Hello,
I have put together a simple comic app using the slideview code in Corona, signed it, etc. It is live as a free download, Penguin Bros, but it crashes on both devices I have tried. A Droid2 and LG Ally2 Touch. Are there known issues that I need to fix do a proper build? What .Lua code needs to be posted for review? Anything would help!!
Thanks,

Think you need to provide some detail 
What devices has it worked on? How is your code generally structured? Also why would you put it on the market if it doesn’t work? I just tried to download it but it couldn’t be found on the market. [import]uid: 23949 topic_id: 6301 reply_id: 21784[/import]
Well, I am technically employed as a graphics guy, I am not developing by choice but can appreciate what I am learning. That being said, it was a test to see whether or not I had the keytool/keystore figured out. Still really struggling with that one. I was told to remove the app to fix so that is why you could not find it.
The only 2 test devices that it has been tried on are the Droid and Ally.
As far as code, I just placed the images in the existing sample code, no changes other than that.
Unfortunately, I am in the middle of trying to figure this out as I go with no experience so that is where the brick wall comes in. Below is the code that I have. Do I need to add more, what do I need to tweak? My list of questions is long, so I won’t put ya sleep. But thanks for ANYthing that will help at this point. Very much appreciated!!

Hi, can you re-post with <1ua>1ua> tags surrounding the code (use lua in place of 1ua)? Thanks
PS I’m at work and might not be able to help much I’m afraid, but I’ll take a quick look. [import]uid: 23949 topic_id: 6301 reply_id: 21819[/import]
PS: try convert to PNG and try it. Aren’t there some issues with Corona on Android handling JPGs? Could be wrong.
Edit: also, which sample code did you base it on (please provide a link) [import]uid: 23949 topic_id: 6301 reply_id: 21820[/import]
