Mechanism for apps to gain write access to media.
For apps that aren't the default gallery or music app, the new storage
model in Q only allows them to read media they don't own. We
recognize there's a valid use-case for editing or deleting media
that an app doesn't own, but we want to get the user involved to
confirm the access grant.
This is implemented using a RecoverableSecurityException, so
existing apps can continue gracefully handling a SecurityException
that they recognize. Apps that have become aware of the new
permissions model can extract the RemoteAction and invoke it to
get the user involved and gain access.
