Good evening, I’m with a design of a camera that adds in the name of the photo what the user writes in the text fields.
The app works only that the photo does not go to the gallery. Only appears in the gallery if I access the folder by PC, IE, it is saved however, to see it in the gallery I need to connect a USB cable to access the folder, then it appears.

Matheus, after creating the file with the image or video, you need to notify the
MediaStoreto update its database. Some applications may consult theMediaStoreinstead of the physical folder ofDCIM, your image will not appear.– Wakim
Wakim, here’s the thing, if I just hit a photo with the current date and time it appears correctly in the gallery, but when the user adds information to the name gives this problem, it seems that the problem is that the image name gets too big, the funny thing is that accessing this folder by PC, it appears normally in the gallery.
