feat(mobile): a track goes on while the app is out of sight, through a foreground service (#1902) - #2024
Phase 3 of #1902: background tracking, a foreground service on Android. Stacked on #2022 (the track itself).
Platform: Platform::keep_locating(on) keeps positions coming while the app is out of sight, or lets them stop there again. RustGisApp::keep_locating is what the interface wants; the touch interface sets it while a track is being recorded, and the Android shell follows it, as it does locate.
Android (TrackService.java, new): a foreground service of the location type that does no work of its own. While it runs, the activity's location listener keeps receiving positions after onStop (which no longer stops them then), and they wait in the activity's events until the app is back and takes them all, through RustGisApp::fixes (feat(mobile): average the device's positions, and record a track (#1902) #2022), into the track. Its ongoing notice, "RustGIS is recording a track", brings the app back when tapped. The manifest declares the service and the FOREGROUND_SERVICE, FOREGROUND_SERVICE_LOCATION and POST_NOTIFICATIONS permissions.
Notifications (Android 13 and later): the first background track asks for leave to show them. A notice posted before the leave was given isn't shown, so the service posts it again once given; refused, the service runs without a visible notice. A service Android refuses is said in the window.
Never silent: past 200,000 waiting events (two days of a position a second), the oldest go, and the app says how many positions were dropped.
Not in this pull request
Keeping the track if the app is ended (swiped away) or the system ends its process: the service is START_NOT_STICKY, and the track lives in the app's memory.
iOS's background location mode (phase 4).
Testing
cargo test -p rustgis-ui-touch (23 tests): keep_locating is on while a track is recorded and off once it stops.
Workspace clippy (-D warnings), cargo xtask layers, the wasm build and Android clippy pass. The full test suite was not run locally.
On the Android 15 emulator (x86_64), with positions sent by adb emu geo fix: Record a Track started TrackService (dumpsys: isForeground=true, location type) and asked for leave to show notifications; after Home, six positions sent with the app out of sight were all in the track when the app came back. The first run showed the notice missing when the leave was given after the service started; with the fix, the notice appears in the shade, tapping it brings the app back with the three positions sent meanwhile, and Stop ends the service.
Not tested: a real phone with the screen off for a long time, a device's battery saver, Android 8 to 12.
Location averaging and track recording can continue while the app is out of sight when tracking is active.
On Android 13 and later, background tracking may require notification permission.
Improvements
Track history now retains up to 200,000 positions—more than two days at one position per second. When the limit is reached, the oldest positions are discarded.
Background tracking stops if the app process or activity ends.
The app now requests continued location updates while a track is recorded, using an Android foreground location service. The Android event queue and app position history retain up to 200,000 entries; the queue drops older events when full and reports the dropped count.

Summary
Keep-locating control and platform bridge crates/engine/src/platform.rs, crates/ui-egui/src/lib.rs, crates/ui-touch/src/lib.rs, apps/rustgis-mobile/src/lib.rs, apps/rustgis-mobile/src/phone.rs
The touch interface sets keep_locating when positioning is active and a track is recorded. The app forwards changes through the Platform interface to Android.
The manifest declares the foreground-service permissions and service. MainActivity handles permission requests and service lifecycle events. TrackService creates a foreground notification and starts as a location foreground service on supported Android versions.
Bounded position event queue apps/rustgis-mobile/java/org/rustgis/mobile/MainActivity.java, crates/ui-egui/src/lib.rs, crates/ui-touch/src/track.rs, apps/rustgis-mobile/README.md
The event queue drops its oldest entry when it reaches 200,000 entries and reports the number dropped. The app position limit is also 200,000. The README describes background track recording, notification permissions, and service termination behavior.
If a user switches to the desktop interface while recording, background location and the recording notification may keep running after the track has stopped. This is a battery and privacy concern and should be fixed before merge. The README also overstates background averaging, which only continues while a track is recording.

Explanation
The title names the main change: a background track that keeps recording while the app is out of sight, implemented through an Android foreground service. The raw summary and objectives confirm this is the primary change. The title is 97 characters, which is long, and it includes the issue reference, but it remains specific and descriptive.
Full details: Description check
Explanation
The description follows the repository template. It has Summary, Testing, UI evidence, and Related issue sections. The Summary explains the platform, Android service, notification, and dropped-position behavior, and it lists exclusions. Testing lists the commands run, the emulator steps, and what was not tested. The UI evidence section is required when UI changes are visible. The author attached three screenshots in a comment but left the template's 'No visible UI change.' line in place, which conflicts with the screenshots and the notification UI. The template line was not replaced, so the section does not match the change. Related issue is filled in.
Resolution
Replace the 'No visible UI change.' line in the UI evidence section with the before and after screenshots, or at least the after-only screenshot of the notification and the track window. The author's comment says three screenshots were attached, but the PR description itself does not include them. Attach the images to the description, not only to a comment.

Thanks for using CodeRabbit! It's free for OSS, and your support helps us grow. If you like it, consider giving us a shout-out.
A rabbit taps the track to start, While hidden paths still feed the chart. Two hundred thousand spots can stay, The oldest hops when full, away. A notice shines through night and dew, Then home the gathered points come through.
I found no correctness, crash, security, or silent-data-loss bugs in the changed code. I checked the Android lifecycle (onStop, onStart, onDestroy, rotation via configChanges), the permission flow, the JNI signature, the Platform trait's single implementor, minSdk 26 against the API 26 calls, and the touch UI's Hide path, which stops the track before it turns location off. There were no earlier review threads, so nothing was skipped as already raised.
Bugs
None found.
Security
None found.
Performance
crates/ui-touch/src/lib.rs:75: the new track::field(&ctx) read clones the whole track on every frame, and line 79 already does the same. Medium confidence. (Inline comment posted.)
apps/rustgis-mobile/java/org/rustgis/mobile/MainActivity.java:432: ArrayList.remove(0) is O(n) once the 200,000-event cap is reached. Low severity. (Inline comment posted.)
Quality
apps/rustgis-mobile/README.md:55: the line is about 130 characters, longer than the surrounding wrap. Nit, high confidence.
TrackService.java:37: the notification title and text are English literals. The Java side has no tl! path, and the existing Java messages are also English, so this matches current practice. Nit, medium confidence.
AGENTS.md
Checked the rules on crashes, silent loss, background work, translation, layering, and the wasm build. The changed Rust code has no unwrap or expect, and the new trait method has one implementor, so the wasm and layering rules are not affected.
The notification text is user-visible but not wrapped for translation. This is the same gap as the existing Java strings, so I treat it as a note rather than a violation. Low confidence.
Nothing in this review was rated as a blocking defect. The two inline comments are the items worth addressing before merge; the rest can wait for the release quality pass.
Change size
Compared with feat/mobile-track (merge base 6b24332 to PR head a979649).
Android-initiated stops (location off, permission revoked, no provider) leave the track recording with positioning off. keep_locating stays true, so TrackService keeps running with its "Positions are kept" notice and no positions. Suggested fix: app.locate && track.is_some() in crates/ui-touch/src/lib.rs:83. (medium, ~60%)
The startForegroundService catch in the permission-result path (MainActivity.java:129) says only that the notice can't be shown, and leaves keepLocating true. The service never started, so positions out of sight aren't kept. (medium, ~50%)
Timing: keep_locating reaches Java only on the next frame. A Record or Stop tapped right before Home can leave the service state wrong until the app returns. Requesting a repaint on change would fix it. (low, ~35%)
Security
None found. Input from the Android side is bounded, the results array is checked, and the new JNI calls catch RuntimeException.
Performance
On return, takeEvents can hand up to 200,000 lines across JNI and parse them in one frame on the UI thread. Not a regression, but worth a look on a long track. (low)
Quality
The comment at apps/rustgis-mobile/src/lib.rs:150 now sits above the keep_locating block instead of the locate block.
apps/rustgis-mobile/README.md line 47 runs past the 100-column wrap.
Notice title, body and channel name in TrackService.java are English literals. Java has no tl!, and the existing Java messages are English too, so this may need a catalog path later. (low)
AGENTS.md
Never crash, never silent, the wasm build and the layering rule are not affected: the trait change has one implementor (Phone), and the Java side never panics on the new paths.
The "Never hold the window" rule covers desktop, so the Android event drain is not a violation.
Checked and fine: minSdk 26 covers the notification and service APIs; ServiceInfo is guarded by SDK 29; configChanges means rotation doesn't reach onDestroy; the events deque and its dropped accounting are correct; onStop no longer stops positioning while the track runs; onStart doesn't register a second listener.
Earlier concerns left alone: 2. Both were already raised and fixed (track::field clone, ArrayList.remove(0)).
Change size
Compared with feat/mobile-track (merge base d47bfcd to PR head 8caa67e), the whole PR.
Bugs. No confirmed bugs. The earlier threads (the keepLocating start order, the stopped() cleanup, the failed-restart path, and the app.locate && track gating) are all present in this head and read correctly.
Low confidence (~30%): a TrackService refusal reaches Rust only through takeEvents, which runs only on a frame. If the user goes Home before a frame runs, the listener stays registered out of sight with no service. Inline comment posted on MainActivity.java:235.
Low confidence (~25%): onDestroy now stops the service. If the activity is destroyed while the process lives mid-track, the Rust mirror still says "keeping," so nothing re-sends the request. This extends a locate desync that already exists. Inline comment posted on MainActivity.java:328.
Security. Nothing found. Event text is built from fixed strings and exception messages, and Event::parse joins the tail fields, so tabs are safe.
Performance.
Low confidence (~35%): up to 200,000 events are joined into one string and parsed in one UI-thread frame on return. Inline comment posted on MainActivity.java:390.
Checked and fine: track::take removes the state from egui memory before pushing, so Arc::make_mut appends in place.
Quality. Nothing worth raising beyond the nits below.
AGENTS.md.
Never crash and never silent: the new paths report through add("failed…"), and dropped positions get a count. Both are satisfied.
Platform: only Phone implements Platform, so the new required trait method compiles. minSdk is 26, so the NotificationChannel and two-argument Notification.Builder calls are safe.
Not a regression: the new Java-side user-visible strings ("RustGIS is recording a track", the "can't be kept" messages) bypass tl!/i18n. There is no translation path on the Java side, and the existing Java messages already do the same.
Nits, grouped and not posted inline: README line 47 runs past 100 columns; e.getMessage() can be null and would then show as "null".
Prior concerns: I left alone 10 earlier threads because they are resolved and the code they point at is fixed in this head. None of the three findings above repeats one of them.
Change size
Compared with feat/mobile-track (merge base 8a2c778 to PR head 68c925c).
- Tapping Edit keeps the vertices drawn so far in Add, instead of dropping them without a word; they are drawn only while Add is on.
- Move Here and Add After refuse, and say why, a place on the vertex next to the picked one (a snapped cross lands there), which would make an edge of no length; tested both ways.
- The edited feature's shape is borrowed, not cloned, where it is drawn and checked each frame; status lists the vertices once; snapping is looked for again only when the cross, the zoom, the vertex being moved or the project changed.
- A track that can't be added (editing or the layer refused it) is kept being recorded and said, so Stop tries again instead of losing its positions; the desktop interface isn't switched to while it is kept; tested.
- Positions dropped past FIXES_KEPT are counted and said when a track or an average missed them; tested.
- The More sheet is sized for the track's row while a track is recorded with positioning off.
- Typing in a sheet the keyboard leaves short (a phone held sideways), the rows above the capture fields step aside until the keyboard goes, so the field stays in sight.
- TrackService's refusal reaches the activity at once: it stops keeping positions out of sight then, and stops asking for them if already out of sight, not at the next frame.
- The README says Android ending the activity ends a track too.
Track loses the positions the PR says it keeps (~80%). The Java cap is 200,000 events, but when the app returns, all waiting events reach report_position in one frame, and FIXES_KEPT is 86,400. track::take runs after the whole batch, so the oldest positions beyond 86,400 are dropped. The drop is reported through fixes_dropped, so it isn't silent, but the README and PR text ("takes them all into the track", two days kept) don't hold. Posted inline at MainActivity.java:35.
Security
None found. TrackService is exported="false", the JNI entry points are not exposed to other apps, and the notification text is constant.
Performance
Nothing new. The one-frame parse of up to 200k events was already raised in an earlier thread and left for the quality pass.
Quality
README lines 52–62 (the keep_locating sentence in "The phone, from Rust" and the new track paragraph) run past the file's line width. Nit.
The dropped-events notice in takeEvents says "positions", but add() counts every event kind. In practice only positions can fill the queue, so this is wording only. Low confidence (~20%).
AGENTS.md
New user-visible English strings in Java ("Positions can't be kept while RustGIS is out of sight…", the dropped-positions notice) bypass tl!. The existing Java strings do the same, so this extends a gap rather than starting one. Low confidence (~35%).
The new Rust and Java paths carry the notices the rules require. The new test covers the flag. The FIXES_KEPT gap above is the one that needs a fix.
Already raised, left alone (9 threads)
Rust keeping mirror drifting after a service refusal. The author's reply explains the design, and I have no new evidence against it.
Timing of the repaint, the keep_locating ordering, the onDestroy service stop, the startForegroundService catch, and the track::field clone cost. All were fixed or answered in the thread.
Change size
Compared against feat/mobile-track (merge base 94e25ce to PR head 7ca873d), the whole PR.
- A track with breaks where the device's position was off is stored in parts, one for each run, not joined across the gap; the overlay breaks there too, and the parts and any position alone between breaks are said; tested.
- A position older than the last kept is left out and counted, so the line doesn't double back; tested.
- The track overlay starts a new run where consecutive positions are across the antimeridian.
- `finish` says in its doc comment why it runs on the window's thread.
- The kept-track test checks that the reason the layer refused it is said before that it is kept.
- A track whose positions are each alone between breaks says that is why it wasn't added, and how many positions were left out, instead of "fewer than two positions"; tested.
- FIXES_KEPT is now 200,000, as many positions as the activity keeps out of sight (MOST_EVENTS), so a two-day batch handed over on coming back goes whole into the track, as the README says.

Bug (confidence ~55%), re-raising the earlier timing thread because the reply doesn't cover this case.request_repaint fires only when keep changes, but keep is computed here, before the bottom bar (Stop and Record, lines 94–120), the track banner's Stop, and the More sheet (Hide My Position, lines 155–163). start_track and stop_track don't request a repaint either. So after a tap that changes the state in the same frame, app.keep_locating is stale for that frame. If the user presses Home before any later frame runs, keepLocating(false) never reaches Java: the service and its notice keep running out of sight after Stop (and after Hide), with no track being recorded.
Suggested fix: move this block (lines 86–92) to the end of chrome, after the sheet, so every tap in the frame is seen before the frame ends. The existing request_repaint then guarantees the next frame that sends the change.
The reason will be displayed to describe this comment to others. Learn more.
Bug (confidence ~25%), silent loss of a refusal reason.refusal is a volatile static read here and cleared on the next line, which is two separate steps. TrackService.onStartCommand (main thread) can set refusal between them. The clear then drops the new reason, and its "failed" event is never added, so the reason is lost while keepLocatingRefused() still runs. The rule against silent loss applies here.
Suggested fix: make refusal an AtomicReference<String> and take it with a single getAndSet(null), so a refusal is either taken now or left for the next call.
I read the full 531-line diff, the staged AGENTS.md, the existing review threads, and the surrounding code in MainActivity.java, TrackService.java, apps/rustgis-mobile/src/lib.rs, phone.rs, crates/ui-touch/src/lib.rs and track.rs. I did not compile or run anything; this run had no build or test tools.
Bugs
Same-frame taps are not seen before the frame ends (crates/ui-touch/src/lib.rs:88, confidence ~55%). This re-raises the earlier timing thread. The maintainer's request_repaint fix only fires when keep changes, but keep is computed before the bottom bar (Stop and Record), the track banner's Stop, and the More sheet (Hide My Position). None of those paths requests a repaint. If Home comes before a later frame, the service and notice keep running after Stop or Hide. Moving the block to the end of chrome fixes it. Posted inline.
A refusal reason can be dropped (MainActivity.java:395, confidence ~25%). refusal is read and then cleared in two steps, so a refusal set in between is lost, along with its "failed" event. Posted inline; AtomicReference.getAndSet(null) closes the window.
Security
None found.
Performance
Nothing new. The large event string and the per-frame parse were already raised and deferred to the release quality pass.
Quality
The drop notice says "positions were dropped", but dropped counts every evicted event, including failed or stopped (MainActivity.java, takeEvents). Low confidence, ~30%. Wording only.
apps/rustgis-mobile/README.md: the rewritten paragraph around the Platform list runs well past the paragraph's wrap width, and the new "Ending the app…" sentence is one very long line. Nit, for the release quality pass.
AGENTS.md
The PR adds a visible notification, but its description has no screenshot. The rule asks for one on any visible change. Confidence ~40%.
Otherwise the change follows the guidelines I checked: no unwrap/expect, refusals and dropped events are reported through failed events, the new required Platform::keep_locating has only one implementor (Phone), and the Rust keepLocating JNI signature matches.
Prior threads: I left 13 earlier concerns alone (already answered or resolved; none still present in new code). I re-raised one, the same-frame repaint timing, with the new evidence. The rest of the batch-size and performance concerns were deferred by the maintainer.
The reason will be displayed to describe this comment to others. Learn more.
Bug (confidence ~55%): the cap holds about 28 hours at the rate positions arrive, not "two days of a position a second".startLocating asks both the GPS and the network provider for a fix every 1000 ms (lines 309–319). With both delivering, add() gets about two position events a second, so 200,000 events last about 27.8 hours. The same "two days" claim is in FIXES_KEPT's doc (crates/ui-egui/src/lib.rs), the README and the PR description.
The oldest positions still go, with the notice, so nothing is silent. But a track kept out of sight for longer than about 28 hours loses its start, which contradicts the documented guarantee.
Either raise the cap (FIXES_KEPT has to match it, since that is what keeps a batch whole), or state the rate that is actually delivered.
Capacity claim is wrong at two fixes a second (~55%, inline on MainActivity.java:38). GPS and network are both requested every 1000 ms, so the 200,000-event cap holds about 28 hours, not two days. The oldest positions are still dropped with a notice, so this is not silent. The same claim appears in FIXES_KEPT's doc, the README and the PR description.
Security
None found in the changed lines.
Performance
Nothing new. The 200,000-event takeEvents join and parse on the UI thread was raised earlier and deferred to the release quality pass.
Quality
e.getMessage() can be null, which puts the literal text "null" into the failed messages (MainActivity.java lines ~137, 236; TrackService.java ~343). Low confidence on how often it matters.
The dropped-events notice says "positions", but add() drops whichever event is oldest, so a stopped or failed line could go under that wording. Low.
java.util.ArrayDeque is fully qualified inline; importing it would match the file's style. Nit.
README.md lines ~47–48 and ~62 run past the file's usual wrap width. Nit.
AGENTS.md
The PR adds a visible notice in the Android shade, and the rules say visible changes need screenshots. The PR body describes the emulator check but attaches no image. Medium confidence.
Left alone (already raised in earlier threads, code unchanged)
ui-touch/src/lib.rs:88: keep_locating is computed before the bar and sheet, so a tap that changes state in the same frame can leave it stale until another frame runs. Unresolved and not outdated.
MainActivity.javatakeEvents: the refusal read and clear are two separate steps, so a refusal can be lost in a race. Unresolved and not outdated.
Answered or resolved and not re-raised: the Rust keeping mirror, the stopped() and onDestroy paths, the FIXES_KEPT mismatch, the track clone cost, the ArrayList eviction, and the startForegroundService and permission-order points. I agree with the author's replies on these.
I checked minSdkVersion (26), so the notification calls need no guard. Only phone.rs implements Platform, so the new trait method breaks no other implementor. The refusal, dropped and keepLocating state is handled on the main thread as the comments say.

Clear keep_locating when the touch interface stops owning the track.
While recording, select “Use the Desktop Interface”. This code computes keep=true before more() stops the track and sets app.chrome=None. Later frames no longer call this code, so app.keep_locating stays true. The mobile bridge never sends false, and MainActivity.onStop() keeps background positioning and the recording notification active.
Clear the request when the interface switch succeeds, or synchronize it outside the removable touch callback. Add a test that switches interfaces while recording and checks that the request becomes false.

Summary
Phase 3 of #1902: background tracking, a foreground service on Android. Stacked on #2022 (the track itself).
Platform::keep_locating(on)keeps positions coming while the app is out of sight, or lets them stop there again.RustGisApp::keep_locatingis what the interface wants; the touch interface sets it while a track is being recorded, and the Android shell follows it, as it doeslocate.TrackService.java, new): a foreground service of the location type that does no work of its own. While it runs, the activity's location listener keeps receiving positions afteronStop(which no longer stops them then), and they wait in the activity's events until the app is back and takes them all, throughRustGisApp::fixes(feat(mobile): average the device's positions, and record a track (#1902) #2022), into the track. Its ongoing notice, "RustGIS is recording a track", brings the app back when tapped. The manifest declares the service and theFOREGROUND_SERVICE,FOREGROUND_SERVICE_LOCATIONandPOST_NOTIFICATIONSpermissions.Not in this pull request

The full test suite was not run locally.adb emu geo fix: Record a Track startedTrackService(dumpsys:isForeground=true, location type) and asked for leave to show notifications; after Home, six positions sent with the app out of sight were all in the track when the app came back. The first run showed the notice missing when the leave was given after the service started; with the fix, the notice appears in the shade, tapping it brings the app back with the three positions sent meanwhile, and Stop ends the service.Related issue
