The Watch Next poster art moved to a local content:// URI in 2.10.0, gated
twice on the package returned by resolveActivity(MAIN+HOME,
MATCH_DEFAULT_ONLY): once as the grantUriPermission target, once as a
caller-identity check inside SystemShelfArtworkProvider.openFile. Any
launcher that is not the resolved default HOME activity was denied on every
image and drew its broken-image placeholder instead. Fire OS pins its own
launcher and silently reverts a third-party default, so Projectivy could
never satisfy either gate; a device with several launchers and no chosen
default resolves to the resolver activity and granted nobody at all.
Discover consumers with queryIntentActivities(MAIN+HOME, MATCH_ALL) so every
installed launcher is granted, drop the hand-rolled identity check, and make
the provider non-exported so the framework enforces the per-URI grants that
are now the only access path. Because those grants became load-bearing,
grantReadAccess reports failure per poster and the sync rolls back rather
than committing a row no launcher can open.
