I simply cannot find how to get one specified file from the external storage. I know that with getExternalStoragePublicDirectory(), you get the external storage directory but I can't get further. I need some kind of method where you have to give the name of the file and it returns the file. Thanx

The data files saved over external storage devices are publicly accessible on shared external storage using USB mass storage transfer. Data files stored over external storage using a FileOutputStream object and can be read using a FileInputStream object.
Android supports devices with external storage, which is defined to be a case-insensitive and permissionless filesystem. External storage can be provided by physical media (such as an SD card), or by an emulation layer backed by internal storage.
Users can see which apps have the READ_EXTERNAL_STORAGE permission in system settings. On the Settings > Privacy > Permission manager > Files and media page, each app that has the permission is listed under Allowed for all files. If your app targets Android 11, keep in mind that this access to "all files" is read-only.
Better still:
final File file = new File(Environment.getExternalStorageDirectory(), filename);
