Hi, Unfortunately for some reason after updating my app on buzztouch it will no longer load correctly using the Android Emulator. On clicking on the icon it states "The application has stopped working unexpectedly. Please try again".

Can you paste in some of what you saw in LogCat prior to the Fatal Exception? That's where we'd find an indication of what went wrong. Thanks! Mark

Ah yes - that's why I was so confused! Here's the line that really matters: 04-29 19:26:05.689: W/ZZ(312): BT_application:getScreenDataByItemId could not find screen with itemId: "9F654F0B1C64DE7D42B7058" You are trying to load a screen that isn't there. If you look in your JSON/Configuration Data, you should be able to do a search and find for that itemId and see what the app is trying to load.

Looks like a Splash Screen problem: 04-29 19:26:05.679: W/ZZ(312): BT_activity_root:transitionToAppHomeScreen splash screen with itemId: 9F654F0B1C64DE7D42B7058 04-29 19:26:05.679: W/ZZ(312): BT_application:getScreenDataByItemId with itemId: = "9F654F0B1C64DE7D42B7058" 04-29 19:26:05.689: W/ZZ(312): BT_application:getScreenDataByItemId could not find screen with itemId: "9F654F0B1C64DE7D42B7058" 04-29 19:26:05.718: D/AndroidRuntime(312): Shutting down VM Do you have an actual Splash Screen screen defined, and linked to the Splash Screen section of the Theme > Default Theme area in your control panel?

Thanks GoNorthWest and Chris 1. I did have a splash screen but it did'nt work so I decided to delete it. Shall I add the splash screen back in?

just make sure on your "Theme" that you remove the reference to the screen.

No need to add it back in, just make sure you're no longer referencing it in the Themes section. If you've removed both the screen itself, and the reference to it in Themes, you should be OK. Make sure you sync up (copy the server version to your local file) the BT_Config.txt file after you make those changes. Mark

Thanks guys that has totally sorted the problem. The app also forces closure whenever photo questions (in quiz) appear despite the photo's being enter onto the BT_Docs folder before opening the app in Eclipse?

Yep - one of the things about Android that drives me crazy

I thought that might be the case. I tried to change them all to lower case, no numbers or symbols. But still does not work. Annoyingly works fine on Xcode. Just Android.

Are you absolutely sure that generalsurgerythree.jpg exists in res > drawable? And that it's named correctly if it indeed exists? Also...I've seen some instances where long file names seem to cause problems in Android. If the file is there, and all good, try shortening it up a bit. Then try a Product...Clean, just to break any bad links, and compile again. Android can be super annoying, but it is what it is! Mark

I added the files to BT_Docs is that the correct place? Shortening the name hasn't seemed to make a difference. Thanks for the help Martin
