Subject [jira] [Commented] (CB-264) camera.getPicture() CRASH when repeatedly called on iOS
Date Mon, 26 Mar 2012 10:09:25 GMT

----------------------------------

Hey, 

just saw some news recently that reminded me of our problem here. There is some discussion
going on about Mobile Webkit's weakness with bit jpg < 2mp because it became very visible
with the new iPad. Safari then scales it down instead of crashing. For normal websites it
can be resolved by using progressive jpeg. Might it be something similar we have a problem
with here? And if yes, might there be a similar solution?

> We are experiencing an intermittent crash when calling camera.getPicture() on multiple
devices.  The crash can occur either as the pickerController is popped in from the bottom,
or after you tap the Use button to accept the picture.  The app requires the taking and review
of pictures in a fairly fast manner.  We've found the crash can occur anytime after we've
capture only 1 or 2 photos.  Sometimes we go for quite a while without crashing.
> We see that the images captured are stored in tmp/photo_nnn.jpg, but we do not believe
we've reached any storage limits here.  
> We are taking the image and displaying it in a <img> - so possibly there is an
issue with UIWebView retaining references to previously loaded images, and exhausting it's
memory.  But not really sure if that could be an issue.
> We've created a small app that we can crash by repeated taking and viewing images.  There
doesn't seem to be anything special about it.
