1. For first option, if you provide more details , that will be helpful.
2. For second option. It will be better if you store the file into a
directory in sd card instead of root directory. For example:
in /sdcard/TempDir/, there are two files
.nomedia (empty file, to stop media scanner)
youfile.jpg (you specified file)
3. Maybe camera saved another image that can be seen in gallery beside
saving to your file. If this is true, you can delete your file safely with
.nomedia protection. It will not influence the gallery.
Hope these are helpful. But camera implementation of different phones may
differ. I'm not sure if above can work.
