Enroll SwipeRevealLayout.kt in the file-level Spotless ratchet ahead of the ADFA-5487 functional change, so the whole-file reindent to tabs is not reviewer noise in a behavioral commit. ktlint changes only: import ordering, parameter list wrapping, and `return x` to expression-body conversions.

RightDragCallback.tryCaptureView returned an unconditional `true`, with the intended check commented out as `// child.id == R.id.right_drawer_sidebar` -- an id that exists nowhere in the project. There is no right drawer in activity_editor.xml, so the helper had no legitimate target but captured whichever child sat under a horizontal drag and offset it sideways. Two consequences, both fixed by never capturing: - onViewPositionChanged pushed that horizontal travel straight to dragListener.onDragProgress, bypassing the layout's own onDragProgress. BaseEditorActivity.onSwipeRevealDragProgress then animated the content card's corner interpolation and top padding as if the vertical reveal were being dragged. - onInterceptTouchEvent returns `isLeft || isRight || isVertical`, so the layout stole horizontal gestures from its children. A horizontally scrolling child raced this helper across the same ViewConfiguration touch slop, making the outcome nondeterministic. ADFA-5487 puts a ViewPager2 carousel in exactly that position, which is how this surfaced. No edge tracking is configured, so with capture refused the helper is inert. The callback is left in place as the attachment point for a right drawer, should one ever be added. Verified: :app:compileV8DebugKotlin.

BaseEditorActivity drove the memory chart by reaching into binding.memUsageView.chart from six sites and mutating entry.y against a pidToDatasetIdxMap that only resetMemUsageChart() populated. That works only while exactly one chart view exists for the activity's lifetime. ADFA-5487 makes the chart one page of a carousel, where the view can be unbound, recycled, or created long after watching began. MemoryUsageChartRenderer owns the chart wiring instead and holds no sample state: MemoryUsageWatcher already keeps each process's usageHistory ring buffer, so the renderer can rebuild a complete chart from getMemoryUsages() at any time. attach/detach are independent of the data. Two behaviour changes, both deliberate: - attach() renders the full existing history. resetMemUsageChart() used to seed every entry with 0f and wait a tick for real values, which a carousel page bound mid-session would show as a flat line. - onUsagesChanged() rebuilds when the incoming processes no longer match the chart's datasets, instead of logging "No dataset found for process" and dropping that process's samples. This was already reachable without a carousel: ProjectHandlerActivity watches the Gradle Tooling process and then calls resetMemUsageChart(), so any sample arriving between those two lines was discarded. The once-a-second path still mutates the existing Entry objects in place and allocates nothing; the rebuild is the exception, not the rule. The renderer relies on ChartData.getDataSetByIndex returning null for an out-of-range index, which the shipped AndroidChart 3.1.0.21 bytecode confirms (null for index < 0 or >= size) -- the same guard the previous code depended on. Sites swept: all six chart call sites in BaseEditorActivity, both resetMemUsageChart() callers in ProjectHandlerActivity (unchanged, the method keeps its signature), and the now-dead pidToDatasetIdxMap/editorSurfaceContainerBackground members and their imports. No other module referenced either. Tests: 5 new Robolectric tests in MemoryUsageChartRendererTest. Verified they fail without the fix -- reverting the two behaviour changes fails "attach renders the complete existing history", "attach after detach renders the history into the new chart" (all-zero entries) and "onUsagesChanged rebuilds when a process starts being watched" (dataSetCount stays 1), each for the reason it is named for. The in-place-update test passes either way by design, since that path is unchanged. Verified: :app:compileV8DebugKotlin, :app:testV8DebugUnitTest (MemoryUsageChartRendererTest, 5/5). No UI change, so no font-scale check yet; that lands with the carousel.

The chart at the top of the editor (revealed by dragging the app bar
down) is now a ViewPager2 carousel. Page 1 is the memory chart, still
the default; page 2 is the Code On The Go brand mark, a placeholder
until there is a real second metric.
MetricsCarouselAdapter takes its page list as a constructor argument, so
the follow-up tickets (a TrafficStats network chart, and plugin-
contributed displays) add pages rather than change this class. The chart
page attaches MemoryUsageChartRenderer on bind and detaches on recycle;
because the renderer rebuilds from MemoryUsageWatcher's history, swiping
away and back shows the full 30-sample series rather than a flat line.
Layout notes:
- layout_mem_usage.xml stays a single view. SwipeRevealLayout asserts
childCount == 2 and indexes its children positionally, so the include
cannot gain a sibling; the pager and indicator live inside it.
- The status-bar inset now applies to the pager rather than the chart,
so MemoryUsageChartRenderer.setTopMargin (a shim from the previous
commit, when the activity owned the only chart) is gone. It gains
detachIfAttached, which a recycling container needs: RecyclerView can
bind a replacement view before recycling the one it replaced, and an
unconditional detach would then drop the new chart.
- editor_mem_usage_view_height goes 200dp -> 248dp. The indicator is new
chrome, so the container grows by its 48dp rather than the chart
shrinking. This is a visible change beyond the ticket's literal scope;
it is here because of the touch-target point below.
- TabLayout has no dot mode, so each tab's background is a selector and
the sliding indicator is suppressed. The oval needs a sized, centred
layer-list item: a tab background is stretched to fill the tab, which
ignores a bare shape's <size> and renders an oval as tall as the whole
row. The active dot differs in both size and colour because several of
this app's themes resolve colorPrimary to a grey indistinguishable
from colorOutline (measured on device: #AAAAAA vs #8F9099).
A left-to-right swipe cannot page backwards: that gesture opens the
navigation drawer, which is documented app behaviour ("To view the file
tree and project options, swipe from left to right", shown in the
editor's own onboarding text). InterceptableDrawerLayout's
findScrollingChild starts at index 1 and so never examines DrawerLayout's
content child, which is consistent with that intent. Backward navigation
is therefore by tapping the indicator, which makes the dots a primary
control rather than decoration -- hence real 48dp touch targets,
measured on device at 48x48dp (168x168px at 560dpi), each carrying a
"Metric N of 2" content description.
androidx.viewpager2 is declared explicitly. It was already on the
compile classpath transitively and pinned to the same 1.1.0-beta02 the
version catalog names, so this adds no new dependency; it just stops a
compile-time use depending on another library's graph.
Verified on a Pixel 6 Pro (arm64), v8 debug:
- Both pages render; swipe forward and tap-to-navigate both directions.
- Returning to page 1 shows the complete history for both watched
processes, including a Gradle Tooling process that started while the
carousel was open (the rebuild path from the previous commit).
- Font scale 1.0 and 2.0: no clipping, no overlap, status bar clear,
touch targets unchanged. MPAndroidChart sizes its own text in pixels
so the chart labels do not grow with font scale -- pre-existing, and
worth a follow-up for low-vision users.
- Landscape: renders correctly, nothing clipped.
- :app:testV8DebugUnitTest for ui/activities/fragments: 41 tests green.

The carousel could only page forwards. A left-to-right swipe opened the navigation drawer instead, so going back needed a tap on the indicator dots, which in turn forced them to be 48dp touch targets. Two mechanisms claim that gesture, and each needs its own answer: - View-hierarchy interceptors. MetricsCarouselLayout, the new root of layout_mem_usage.xml, calls requestDisallowInterceptTouchEvent on its ancestors on ACTION_DOWN. That propagates the whole way up, so any ancestor ViewGroup is out of the way for the rest of the gesture, and only for gestures starting inside this strip. - The editor's activity-level GestureDetector, run from dispatchTouchEvent. It never calls onInterceptTouchEvent, so no disallow-intercept can stop it; this was in fact the one opening the drawer, confirmed on device. isTouchOnMetricsCarousel excludes the carousel's bounds the same way isTouchOnBottomSheetTabs already excludes the bottom-sheet tab strip. The exclusion is gated on swipeReveal.dragProgress > 0. The carousel is laid out at the top of the reveal even while the content card covers it, and siblings do not clip each other, so getGlobalVisibleRect reports it visible either way; without the gate the drawer gesture would have gone dead over the top of a closed editor. The vertical reveal drag is unaffected: SwipeRevealLayout only captures a vertical drag whose touch-down landed in its drag handle (the app bar), never in this strip. With swipe working both ways the dots are a status indicator rather than a control, so they no longer need 48dp targets or accessibility nodes of their own -- ViewPager2 already reports page position, and each page carries its own content description. Touches on the indicator are swallowed so the dots cannot act as tabs, while TabLayoutMediator still tracks the selected page. The row drops 48dp -> 20dp and, with the panel kept at 248dp, that space goes to the chart: the plot area grows from 135dp to 187dp. The now-unused metrics_carousel_page string is removed. Verified on a Pixel 6 Pro (arm64), v8 debug: - Paging forward and backward by swipe, portrait and landscape. - Returning to page 1 still shows full history for both watched processes. - Drawer gesture unaffected: still opens from a rightward fling outside the carousel while the reveal is open, and from one over the region the carousel occupies once the reveal is closed. - Font scale 1.0 and 2.0: geometry is dp-only and unchanged (pager and indicator bounds identical at both), nothing clipped, status bar clear. - :app:testV8DebugUnitTest for ui/activities/fragments: 41 tests green.

Dots said which page you were on but not what it was. A metrics
carousel is a set of different displays, so naming the current one
carries more information in the same space: "Memory usage" rather than
two dots.
MetricsPage gains a title, so a page names itself and the follow-up
tickets (network chart, plugin-contributed pages) supply one as a
matter of course. A ViewPager2.OnPageChangeCallback drives the label;
it is unregistered alongside the adapter in preDestroy. The callback
does not fire for the page the carousel opens on, so the initial title
is set explicitly.
The title is sp text, unlike the dp-sized dots, so the layout had to
change shape: the title is wrap_content and the pager takes whatever
height is left. At 2x font scale the title grows from 22dp to 35dp and
the chart gives up that space, rather than the label clipping or the
panel changing height. No maxLines or ellipsize -- a long title wraps
and the chart absorbs it, which is the right failure mode for text that
is not disposable.
This drops the TabLayout, the dot selector drawable, its four dimens,
and the touch-swallowing needed to stop dots acting as tabs. The dots'
theme problem goes with them: the active dot needed to differ in both
size and colour because several themes resolve colorPrimary to a grey
indistinguishable from colorOutline.
Trade-off: a title does not show that further pages exist, which dots
did. Worth revisiting if the carousel grows past a handful of pages; at
two, swiping finds the second one and the title then says what it is.
Verified on a Pixel 6 Pro (arm64), v8 debug:
- Titles track the page ("Memory usage", "Code On The Go"); paging both
directions still works and page 1 still returns with full history.
- Font scale 1.0 and 2.0, measured on a cold start: title 22dp -> 35dp,
pager 185dp -> 171dp, panel 248dp throughout, nothing clipped.
EditorActivityKt declares fontScale in configChanges, so it is not
recreated on a font-scale change -- a warm relaunch reports stale
geometry and the app must be force-stopped first to measure this.
- :app:testV8DebugUnitTest for ui/activities/fragments: 41 tests green.

Three defects raised in review of ADFA-5487/5489, all in the same few lines and all present in both watchers. stopWatching() could not stop the sampler. The loop was launched with `launch(context = SupervisorJob() + dispatcher)`, which gives the coroutine its own parent job, so the watcher's scope could not cancel it: it ran on until it next observed the `watching` flag, and it spends almost all of its time asleep in `delay(updateInterval)`. Stop and start inside that window and the old loop woke up, saw the flag set again, and carried on beside the new one -- two samplers writing history and notifying the chart. The window is as wide as the interval, which ADFA-5486 made configurable up to sixty seconds. The job is now stored and cancelled. An exception ended sampling permanently. A throw anywhere in the body killed the coroutine while `watching` stayed true, so every later startWatching() was refused as "already watching" and the chart silently stopped updating for the rest of the session. A misbehaving listener was enough. The body is guarded now: a sample is worth losing, the loop is not. CancellationException is rethrown so cancellation still works. The dispatcher was never closed. `newSingleThreadContext` holds a thread until closed, and nothing closed it. close() is separate from stopWatching() because the watcher is stopped and restarted across the editor's lifecycle; only the terminal teardown should give up the thread. MetricsViewModel.onCleared calls it. startWatching() also uses compareAndSet rather than a check followed by a set, so two callers cannot both pass the guard. Tests: 5 new lifecycle tests. Verified they fail without the fix, though the first one fails by hanging rather than by asserting -- with the loop unstoppable, runTest never drains the scheduler. That is the bug seen from the inside, and it is why each test now closes its watcher. Verified on a Pixel 6 Pro (arm64), v8 debug: chart samples continuously across a background/foreground cycle, no crashes, nothing logged from the new failure guard. 70 tests green across app ui/utils.

…5487) resetMemUsageChart() ran on two background threads. The renderer documents itself as UI-thread-only, and rebuild() clears and repopulates a non-thread-safe pid-to-dataset map that the once-a-second sample listener reads on the main thread. The tooling server's start callback arrives on its own thread and the metadata correction on a CompletableFuture completion thread, so either could interleave with a tick and plot one process's samples on another's line, or throw out of the entry loop. Both now post to the main thread. The process colour lookup could take the editor down, from a timer. It threw IllegalArgumentException for an unrecognised process name, which was survivable while only two explicit call sites reached it -- this PR routes it through the 1 Hz listener and through RecyclerView's bind pass. An unknown name now falls back to grey. It also moves to the companion: a bound reference to an activity method is handed to the renderer, which the adapter holds, and nothing in the function needs an activity. containsTouch compared window coordinates against screen coordinates. getGlobalVisibleRect reports the rect in window space -- ViewRootImpl intersects with the window and never offsets by its position on screen -- while rawX/rawY are screen coordinates. In split-screen or freeform the window origin is not zero, so the drawer gesture was dead over the carousel and live below it. Now uses getLocationOnScreen, the idiom SwipeRevealLayout.isTouchInDragHandle already used in this same file. The drawer fling was excluded over the whole strip even when the carousel could not use it. A left-to-right fling pages the carousel backwards, and the carousel opens on the first page, so on that page the gesture did nothing at all while the documented right-swipe drawer gesture stayed dead. The exclusion now applies only when there is a previous page, and only over the pager rather than the whole strip. The reveal drag relaid out a ViewPager2 every frame. The inset compensation moved from a chart view to the pager, so a margin change now re-measures the pager, its RecyclerView and every attached page on each frame of the drag. A translationY gives the same result for a pure vertical offset with no layout pass. The viewpager2 dependency pointed at 1.1.0-beta02 while the catalog's other alias for the same module is 1.0.0, so Gradle's conflict resolution upgraded the whole app classpath -- including appintro, compiled against 1.0.0 -- to a pre-release nobody chose. Now uses the stable alias. The brand strings duplicated app_name, were translatable, and had drifted to a different capitalisation of the product name. The title now uses app_name; the content description is one string, not translatable. Two claims in the diff were false and are now either true or gone: the in-place update path does not "allocate nothing" -- it reformats a legend label per series per tick -- and the byte-per-megabyte constant was defined twice, once in main and once in the test, so the test verified its own arithmetic rather than the renderer's. Two tests were strengthened. "onUsagesChanged after detach is a no-op" asserted nothing at all and passed with the guard deleted; it now snapshots the chart and asserts it is unchanged. And the branch production actually hits -- same process count, one pid swapped, which is what a tooling-server pid correction produces -- had no coverage, so correctness rested on getDataSetByIndex(-1) happening to return null.

No behaviour change. Both were provably unreachable and still ran on every touch event and every animation frame. LeftDragCallback.tryCaptureView required a child whose id is R.id.drawer_sidebar. The layout asserts childCount == 2 and indexes its children positionally -- the hidden content and the overlapping content -- and drawer_sidebar is a FragmentContainerView inside the NavigationView, not a child here, so it was never true. RightDragCallback.tryCaptureView already returned false unconditionally, having been narrowed earlier in this stack when it was found capturing whichever child sat under a horizontal drag. Yet onInterceptTouchEvent still asked both helpers whether to intercept, onTouchEvent still fed both every event, and computeScroll still settled both on every frame. Their onViewPositionChanged also reported horizontal travel to dragListener as though it were vertical reveal progress, which is exactly the kind of thing a reader trusts and then debugs the wrong way round. Gone with them: leftDragProgress and rightDragProgress, both unread. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

@jatezzz — a merge-order note on the two MEDIUMs you raised, plus a correction to what I told you in those threads. The ask: don't merge this one on its own. Both defects you found are fixed in #1785, not here. This is the only PR of the three that targets The correction. In both threads I offered to drop the changes from this PR instead, and priced it at "a rebase of the ten branches above it". That was wrong twice over, and the second half is what matters to your decision:
So if you would rather this PR were sound on its own, the If you are happy to review-and-merge the three as a unit, nothing needs to change and the note in the description is enough. |

…el (#1787) * feat: add a UID-level network traffic page to the metrics carousel Second page of the editor's metrics carousel (ADFA-5487) is now a live network traffic chart, replacing the brand-mark placeholder. Accounting is UID-level, as decided on the ticket: TrafficStats.getUidRxBytes / getUidTxBytes cover every process sharing the app's UID, so Gradle's downloads are included without any socket tagging -- the Gradle Tooling and daemon processes share it. There is deliberately no per-feature breakdown; the only two tagged sockets in the tree are the local documentation web server and the JDWP listener, neither of which is interesting here. The platform counters are cumulative since boot, so NetworkUsageWatcher records the delta between consecutive samples. Three cases the raw counters would get wrong: - The first sample only establishes a baseline and contributes 0. Otherwise the chart would open with a spike equal to everything the app had transferred since boot. - A counter that goes backwards (reboot, re-based accounting) records 0 rather than plotting negative traffic. - TrafficStats.UNSUPPORTED (-1), which some devices return, is detected once and latched, so -1 is never plotted as a byte count. getUsage() hands out copies rather than the live ring buffers, guarded by a lock. The renderer reads all 30 entries while the sampler thread appends, and MemoryUsageWatcher's equivalent has that race today. Axis, per the ticket's decisions: - Values are log10(bytes + 1). Traffic spans orders of magnitude -- a few hundred bytes of chatter next to a multi-megabyte download -- and a linear axis flattens all of it but the largest burst onto the baseline. MPAndroidChart has no logarithmic axis. - The + 1 floors zero, which is the common sample rather than an edge case: an idle IDE transfers nothing and log10(0) is negative infinity. A zero sample plots at exactly 0.0 and the line stays continuous. - Units are decimal (1 kB = 1000 B), not binary. This was not in the ticket and is a consequence of the log axis: on-device the first cut labelled the gridlines 9B / 99B / 999B / 9.8KB, because powers of ten divided by 1024 stop looking like decades. Decimal units label them 0B / 10B / 100B / 1.0kB, and are the convention for throughput. - Axis labels show 10^value rather than the exact inverse 10^value - 1, which would read 9B / 99B / 999B. One byte is not worth the confusion, and the legend carries the exact current figure. Zero is labelled exactly, since log10(0 + 1) really is 0. MetricsPage.Image and its layout go with the placeholder, having no remaining user; ADFA-5490 will define its own extension surface. The cogo_brand_mark drawable stays -- six other screens use it. Verified on a Pixel 6 Pro (arm64), v8 debug, over wifi with a real Gradle sync: - Both series track real traffic (peaks ~10kB/s against byte-level chatter, both legible on the one scale), idle periods sit flat on the 0B baseline, and the axis reads 0B / 10B / 100B / 1.0kB / 10.0kB. - Swiping to the memory page and back returns the full 30-sample history, so the page is recycling-safe like the memory one. - Font scale 1.0 and 2.0, measured on a cold start (EditorActivityKt declares fontScale in configChanges, so a warm relaunch reports stale geometry): title 22dp -> 35dp, pager 185dp -> 171dp, panel 248dp throughout, nothing clipped. - Landscape renders correctly, nothing clipped. - 16 new tests (7 watcher, 9 renderer); 80 tests green across app ui/utils/activities/fragments. ADFA-5489 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01QeW3M24yD6HNhEnbuNW7Hz * fix: label the network axis in whole units and rest zero on the baseline Two axis problems, one cosmetic and one a real rendering bug. Labels now read "10 kB" rather than "10.0kB". Gridlines sit on whole decades (granularity 1), so the mantissa is always exact and the decimal place carried no information. formatBytes takes the precision as an argument: none for axis labels, one place for the legend, where the figure is an arbitrary sample and the decimal does carry information. A space separates value from unit throughout. Zero now rests on the baseline. Two causes, both fixed: - The series were scaled against the wrong axis. LineDataSet defaults to axisDependency LEFT, and the labelled axis here is the right one, so the line was positioned by the disabled, auto-ranged left axis while the labels came from the right. The two only agree while both auto-range over the same data; pinning one made them disagree visibly -- an idle chart drew its zero line halfway up a plot whose baseline was labelled 0 B. - The range was not pinned. With every sample zero the data range is degenerate and the chart pads around it. applyAxisRange now fixes the minimum at 0 and the maximum at whole decades above the peak, with a floor of three decades so an idle chart keeps a sensible scale instead of collapsing onto a single value. Worth noting for review: the unit tests asserting axisMinimum and axisMaximum passed throughout, because the axis really was configured correctly -- the data simply was not drawn against it. Only the device showed it. There is now a test asserting the axis dependency of both series, which is the part that was untested. MemoryUsageChartRenderer has the same LEFT-dependency-with-RIGHT-labels shape and renders correctly, because it pins neither axis and both auto-range over the same data. Left alone. Verified on a Pixel 6 Pro (arm64), v8 debug: - Idle: both series rest exactly on the 0 B baseline, axis reads 0 B / 10 B / 100 B / 1 kB. - Under a Gradle sync: axis grows to 10 kB, peaks and zero-traffic troughs both legible, legend reads "212 B/s". - 49 tests green across app ui/utils, including four new ones covering the axis range, its growth across both series, whole-unit labels, and the axis dependency.

They were fixed, but on #1785 -- a later PR in the stack than the one that ships the bug. This PR is already approved and ahead of that one, so on its own it still carried all three. Moving the fix to where the defect lives. The scope had no parent Job and startWatching() supplied its own SupervisorJob per launch, so nothing the scope did could cancel the sampler. stopWatching() only lowered a flag the loop checks once per interval, and the loop spends nearly all its time in delay() -- up to 60s once ADFA-5486 makes the rate configurable. A stop and start inside that window left two loops appending to one buffer, splitting each delta between them. The scope now has a parent job, the launch is stored, and stopWatching() cancels it. Nothing caught exceptions inside the loop. An exception -- a misbehaving listener is enough -- ended the coroutine while `watching` stayed true, so every later startWatching() was refused as "already watching" and sampling was dead for the rest of the session. The body is wrapped, and CancellationException is rethrown so structured cancellation still works. The dedicated sampling thread was never released. close() is separate from stopWatching() on purpose: the editor stops and restarts the watcher across its lifecycle, and only the terminal teardown should give up the thread that newSingleThreadContext keeps alive. The activity's destroy path calls it. startWatching() now guards with compareAndSet rather than a read followed by a write, so two callers racing cannot each start a sampler. The watcher takes its dispatchers as parameters, matching MemoryUsageWatcher, so NetworkWatcherLifecycleTest can drive the loop on a virtual clock. Waiting on the wall clock is what hung the test executor the first time this was attempted. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01QeW3M24yD6HNhEnbuNW7Hz * fix(metrics): actually apply the sampler fix, and stop a failed test spinning The previous commit shipped the commit message for this fix without the fix. An interrupted command had reverted the watcher to its pre-fix shape for a negative check and was killed before it restored it, so what got committed was `launch(SupervisorJob() + dispatcher)` and a scope cancel that cannot reach the sampler -- the very defect being fixed. stopWatching() now cancels the stored job, as its own comment already claimed. That mistake did prove the tests: against the unfixed watcher NetworkWatcherLifecycleTest reported two samples per interval where one was expected, which is exactly the two-loop overlap the fix exists to prevent. The tests also gained the cleanup they should have had. Each body now closes its watcher in a finally. Without it a failed assertion skipped close(), left the sampling loop live, and runTest's trailing advanceUntilIdle advanced virtual time forever -- a synchronous spin no test timeout can interrupt, which pinned a core and took the Gradle task to its ten-minute limit with no output. CodeRabbit raised exactly this about the tests on #1785; the lesson had not been carried over here. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01QeW3M24yD6HNhEnbuNW7Hz * fix(metrics): re-baseline on resume, and stop sampling a device that cannot (ADFA-5489) Four review findings on the network watcher. A resume reported the whole gap as one interval. stopWatching() left lastRx and lastTx set, so the first sample afterwards took the delta against a counter read minutes earlier: background a Gradle download for three minutes and the legend read hundreds of MB/s while the axis stretched to match. The baseline is now dropped on stop, which is exactly what the null baseline already means elsewhere -- the next sample re-establishes it and contributes nothing. The baseline was also written outside the lock that clears it. sampleOnce wrote lastRx/lastTx on the sampler thread while clearHistory nulled them on the UI thread, so an interleaving could restore a pre-clear baseline and produce the same spike at the moment the user changed the sampling rate -- the failure the "cumulative baseline is dropped too" test exists to prevent, which it cannot see because it drives sampleOnce synchronously. listener was a plain var written by the UI thread and read by the sampler every tick, with no happens-before edge, so a null written in onPause could go unobserved and the sampler keep dispatching into a paused activity. Now @volatile, as isSupported on the same class already was for the same reason. A device whose counters are unsupported kept the loop running anyway. isSupported latched false and sampleOnce returned immediately, but every interval still snapshotted the buffers, hopped to the main thread and repainted the chart with data known to be permanently zero. The loop now ends, and clears the watching flag as it goes so isWatching does not claim a sampler that has stopped. Not fixed here, deliberately: the legend's "/s" suffix. It is accurate on this branch, where the interval is a constructor value fixed at one second. It only becomes wrong once ADFA-5486 makes the rate user-settable, and only that branch has the interval available to the renderer, so the fix belongs there.

Close networkUsageWatcher on every Activity teardown.
For a non-finishing recreation, preDestroy() skips networkUsageWatcher.close() because isDestroying is false. stopWatching() cancels only the sampling job; it does not close the newSingleThreadContext dispatcher. Move networkUsageWatcher.close() outside the if (isDestroying) block and add a recreation regression test.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Reject samples that cross stopWatching()
When stopWatching() acquires historyLock between the two sections in sampleOnce(), it clears lastRx and lastTx. samplingJob?.cancel() does not wait for the non-suspending sampleOnce() call to finish. The second section can therefore restore the pre-stop cumulative readings. The next sample after startWatching() can record all stopped traffic as one spike.
Use an epoch and one critical section:
🐛 Proposed fix
private var lastRx: Long? = null
private var lastTx: Long? = null
+
+ /** Bumped by [stopWatching] so a sample still in flight cannot restore the old baseline. */
+ private var baselineEpoch = 0 synchronized(historyLock) {
lastRx = null
lastTx = null
+ baselineEpoch++
} internal fun sampleOnce() {
if (!isSupported) {
return
}
+ val epoch = synchronized(historyLock) { baselineEpoch }
val rx = readRxBytes(uid)
val tx = readTxBytes(uid)
if (rx == UNSUPPORTED || tx == UNSUPPORTED) {
// Not transient: the platform either accounts for this UID or it does not.
isSupported = false
log.info("Network usage is unavailable on this device; the traffic chart will read zero")
return
}
synchronized(historyLock) {
+ // A stop landed while this sample was being read: drop it rather than record a
+ // delta against a baseline that no longer applies.

Exercise the unsupported-counter branch in NetworkWatcherLifecycleTest.
The current test calls sample(1) directly and repeats the existing isSupported == false assertion. It never runs startWatching() or verifies that the sampling loop clears watching and stops. BaseEditorActivity starts this watcher during onResume, so missing this coverage can allow unsupported devices to keep repainting the charts.
Move the case to NetworkWatcherLifecycleTest and assert isSupported == false, isWatching == false, and one sample.
