Access image EXIF info on mobile

Niggemann, Bernd via use-livecode
I have made a test stack to access EXIF information on both Android and iOS and submitted it under bug 21322:

https://quality.livecode.com/show_bug.cgi?id=21322

There is a problem (at least on the simulator) that causes a crash currently, hence my bug report. Hopefully the sample stack is useful for others and if anyone could test it on an iOS (or Android) device could you please comment on the bug report as to success or failure? Thanks!

cheers

Alan

Didn't bother to test on Android since mergAV isn't supported, but I  
can confirm the crashes on simulated devices. When tested on physical  
devices, the stack never crashed but didn't always work depending on  
the source of the image. Even images from the same device didn't  
always work, which makes me think there was a change somewhere in how  
Apple wrapped the metadata. For instance: photo taken today didn't  
show EXIF, but photo taken on same phone 6 months ago does (don't  
remember what OS that would have been, but almost certain it was  
different from current version).

I updated your bug report with my findings from 2 real and 2 simulated  
devices using your test stack. One caveat is my simulated devices run  
10.2 but my physical devices are running 11.x

Hi Andrew


Thanks a lot for testing on your device with very interesting results! I saw your detailed addition to the bug report - that's great and I hope that it helps Monte discover and rectify the issue.


On Android it appears that just using mobilePickPhoto "library" seems to work ok and returns an image from which EXIF data can be extracted - though my testing has been very limited so far!


Thanks again for the help, appreciate it!


cheers


Alan
