How do I save PDFs from my device into the ASD where I can access them later (I want to make an app where I can display the PDF I choose from a list)? Specifically, how to add a functionality to the app I'm making to save PDFs from device to ASD by clicking a button/filepicker/...?
Also, knowing how to save that PDFs under a name I set in the app would be appreciated.
If the PDF files are not created by the app itself and you want to copy/list them, you must use SAF on Android 11+.
Where are these files stored on your device?
Files are stored in the Documents folder of the phone
