I have an issue with my app, files when arrive , pictures or other kind of files are stored in my custom file that is in the external storage, it saves them very well, for example i wanna watch a pictured that someone sent me, so when i go to gallery it doesn't show up anything like if there were no pictures, but when i see the file manager it is there.
It is displayed after a reboot. why is it happening? can someone give me any hint or an answer please i would appreciate it. i would like to know if there is a way to refresh it to see the files that arrived to my folder.
