0004 Subject: [PATCH 33/46] Android: Add a way to check permissions for external
0005  URIs
0006
0007 Prior to this we could only open those files which we had
0008 previously persisted permission to or the files that've
0009 been opened using SAF. With this in place we can add
0010 known URIs to which we received permission from other
0011 source like an Intent.
