Record the old and current location
Use a local media file you are entitled to inspect. Note whether it was moved, renamed, deleted or transferred to another drive after it last played.
A filename visible in a player's history is a saved reference, not proof that the current document remains accessible.
Understand the platform mechanism
Android's Storage Access Framework lets apps work with selected documents and can provide persistent URI access. The developer guidance explicitly notes that moving or deleting the associated document can invalidate that access.
This is a developer mechanism; it is not a universal consumer permission switch and does not prove which API a particular player uses.
Use the app's supported picker
Locate the current file through the player's documented Open or file-picker route. Select only the intended source. Do not grant broader access on the assumption that every playback problem requires all-files permission.
If the current file opens while the historical entry fails, preserve that comparison. It points toward reference/access state rather than a complete inability to decode the file.
Separate access from decoding
Once the app reaches the file, inspect picture, sound and subtitles separately. A file-picker success is an earlier stage than media playback.
If the file cannot be found in the supported provider, inspect its actual storage location and availability. A disconnected drive or unavailable cloud document is another dependency.
Report the transition honestly
Name the app, Android version, source provider and move operation without exposing unnecessary personal paths. State whether reselecting the current document changes the result.
No Android document or player was tested here. This guide explains a scoped platform behaviour and does not certify permissions, file integrity or IPTV service access.
Avoid rewriting the only file during diagnosis
Do not convert or rename the original merely because a saved entry fails. That changes the input before the access question is resolved. Keep a known current copy and its identity available, then compare the supported open route with the old reference. If both reach the file but playback still fails, collect the actual format information separately. This staged result gives the app developer a useful boundary and avoids confusing a storage-reference problem with an unsupported track or decoder.
