's the kind of annoying and hard to debug error that you sometime get when using the Flex SDK.
I've created a BlackBerry webworks application that consists of multiple pages each loading data from a local SQLite database.
The application works fine until I've navigated between a certain number of pages, at which time the application shows a blank alert box and hangs on the loading screen that shows between pages.
This is using the Bold 9700 simulator but also occurs on the device itself. I've tried disabling caching, as well as increasing the size of the cache, both to no avail. The console shows nothing, neither does the event log on the simulator.
Has anyone come across this behaviour before? More importantly, how do I get any useful debug information out of the simulator so I can track down the culprit?
Many thanks!
Edit: I've tracked this down the the html5_init.js library that Blackberry recommend for translating HTML5 to Google Gears calls for OS5. Any ideas?
Further Edit: I've removed all traces of html5_init.js and instead I'm using the Google Gears API directly. This resolves the problem but requires that I double up all my database code. Google Gears requires that you call clear() on all ResultSets so that they don't cause a memory leak but html5_init doesn't offer that functionality. Maybe that could be the cause?
Allope,
I've recently bough Flex Builder 3 and I am completely dissatisfied with its reluctance to debug. It manages to debug a few times, but after that, it just doesn't want to "connect to the debugger".
Help?
There is no easy fix for this. You now have to join the rest of us waiting for Adobe to update Flex Builder with a fix they say they have.
You can find the long sad story here: http://bugs.adobe.com/jira/browse/FB-16153:
Basically, this is an issue that has been around for months. Adobe says it has a fix - however - they've not released that fix yet. Adobe reports it's a threading issue...
For the rest of us (waiting for this) - if you need to move forward you can:
A) Live with the problem (painful)
1) Note that in the bug text there are several attempts to work around this - sometimes people find ways to soften the issue - but no one reports a full fix
2) Note that people trying the LocalHost fix - sometimes report a gain in productivity - but in most cases they do not.
B) Switch SDKs from 3.2 (or 3.3) to 3.1 ---- No one knows why - but it fixes the problem (you can then include the SWFs you need for 3.2 directly
C) Develop on Mac [Not a smart ass answer - honestly - for whatever reason this bug is not on Flex Builder for the Mac]
Join the bug discussion - on Adobe's site - it's still active as people are still waiting for the fix.
Make sure you have the required Flash Debug Player.
http://www.adobe.com/support/flashplayer/downloads.html
If that doesn't help, you might have to re-install Flex Builder.
Are you running it on windows vista? It may be this issue:
http://blogs.msdn.com/expression/archive/2009/03/16/page-cannot-be-found-issue-when-previewing-via-expression-blend.aspx
The page is about silverlight, but I ran into the same issue a while back with the flex debugger, and had to add the following to my host file (which windows defender removed):
127.0.0.1 localhost
This is expanded more upon here:
http://circstar.com/FlashLabUnderground/?p=64
I've had similar problems but every-time it refuses to connect to the debugger i have justed downloaded and reinstalled the flash debugger and it works fine. It's a pain but until adobe do anything what can we do?
Have you the tried FlashDeveloper ide? you can build flex project with it and it quite frankly alot better than flex builder for code writing (not ui work).
Hope this helps
Jon
I'm not sure if you have the same symptoms, but I came across a similar problem on one of our development machines after installing Flex Builder 3. When trying to run our app in debug mode, flex builder took a long time to launch the app and eventually timed out, displaying some message about not being able to connect to the debugger.
I found this solution which worked a treat. While Flex Builder is trying to launch the app:
Go to the browser page containing your app/swf, right-click on the swf to bring up the flash context menu.
Select Debugger
Select Other Machine
Enter 127.0.0.1 in the text field
Click Connect and hopefully it works.
NB: If Flex Builder tried to launch the app in Firefox, the page never appeared. It was only when it launched in Safari that I was able to access the browser page and the flash context menu.
