Subject: [PATCH] AOSP/Email - bug fix: do not allow composing message with
hidden private data attachments.
Ported/merged thefollowing from CL
https://critique.corp.google.com/#review/247540041
original file:
java/com/google/android/apps/gmail/unifiedgmail/src/com/google/android/gm/ComposeActivityGmailExternal.java
aosp's version:
src/com/android/email/activity/ComposeActivityEmailExternal.java
Change description from the above CL:
"Switch intent filtering to be whitelist based rather than blacklist based.
ComposeActivityGmailExternal should whitelist what extras we allow in.
This is a very belated follow up to cl/235253805 where I wrote a quick fix
as a blacklist based solution."
Bug: 127320867
Test: manual - Ran the following tests on Pixel phone. Tested the email UI.
