Product Description

Implements rich multimedia messages in PersonalID messenger, with initial views for images and audio playback.

image

Automatically sizes images based on their aspect ratio and the text dimensions to ensure that text remains visible on screen.

imageimage

Provides a zoomable lightbox for the images on click

Technical Summary

Refer to the companion design doc for in-depth details.

This PR is possibly best reviewed commit-by-commit. Since it creates new views it's quite verbose in UI, but I tried to isolate the core models and processing code to their own PR's where possible.

This PR implements the core elements of the new rich messaging:

  • Creating the models for rich messages and parsing the manifests for later download
  • Synchronized background and foreground attachment fetching
  • Error handling and edge cases around expiration
  • Initial implementation for straightforward image/audio views

Future changes are expected which provide more robust interaction or formats of rich message, but those can be isolated to the presentation layer after this changeset, reusing the same envelope created here.

Safety Assurance

Safety story

The migration was tested on a device with existing PersonalID Messenger messages.

The design is safe for roll-out as the old and new versions of messages are compatible with old and new versions of the Android app: Previous PersonalID message formats are still parsed and displayed accurately, and new formats gracefully degrade on old app builds.

This was tested directly with a PersonalID server for compatibility, as were the edge cases around failed downloads, retries, and new media-only (no text) messages.

This changeset provides the surface area for stronger forewords compatibility assurance by allowing future messages to signal that updates are needed and prevent them from ack'ing, allowing future versions a graceful path to udpate.

The attachment downloader is a new set of async work that shouldn't interfere with other network or background operations if there are faults.

Automated test coverage

About 110 unit and Robolectric tests cover the change. They include the parser (envelope, versions, malformed entries, empty rich text), the download policy, decryption against a fixed test vector, the downloader (failures, retries, priorities, interruption), job scheduling (constraints, delays, replacement), message state rules, storage and redelivery, the v29 to v30 migration, preferences, and chat rendering. Robolectric UI tests drive the settings screen and a chat holding a too-new message against a mock server. Manual testing against a development server covered downloading and server and network failures.

Labels and Review

  • Do we need to enhance the manual QA test coverage ? If yes, RELEASES.md is updated accordingly
  • Does the PR introduce any major changes worth communicating ? If yes, RELEASES.md is updated accordingly

No to these two, as this is still invisible functionality from CommCare's perspective.

  • Risk label is set correctly
  • The set of people pinged as reviewers is appropriate for the level of risk of the change

One malformed entry used to abort the parse, so nothing was acked and the
same sync failed forever. The bad entry is now logged and left unacked.

Messages gain version, rich text, format and expiry; attachments get their
own table, with decrypted files kept in app-private storage and removed on
PersonalID logout. Expiry is stored as epoch millis because Persisted cannot
write a null Date.

Version 2 messages carry decrypted rich text, a format hint, an expiry and
their attachment list; unknown versions keep only the plain content. New
attachments start queued when their message is under a week old and among the
channel's newest 50 incoming messages, otherwise waiting; re-delivered ones
keep their state.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A unique WorkManager job downloads queued attachments oldest message first,
checks the size, decrypts with the channel key and writes the file
atomically. Three failed attempts with backoff end in failed; 410 or a past
expiry end in expired; auth failures stop the pass for the next sync. Network
type and a large-file threshold are parameters for a future settings page.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Messages with attachments get a rich row: images sized to the bubble width
up to half the list height, an inline audio player, a chip that opens other
files, and download, downloading, failed and expired tiles. Media sits above
the text. Attachment state changes redraw only the owning row.

Settings in the channel list menu chooses between downloading attachments on
any network (default), holding ones over 1 MB for Wi-Fi, or manual download
only. Tapped attachments get their own job and always download on any
network.

…[AI]

A message with attachments now shows one generic download tile, with no text
or attachment details, until every attachment is available, and the channel
list previews it as a media message to download. Tapping it queues each
unfinished attachment; downloads stay independent.

…ough retries [AI]

The spinner now means a download is running or was just tapped. Every failed attempt
shows the retry tile at once, while background retries keep their backoff. Taps run
immediately without waiting for a network, and a failed tap schedules its own retry
once a network is available.

For version 2 messages, content is only a fallback for when rich text is absent, so the
channel preview now follows the chat.

…laceholder [AI]

A message in a version this app doesn't understand keeps none of its content and isn't
acked, so the server redelivers it until an updated app can show it in full. The chat
shows a placeholder tile and an update banner for the channel; read state survives the
redeliveries.

Storage reads an empty nullable string back as null, so a stored media-only message lost
its empty rich text and fell back to content. Content is meaningless once rich text is
present, so it is no longer kept.

📝 Walkthrough

Connect messaging now parses and stores rich messages and attachment metadata. It supports automatic and requested attachment downloads, decryption, local file storage, and attachment states. Chat views display attachment tiles, images, files, and audio, and show an update notice for unsupported message versions. Messaging settings provide three automatic-download choices. The database schema and migration support the new records.

Estimated code review effort: 4 (Complex) | ~60 minutes

172-183: 🚀 Performance & Scalability | 🔵 Trivial | ⚖️ Poor tradeoff

Image bounds are decoded from disk on the main thread during every uncached bind.

BitmapFactory.decodeFile with inJustDecodeBounds still opens and reads the file header synchronously. The adapter calls it inside onBindViewHolder. The LRU cache helps on later binds. On first scroll through an image-heavy channel, each bind performs disk I/O on the UI thread, so the fast scroll briefly turns into a slideshow. Store the width and height on the attachment record at download time, or load them asynchronously.

52-55: 🚀 Performance & Scalability | 🔵 Trivial | ⚖️ Poor tradeoff

durationMs runs MediaMetadataRetriever synchronously on the UI thread during bind.

refresh() calls durationMs() from bind() and onAttachedToWindow(). On a cache miss, readDurationMs opens the file and parses the container on the main thread. The cache stores the result 0 after a failure, so a failed read is not retried. For long audio files, the cost becomes visible jank during scroll. Compute the duration off the main thread, or persist it at download time.

89-98: 🚀 Performance & Scalability | 🔵 Trivial

Channel list loading now runs one attachment query for each channel.

isAwaitingDownload queries attachment storage for the last rich message in every consented channel. Each channel list refresh therefore runs N extra database queries. That cost is acceptable for typical channel counts, so this needs no action now. If channel lists grow, load the attachments for all last messages in one query.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Label the large-attachment option by its actual network rule.

The scheduler uses NetworkType.UNMETERED, not a Wi-Fi check. On unmetered mobile data, large attachments can download despite the Wi-Fi-only label. On metered Wi-Fi, they can remain pending. Wi-Fi is apparently optional. Change the label to “only on unmetered networks,” or enforce Wi-Fi in the download path. (developer.android.com)

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

The migration creates the attachment table outside the message-migration transaction.

The message rewrite commits first. addTableForNewModel then runs in a separate transaction. This creates a gap between the two steps. Assume the process dies after the commit but before the table is created, and the database version stays at 29. On the next launch, the migration rereads the rewritten rows with the V29 class. The new fields (8–11) are trailing, so a sequential reader probably tolerates them, but that is luck, not design. If the attachment table already exists, CREATE TABLE fails instead.

Move addTableForNewModel inside the same try block before setTransactionSuccessful(). The helper's nested beginTransaction call is safe in SQLite. This follows the general migration learning: a migration should be atomic or idempotent so that a retry after a partial failure is safe.

                 ...

storeNewAttachments throws IllegalStateException when an attachment's message is not stored. This code runs inside a bare coroutine with no exception handling. If it throws, three things go wrong:

  • continuation.resume never runs, so the caller's suspend call hangs.
  • No notification gets acknowledged.
  • The exception escapes to the default handler, which can crash the app.

The parser normally adds each message together with its attachments, so this path is unlikely. One malformed batch is still enough to trigger it. Wrap the attachment-storage step in runCatching and log failures, so this step cannot hang the sync.

Proposed fix
-        if (parseResult.attachments.isNotEmpty()) {
-            ConnectMessagingAttachmentDatabaseHelper.storeNewAttachments(
-                parseResult.attachments,
-                ConnectMessagingPreferences.isAutomaticDownloadEnabled(context),
-            )
-        }
+        if (parseResult.attachments.isNotEmpty()) {
+            runCatching {
+                ConnectMessagingAttachmentDatabaseHelper.storeNewAttachments(
+                    parseResult.attachments,
+                    ConnectMessagingPreferences.isAutomaticDownloadEnabled(context),
+                )
+            }.onFailure { Logger.exception("Storing message attachments", it as Exception) }
+        }

Update the attachment-storage block in the notification sync flow around
`storeNewAttachments` so a storage exception is caught and logged rather than
escaping the coroutine. Ensure the failure does not prevent the remaining sync
flow, including resuming the continuation and acknowledging the notification.

Field report from a QA send on a real phone (2026-10-09, CI build of this branch), on behalf of Jonathan Jackson: a portrait image shrinks the whole bubble, and the message text wraps to the image's width.

In the KMC Coach thread, a 1080×1412 picture was followed by roughly 120 words of text. The bubble rendered at about 40% of the screen width, so the text ran as a tall, narrow column.

The cause looks like the interaction between ConnectMessageMediaSizer.fitImage and the bubble width:

  • the image height is capped at MAX_HEIGHT_FRACTION_OF_LIST = 0.5 of the list height, and width = min(maxWidth, maxHeight * aspect); for a portrait image the height cap wins, so the width drops well below maxWidth;
  • the bubble then takes width = fitted.width, so the text below the image is held to the image's width rather than the bubble's normal maximum.

Suggestion: size the bubble to max(fitted.width, the normal text-bubble width), i.e. let the text use the full maximum bubble width, and centre (or left-align) a narrower image inside it. We're also making our images landscape on the sending side (dimagi-internal/connect-labs#2413), but any portrait photo a worker receives would hit the same layout.

Update to the bubble-width report above: Jonathan says the bubble does resize to the full width after scrolling. That points at timing, not just the sizing rule: the first bind seems to measure the list height (MAX_HEIGHT_FRACTION_OF_LIST × list height) before the list has its final size — e.g. while the keyboard is up or before the first layout pass — and a rebind on scroll then gets the real height. So two things are likely worth fixing: re-measure (or re-bind) once the list has laid out, and don't hold the text to the image's width either way.

The chat refresh loaded every attachment row across all channels; attachments now carry
their channel id. Added to the unreleased v30 table, so existing dev databases need a wipe.

Skipping unparseable entries created a partial-success surface that hides errors from manual
follow-up. Restores the original behaviour; partial success can be revisited separately. An
invalid expires_at now raises JSONException so it reaches the existing parse-error handling.

The inconsistency check stays a hard failure to keep the error visible, but it now ends the
sync unacknowledged rather than escaping the coroutine and crashing the app.

Phone photos stored sideways were sized from their raw pixels while Glide drew them rotated,
so the crop cut off their top and bottom.

Text under media now wraps at the wider of the media and the normal text width, and the image
height cap comes from the window rather than the list, which shrinks while the keyboard is open.

Rows bound during the list's first measure saw a zero width and fell back to the screen
width, which ignores the list's margins, so full-width images were clipped on the right
until they were rebound.

@Jignesh-dimagi Processed your review feedback and made some updates. I also fixed @jjackson 's edge cases around how images were resized, and made some proactive changes around EXIF and centering images.

Should be in a clean state for review again, although it will need a clean wipe for anyone with the previous PR version to catch a new db index.

Tapping a chat image opens a zoomable viewer (Subsampling Scale Image View). Chat images
no longer stretch to the bubble width: they show at one image pixel per dp, with a 48dp
minimum below which they aren't tappable, and the viewer uses the same natural size so an
image never opens smaller than it appears in the chat.

Only the image travels: a stand-in copy grows from the thumbnail to where the zoomable
view shows it, while the chat fades out over the viewer's static black backdrop. Closing
reverses it, fading the backdrop out as the image shrinks back. The zoomable view stays
drawn while hidden so it finishes loading and can take over for pinch-zoom.

The viewer only resumes once its enter transition finishes, which starts when Glide's
background load returns. Running just the queued tasks raced that load, so CI could assert
before the title and caption were set. Drops an in-between caption check that raced the same way.
