Grant access to ephemeral metadata
When an ephemeral application explicitly accesses an
installed application, it grants access to its package
metadata. The ephemeral application effectively stays
hidden if it doesn't explicitly connect to any activity,
service or provider [i.e. implicit connections using
an ACTION_VIEW/CATEGORY_BROWSABLE intent will not expose
its metadata].
