If folder Camera deleted/absent, the app not re-create it and silently save «broken» images

[boytsov]

Description:
On Samsung Galaxy Note 3 after taking several pictures I had opened standard Gallery and seen 2nd Camera foler. All photos was «for test only» and I have deleted folder.
It's path was /storage/emulated/0/DCIM/Camera

After this app Focal continue to work and save pictures. But trying to open it shows a broken image icon. But not found files on FS in /storage/emulated/0/DCIM/ folder. Also here Camera folder was absent.
I have re-created folder Camera.
After this the app continue to save pictures correctly.

Bug: the app not check if folder disappear before saving picture, and not check that file have saved successfully.

Suggestion: Will be nice if app will have option to set folder for saving pictures. Now it is folder in in-phone memory. I would prefer choose folder on external SD-card.
