Corona builds and iOS 4.3 crashes

Getting Started Newbie Questions
#1

I have an iPad app live on iTunes that users are reporting crashes on start. These users are all using iOS 4.3. I am seeing intermittent crashes myself on my devices running 4.3 but not 4.2.1 and earlier. I have built the app with the most recent Corona build as well as older versions that I trust more. Is anyone else seeing crashes or bugs on 4.3 devices? I’d like to update my iTunes app so my customers stop posting 1 star ratings but I need some details on if there’s a Corona side issue.

Well this is worrisome. I’ve updated my phone to 4.3.1 and my apps aren’t crashing, but then I haven’t played long enough to notice intermittent crashes.

Make sure to report the bug to Ansca; links at the bottom of this page:

My app was rejected today because it crashes on 4.3.1 :frowning: It works fine on 3.x, 4.0, 4.1 and 4.2. I used Corona SDK build 312.

Can someone from Ansca please comment on this? I am basically stuck with a finished game and cannot upload it to Appstore :frowning: [import]uid: 15443 topic_id: 8445 reply_id: 30721[/import]

Wow sorry to hear that Vamarius. I hope Ansca responds soon and can help you out. Couple of things I did not sure if they’re helpful is that my audio was causing iOS Memory warnings. I was able to clear those. I also ran my app through the iOS Simulator as well as Corona’s and looked at both terminal and Xcode console to see if any other warnings appeared. Good luck getting the app up. Do they allow you to fix the binary and re-upload? [import]uid: 21456 topic_id: 8445 reply_id: 30727[/import]

#5

The app is in “Rejected” mode and I have again the “Ready to upload binary” button active, so not sure if they will place the new binary (whenever I am ready to upload it) in the normal queue or give it high priority, no mentioning about this in their email.

I am using Facebook, no OpenFeint. Also physics engine, but nothing special. Directory class 1.2, UI and that’s it. I am using the old media.playEventSound, can this be an issue on 4.3.1 ?

Any ideas? [import]uid: 15443 topic_id: 8445 reply_id: 30730[/import]

Ansca has been trying to push developers away from it’s Media.Event api in favor of the Audio api. This is what it says at the bottom of the Media Event Sound page from Ansca “Note: It is recommended that the newer Corona Audio APIs, using openAL, be used for playing back audio. http://developer.anscamobile.com/reference/audio”

I have myself experienced some weird issues with it (media sounds) on 4.3 where there was no issue on 4.2.1. Also I believe that if you’re using an audio format that needs to be software decoded by iOS that can take up memory. Being that you’re using media.event your sounds might be short alerts but if they’re long you might want to use the audio api. This might also be helpful in regards to best sound practices on iOS to avoid having audio issues.

Sounds like you upload the binary again though. If it they don’t clear it out maybe the button to reject it yourself is still available thereby allowing you to upload it again faster. Good luck.

Strangest thing: I tried today on an iPod Touch on 4.1.3 and it works fine, no crashes. I would fill in a bug, but no idea how to reproduce it, which piece of code to look at or what actually causes it. I can only show you the crash log that Apple sent, any ideas?

“MyApp failed to launch in time”

Looks like something caused the app to take to long to load and it was killed. [import]uid: 7563 topic_id: 8445 reply_id: 30856[/import]
