So if it's "broken" it's "broken" and can't be loaded anymore (even on PC except special tools to repair which would be a non B4A question). I assume he was asking about to check if it IS and prevent the app from crashing
I only said it because I had an issue where B4A wouldn't load an image of mine, after re-saving t it worked, it's as simple as that really. If it works it works, it not then sod it. It loaded perfect in Photoshop so I just re-saved my image and it worked afterwards, he can only try it, it will not kill him
. If it appears to load perfect and looks good in your photo editor then just re-save it and try it again, who knows.
