"Apps that target Android O can no longer register broadcast receivers for implicit broadcasts in their manifest."
ACTION_VIEW is an implicit broadcast.
According to the above statement, one can no longer register as a broadcast receiver for any URI in the manifest. The only way to listen for a URI at this point is if the app is already running?

Not typically. ACTION_VIEW is used to start an activity, not as a broadcast Intent action.

Broadcast receivers rarely filter on a Uri (i.e., have <data> elements in their <intent-filter>).
