I made an app, just pages nothing special with app framework, i run the app on my device it is running ok, but when i "pause" my app and then return to it i am getting a white screen, i can remove it only if i tap the screen. Keep in mind that i downloaded app preview from google play and i am getting the same white screen.
Could someone help? Thank you!
Edited:
i found out that the issue is not caused by the android build, but it has to do with the files inside www\app_framework\2.1\
first i was searching and editing all the #fff and i found out that the line inside
www\app_framework\2.1\css\af.ui.min.js
-ms-viewport{width:device-width}#afui{background:#fff;color:#53575E}
it is the white background that we see when we open the app framework, so i edited the af.ui.min.js and i added the background: to green, (keep in mind that i have an image background inside the xdk) i build it i installed on my device and then the issue with the tap white screen turned into the same issue but now the screen that i have to tap is green ! it's like something is forcing the app framework to have the white backgound (the one we see when we open the app framework), i can't remove the white background and i can't make it transparent i deleted the background:#fff but i still got the same white/green or any color i make that line above.
After that i deleted all files that are inside www\app_framework\2.1\ and i built the app, yes everything was broken but my main thought was to see if i would have to tap the screen again, and in the end i got no white screen!
So there is something wrong inside the www\app_framework\2.1\ !
I had the same problem, just in case someone has a similar problem, this is how I dealt with it.
Ensure you have a very good internet connection, if the connection is poor, most likely the intel XDK will have problems uploading or downloading your app completely.
You can opt to download your built app from your INTEL registered email - they always mail you a link to your built app - instead of downloading it via the XDK.
Try deleting previous app build in your INTEL XDK server, go to https://appcenter.html5tools-software.intel.com/csd/ControlPanel.aspx to see a list of your uploaded INTEL XDK app. After deleting do a fresh build.
Avoid editing your source code as the Intel XDK is uploading your app.
Cheers, enjoy your coding ;)

I have a problem with a custom splash screen. This is an iphone-only app (meaning it's targeting only iphone in the tiapp.xml), running in the iPad simulator sdk 3.3.0, ios7.1 and Alloy.
The app should run in compatibility mode, the problem is that even though I have all resources inside my assets/ folder, the standard Appcelerator's splash screen briefly appears before the simulator switches to my custom one.
here's the folder structure:
And here's the sequence of images when the app is loaded:
From the last pic, We can still see the appcelerator's icon, so I'm guessing Titanium is loading my custom image on top of the standard one?
Could this be a bug? I figured if Titanium CAN find my img, then it isn't a problem on my end?
The weirdest thing is that I've looked in all folders for this default Appcelerator picture and couldn't find it. I've also tried a clean build & manually deleting the build and Resources generated folders.
Thanks for all the help, this is driving me nuts!
I got this to work after manually deleting the app from the Simulator's system before running the project.
I'm not sure why, but it seems that the simulator somehow 'caches' the last img, and maybe it had this old img of my splash.
Our company has an app which is basically an eBook reader.
We use the RMSDK to perform book downloads & read.
Now, something very strange is happening in iOS7 devices (not in the simulator):
I download a book using the fulfillment method in the RMSDK
I wait for the book to finish downloading. The book is saved in the NSCachesDirectory (for App Store guidelines reasons) - so far, everything works fine
I hit the home button, the app moves to the background
I hit the app button to bring the app back, that's when the problem happens:
The app gets completely stuck. Hitting the home button does nothing, hitting the power button shuts down the screen, but then hitting the power button again does nothing.
The device itself has effectively crashed.
After a few minutes, the Apple logo appears on the device and the device comes back to life after a reboot.
I have no idea what in my code could be causing the device to act this way. Shouldn't the iOS7 sandbox prevent me from being able to crash the whole device?
Any ideas on why this could be happening and what I can do to prevent it would be greatly appreciated.
EDIT:
I placed a breakpoint on the -(void)applicationDidBecomeAcvive: method in the AppDelegate, and it's not being called when clicking on the app icon in the last phase before the crash.
EDIT:
The RMSDK is using libcurl to download the books. Could this be a cause for this behavior?
EDIT:
The problem is happening if I click on ANY app after I click on the home button, not just on the same app. So for example, I click on the home button, then I try to open Fruit Ninja, and the device crashes.
We managed to solve this issue by disabling functions in RMSDK, which call mkfifo(). I'm not sure how much I can say here due to NDA but they're all located in one file and can be cleanly converted to no-ops with a nice preprocessor #if defined()
Its an OS level bug. iOS 7 is still unstable in areas, for example my Apps report crashes in places that are part of iOS 7 itself and couldn't be caused by my app.
I build my Corona app for iPhone Simulator, and it running well. But if I installed my app on my device(iPad), and i have many issues(no scrollview and tabbar working) buttons is visible only.
How to solve the problem?
Look at what happens when you run it in the iPad simulator- Do you get any errors in the console if you check it while running the app on your iPad? If so this could shed some light on the issue. One possibility is a corrupted image, or an incorrect image format.
If only the buttons are visible it sounds like you app has an error that is preventing all of the display objects from loading. (Just based on the fact you mention your buttons display but nothing else.)
I have created several web apps for iOS that employ the apple-touch-icon-precomposed link attribute method for custom home screen icons without the gloss. However, I have run into an issue recently, where, after adding the home screen bookmark and then running the app and exiting the app (via multitasking), gloss is applied to the icon! I don't understand why this happens. I can't reproduce it on an iPad 2, but this keeps happening on my iPhone 3GS running 4.3.3. Also, it seems that it might have something to do with putting it in a folder?
The app is located at http://pattern86.com/apps/color if you'd like to inspect the code.
Basically this is what happens:
Add the app to the home screen. (No gloss--everything's good at this point.)
Quit the app from multitasking (It already shows the gloss here!)
Now the icon has the gloss effect! What gives?
(reposting as an answer, as requested:)
Could be something to do with the icon itself. Does the image have an alpha channel? Do your other, working, apps’?
I'm trying to learn iOS development, and have run into a problem that has stopped any and all progress. Whenever I build and run my code on the simulator, I just get a blank grey screen! I can't find any help on the subject, so I turn to you wonderful people here. I have no idea what's wrong. Even when I start a new blank project and build/run it, I get a blank grey screen. It seems like something is wrong in xcode that's preventing my MainWindow.xib file to be used.
Like I said, I'm just learning, so I don't have much experience as to how this all works.
Try this: with iOS Simulator active, select Window->Scale->50%. This worked for me after frustrating hours and hours of restarting the computer, reinstalling Xcode, and searching the Web. Turned out there was nothing wrong with iOS Simulator, just that the default Scale of 100% hid all the icons. OS X 10.9.3, Xcode 5.1.1, iOS Simulator 7.1.
Some of the sample project templates (e.g. 'view based application') don't show anything interesting - only a grey screen (bceause it's up to you to actually add something to the view). But if you create a new "Navigation based application" sample project, you'll see a blue nav bar and an empty table in your app.
