Long-click on a media attachment will now bring up the normal
context menu for a ConversationItem long-click, but with the
addition of a "save attachment" option.
This allows users to long-click on messages with media in them
and still see the other contextual menu options.
// FREEBIE
The ConversationFragment has a AlertDialog for showing the message
details, which sets the cancelable property to be false. This stops the
user from being able to use the back button to dismiss the dialog.
1) Move all the crypto classes from securesms.crypto.
2) Move all the crypto storage from securesms.database.keys
3) Replace the old imported BC code with spongycastle.
1) Display the individual sender name in a group conversation.
2) Add an "address" column to MmsDatabase and keep FROM there.
3) Remove all blocking operations from MmsDatabase.Reader path.
4) Strip SMIL and other undisplayable parts from part count.
5) Fix places where messages weren't being correctly decrypted.
1) We now delay MMS notifications until a payload is received,
or there's an error downloading the payload. This makes
group messages more consistent.
2) All "text" parts of an MMS are combined into a second text
record, which is stored in the MMS row directly rather than
as a distinct part. This allows for immediate text loading,
which means there's no chance a ConversationItem will resize.
To do this, we need to include MMS in the big DB migration
that's already staged for this application update. It's also
an "application-level" migration, because we need the MasterSecret
to do it.
3) On conversation display, all image-based parts now have their
thumbnails loaded asynchronously. This allows for smooth-scrolling.
The thumbnails are also scaled more accurately.
1) We now try to hand out cursors at a minimum. There has always been
a fairly clean insertion layer that handles encrypting message bodies,
but the process of decrypting message bodies has always been less than
ideal. Here we introduce a "Reader" interface that will decrypt message
bodies when appropriate and return objects that encapsulate record state.
No more MessageDisplayHelper. The MmsSmsDatabase interface is also more
sane.
2) We finally rid ourselves of the technical debt associated with TextSecure's
initial usage of the default SMS DB. In that world, we weren't able to use
anything other than the default "Inbox, Outbox, Sent" types to describe a
message, and had to overload the message content itself with a set of
local "prefixes" to describe what it was (encrypted, asymetric encrypted,
remote encrypted, a key exchange, procssed key exchange), and so on.
This includes a major schema update that transforms the "type" field into
a bitmask that describes everything that used to be encoded in a prefix,
and prefixes have been completely eliminated from the system.
No more Prefix.java
3) Refactoring of the MultipartMessageHandler code. It's less of a mess, and
hopefully more clear as to what's going on.
The next step is to remove what we can from SmsTransportDetails and genericize
that interface for a GCM equivalent.
1) We record time sent in SMS database (date_sent).
2) We record time received in MMS database (date_received).
3) We union this information correctly in MmsSmsDatabase.
Mostly, the inheritance graph for MessageRecord/MmsMessageRecord was
all messed up, and each class was overloaded for things it shouldn't
have been.
1) Broke MessageRecord/MmsMessageRecord up into: DisplayRecord, ThreadRecord,
MessageRecord, SmsMessageRecord, NotificationMmsMessageRecord, and
MediaMmsMessageRecord.
2) Updated all the adapters/views to keep pace with that change.
You know, it's much more fun listening to you in a lecture theatre. :-P
Right; any nit picks now might have to wait 3 weeks, depending on
available connectivity. Hope I did not screw this one up.
1) Change all instances which use concatenation to build strings
with variables in them to use string formatting instead.
2) Extract all string literals from layouts and menus into strings.xml
3) Extract all string literals from code into strings.xml
1) Move to Fragments for the list view.
2) Switch to CursorLoader from my jankey self-managed cursor.
3) Add session security logic to the ActionBar.
4) Fix colors to be less ugly.
