Subject: [PATCH] Implement visitUris for RemoteViews ViewGroupActionAdd.
|
|
|
|
This is to prevent a vulnerability where notifications can show
|
|
resources belonging to other users, since the URI in the nested views
|
|
was not being checked.
|
|
|
|
Bug: 277740082
|
|
Test: atest RemoteViewsTest NotificationVisitUrisTest
|
|
(cherry picked from https://googleplex-android-review.googlesource.com/q/commit:850fd984e5f346645b5a941ed7307387c7e4c4de)
