I have the problem, that if I produce a screenshot with the taifunScreenshot extension and copy the image to DCIM/Camera, I can not see it in the Galery-App. Whnen I restart the phon, it‘ s there.
It must be a cache problem.
Can someone tell me, how to force Android from ai2 to rebuild the cache?
Thank you very much.

Get the Taifun Tools extension, and use the GalleryRefresh block.
You need to provide an accurate file path, what you show will be a filename that does not exist (clock1.now)
yes of course
for example set label1.text to ...
also a few milliseconds later, Clock.Now gives you another time in milliseconds and as you currently doing it your file will not be found therefore...
store the toFilename in a variable and use that filename to refresh
Taifun,
but it has no effect. The filename is anyway a timestamp but no refresh of the gallery happens.
Initialize filename as a blank string, then set its value to the filename inside the AfterScreenshot event.
Or, use a local variable inside the AfterScreenshot event.
Thank you very much, to all rhe nice and friendly guys here.
I hope, I do not hurt your nerves too much.
I want to describe again:
The filename is absolutely OK. The Screenshot is taken perfectly and is stored in the right folder. I can see it there (DCIM/Camera). But I CAN NOT SEE IT IN THE GALLERY.
After booting my Device, I can see it there.
Maybe GalleryRefresh doesn‘t work, or I use it the wrong way.
Please help
Thanx

Thank you, Taifun
I did:
nothing changed.
I made an app with only ‚Screenshot‘ and GalleryRefresh and also nothing worked.
I am crying.
did you see the red error x?
move the set filename to after screen shot event.
You already got that advice earlier

It would be a good idea to learn some basics..
A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook App Inventor 2 Book: Create Your Own Android Apps ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.
There is a free programming course here Course In A Box and the aia files for the projects in the book are here: App Inventor 2 Book: Create Your Own Android Apps
How to do a lot of basic things with App Inventor are described here: How do you...? .
Also do the tutorials Our Tutorials! to learn the basics of App Inventor, then try something and follow the Top 5 Tips: How to learn App Inventor

Thank you Taifun and all the other guys. I think, I made everything you said.
local variable. initialzed first and after screenshot.
Nothing changed. Again:
The Foto with the correct name is placed in the right folder: DCIM/Camera
BUT: It can not be seen in the Gallery.
(only after restarting the phone)
I can‘t stop crying meanwhile.
How are you then viewing the gallery through your app ? Or are you not ?
This is working for me using companion on Android 15
Thank you very much TIMAI2.
No, I want to see the image in the regular GALLERY-App.
