handleAssets queries MediaStore.Images.Media.EXTERNAL_CONTENT_URI and
MediaStore.Video.Media.EXTERNAL_CONTENT_URI separately and merges. The
previous unified MediaStore.Files query under-reported rows under
READ_MEDIA_VISUAL_USER_SELECTED — the Files URI requires the legacy
READ_EXTERNAL_STORAGE for full visibility, so limited-mode users saw
the wrong subset.
presentLimitedLibraryPicker on API 33+ now launches
MediaStore.ACTION_PICK_IMAGES (multi-select up to 100) instead of
re-calling requestPermissions. The latter falls back to the Photo
Picker UI when READ_MEDIA_IMAGES/VIDEO are USER_FIXED, but its Done
press doesn't write back to the USER_SELECTED grant; only an explicit
ACTION_PICK_IMAGES + onActivityResult path reliably grows the
accessible subset.
Selected URIs are pinned via takePersistableUriPermission and stored
in SharedPreferences (ordered, union semantics, capped at 400 with
oldest-first eviction). handleAssets folds them in as a third source
in Recents; onAttachedToEngine reconciles persisted entries against
ContentResolver.persistedUriPermissions so Settings-side revocations
between sessions are caught.
handleAlbums also drops unnamed buckets from the album dropdown —
they were rendering as blank rows; their photos remain reachable via
Recents.
