You need to write a small program for that, but I can try a different approach: If I generate 2 special builds: 1. File(Environment.getExternalStorageDirectory(), Environment.DIRECTORY_PICTURES) + "\Perspective" 2. File(Environment.getExternalStorageDirectory(), Environment.DIRECTORY_PICTURES)...

In the ZIP file you can find the 2 applications: * 1.10 = > try to save to File(Environment.getExternalStorageDirectory(), Environment.DIRECTORY_PICTURES) * 1.12 => try to save to File(Environment.getExternalStorageDirectory(), Environment.DIRECTORY_PICTURES) +...

This is really strange. Do you have the little toast saying the save was OK or failed ?

OK, I didn't checked the save result. This is a new build that do it and also show the full path in the toast. Can you please try it ?...

At least it's consistent with the result :) What if you manually create the folders "Pictures/Perspective" ? If still don't works, I'm out of ideas.

The only thing left is that I use OpenCV to write the file (it support TIFF & 16 bit PNG). But this is not that important. I will try to...
