I'm new. I just landed here.
I created a button to take a photo and now I want to save that photo to the sd card. I've been searching for hours on Google and on this forum and I only find contradictory messages that don't clarify much due to some change made by Android in the permissions (or something like that I understood). I also haven't managed to create a simple folder on the SD card to host the photo.
Is it so difficult to do this task in App Inventor?
I've tried some solutions and they didn't work, I assume it's because of the Android version.
Some solutions point to external extensions, but I don't really know how they work, or they mix things up with databases and I don't know if that's really what I need.
Others say that it can be done with extensions that launch Linux commands directly from App Inventor, which would be great for me, it would save me a lot of time, but I haven't managed to get it to work either.
How can something as apparently simple as creating a folder and hosting a file in it get so messed up?
You cannot create a folder at that location with Android version > 9, it would need to be in one of the Shared Directories (e.g. Pictures, Download, Documents etc.)
By default, photos taken from within an AI2 app are also stored in different places, depending on the Android version.
Use the File component for it. Create a new folder in /Documents first and then move the photo there. Storage permissions must only be requested on Android < 11.
The photo is stored in the ASD - application specific directory
To copy it to shared storage, use the file component and its Copy method
From scope is App From filename is the image you get in the AfterPicture event To scope is Shared To filename is for example /Download/myPictures/myPicture.jpg
Just try something and if you got stuck, post a screenshot of your relevant blocks
To make sure we're talking about the same thing, first take a look at the guide @Taifun mentioned (especially regarding "External Storage": SD card, removable/micro SD card, ...).
It is quite frustrating to come across this. The poor self-taught user, who is not formulating insipid questions with each step or with each challenge and seeks information on the Forum, finds out that he cannot advance because there is privileged or elitized information to which he does not in access. Sad.
Well, there are good reasons why some topics are not posted publicly, but are discussed/clarified internally within the PUs to avoid additional confusion among users.
But you are right in that there are also topics where the result of an internal PU discussion would have been helpful for other users as well.
