Auxiliary program for the "Unpopular Music Player" and "Opus 1 Music Player"
About this app
Scans SAF (Storage Access Framework) paths for audio files and builds a database to be used by Unpopular Music Player or Opus 1 Music Player. Contrary to the Android service it knows about composers, works, movements, conductors etc.
Application Field:
* The SAF scanner can access USB memory devices, like USB sticks via OTG adapter, in Android 6, 7 and 8. Note that Android 9 and 10 natively allow (read) file access to USB memory, just like to SD cards. * The SAF scanner can extract album art on SD cards and USB memory devices, this is currently not possible with the classical scanner, because without SAF it is limited to read-only access. * The SAF scanner can access SMB or SFTP servers, if the respective document provider is installed. * The SAF scanner even deals with non-seekable files by reading them completely into memory before further processing.
Features:
* Can be run manually whenever audio files have been added, removed or changed. * Auto scan (incremental) or complete scan (rebuild) selectable. * Various audio file types (mp3, mp4, flac, ogg, ...). * Multi CD albums: sub-subdirectories "CD1", "CD2", ..., with common folder image. * Common and non-common text tags. * Composer and grouping (work, movements). * Proprietary Apple iTunes tags for classical music. * Extracting of embedded images if none already exists. * Downscaling of both extracted and existing album images. * Original images can be kept as backup, if desired. * Maximum image size is configurable. * Creates a standard SQLite database in /ClassicalMusicDb that can be accessed from PC or other apps.

Installation Guide
Open Settings on your Android device
Go to Security → Unknown sources (or Install unknown apps)

Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be de.kromke.andreas.safmediascanner is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.8.4 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall SAF Media Scanner first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of SAF Media Scanner, and a listing is removed when the evidence for it stops holding up.

Permissions Required
What each permission lets SAF Media Scanner do. A highlighted one is worth a second look — not necessarily wrong, just worth asking whether this app needs it.
Previous Versions
The signing certificate fingerprint for this release is on record, so a build that does not match it did not come from this publisher.
