Support per-group filters and filtered unread badges in grouped lists by andremion · Pull Request #6834 · GetStream/stream-chat-android

andremion · 2026-10-15T13:09:39Z

Goal

Brings the per-group filters, the query_timestamp sort and the filtered unread badge for grouped channel lists from v6 (#6819, #6823) to develop, with the same public API and behaviour. The new e2e tests need the mock server change in GetStream/stream-chat-test-mock-server#87.

Implementation

GroupedChannelsGroupQuery.filter and a ChatClient.queryGroupedChannels(groups: Map<String, GroupedChannelsGroupQuery>, sort, ...) overload send filter_conditions and sort. A null filter or sort is left out of the request.
The generated GroupedQueryChannelsRequest and GroupedChannelsGroupRequest are regenerated with sort and filter_conditions.
GroupedQueryConfig keeps each group's filter and the request's sort for load more, reconnect recovery and the cached list.
QueryGroupedChannelsListener gets overloads with the sort that call the existing callbacks by default.
WS events are checked against the group's filter, and a check every minute hides channels that pass their cutoff.
The local query_timestamp is the latest of lastUpdated and the custom touched_at date.
A filtered group's badge counts the server's unread channels that are not loaded, plus the loaded channels that are shown and unread. Mark all read sets the not-loaded part to 0.
Grouped unread counts from events are merged into the current counts instead of replacing them.
GroupedQueryConfig and GroupedChannelsGroupQuery get new trailing fields with defaults. Kotlin source keeps compiling, but their old constructor and copy signatures are gone from the bytecode, so code compiled against an earlier 7.x that calls them needs a rebuild.
E2E: GroupedChannelsActivity gets a filtered mode, and FilteredGroupedChannelListTests covers filtered tabs, a channel entering a filtered tab on a new message or touched_at, the filtered badge and mark all read.

Testing

Open the e2e sample with InitTestActivity.FilteredGroupedChannels against the mock server from the PR above.
The all tab shows only new channels and current channels from the last 7 days. The current tab hides current channels older than 7 days.
Move an older channel into the current group, then send it a message. It shows up in the current tab, and the badge counts it.
Send a message to an old channel. The old tab shows a badge and the filtered all tab does not.

Validation that ran:

./gradlew spotlessApply detekt apiDump
:stream-chat-android-client:testDebugUnitTest and :stream-chat-android-compose:testDebugUnitTest
E2E locally against the mock branch, one test at a time: the 5 new FilteredGroupedChannelListTests and the 7 GroupedChannelListTests pass. Breaking the filtered badge or the local filter on purpose makes the matching new tests fail.

Summary by CodeRabbit

New Features
- Grouped channel queries now support per-group filters and sorting, including ordering by recent channel activity.
- Filtered grouped lists update as channels change, and cached filters and sorting are restored when loading offline data.
Bug Fixes
- Unread badges now reflect channels matching each group’s filter, preserve counts for groups not included in updates, and clear appropriately when all channels are marked read.

📝 Walkthrough

Grouped channel queries now accept filters for individual groups and an optional shared sort order. The client sends these options in requests, stores them in grouped query state, and applies filters and sorting to displayed channels and event routing. The change also updates filtered-group unread counts, restores grouped options from cached queries, and performs recovery requests by sort order. Sample screens and tests cover filtered grouped lists, channel activity, and unread badges.

Priority: ➖ Normal

Merge Risk: 🔵 Low · up to 8ecf0

The grouped filter feature looks sound, with a few minor edge cases to tidy up. The new end-to-end tests depend on a separate mock-server change that has not merged, so they may fail in default CI runs until that lands.

_{I’m a rabbit with filters tucked neat in my pack,
Sorting fresh channels along every track.
Old ones hop out when their dates drift away,
New messages bring them right back into play.
Unread badges count what the filters reveal,
I thump my paws at this grouped-channel wheel!}

…annel queries GroupedChannelsGroupQuery gets an optional filter, sent as the group's filter_conditions, and queryGroupedChannels gets an overload with a sort. The filter and sort are kept in the group's config and cached spec, so load more, reconnect and an offline start use them again. Channel events are checked against the group's filter, and a check every minute hides channels that pass their query_timestamp cutoff. The local query_timestamp is the latest of lastUpdated and the custom touched_at date. A filtered group's unread badge is now counted on the device: the unread channels the server counted that are not loaded, plus the loaded channels that are shown and unread. Grouped unread counts from events are merged into the current counts instead of replacing them. The grouped request models are regenerated with the sort and filter_conditions fields.

GroupedChannelsActivity gets a filtered mode, opened through InitTestActivity.FilteredGroupedChannels. It queries the groups with per-group filters, a 7 day query_timestamp cutoff and the query_timestamp sort. BackendRobot can seed channel ages and ParticipantRobot can touch a channel. FilteredGroupedChannelListTests covers the filtered tabs, a channel entering a filtered tab on a new message or touched_at, the filtered badge and mark all read.

… grouped e2e tests The mark all read test now starts with more unread channels than one page, so the filtered badges count channels that are not loaded and mark all read has to clear them. The touch test checks that the touched channel moves to the top. StreamDateFormatter.parse is internal again, since its only caller is in the same module.

A cutoff like -7d or now-0d is rejected by the backend. It no longer becomes a local cutoff in the future or at the current time, so the server decides.
