The splash background was #09090b in both modes, so in light mode a
cold start went from a near-black splash to the white first frame.
It is now #ffffff by day and #09090b at night (`values-night`), as
`splash.backgroundColor` and `splash.dark.backgroundColor` in
app.config.js already ask for, so a later `expo prebuild` writes the
same colours. Checked on the API 35 emulator: light mode stays white
from splash to login screen, dark mode is unchanged.
Every background push kept the app awake for the full 30 s timeout of
the BulwarkPushTask headless task, however quickly the task was done.
AppRegistry reports a finished task through the native
HeadlessJsTaskSupport module, and React Native 0.81 registers that
module only for the old bridge (CoreModulesPackage); the bridgeless
runtime's CoreReactPackage leaves it out. JS could never say it was
done, so the service, or the job, and its wake lock waited for the
timeout. BulwarkHeadlessJsTaskSupportModule provides the module under
the same name when the app runs bridgeless.
The push path also leaked a wake lock now and then. startHeadlessTask
called HeadlessJsTaskService.acquireWakeLockNow on the FCM worker
thread while the service took the same static lock on the main thread.
The method is not thread-safe, so both could create a lock, and the one
that was overwritten stayed held. The FCM thread now takes its own
wake lock, timed at 10 s, and the service drops it as soon as it holds
React Native's.
Measured on the API 35 emulator with the R8 release build:
- push handled by the job: 30,000 ms before, 75-155 ms now
- push handled by the service: the service ran 31 s before, it is
gone within a second now
- `com.facebook.react.i` wake lock still held 5 s after a push: 2 of
4 pushes before, 0 of 8 now
A push that arrived while the app was in the background started
BulwarkPushTaskService with `startService`. Android 8+ allows that only
while the app is temporarily allowlisted, which a high-priority FCM
message grants. The relay does send FCM data messages at HIGH priority,
but FCM delivers some at normal priority anyway (it downgrades apps
whose high-priority messages rarely end in a notification), and a
UnifiedPush distributor may not raise the app at all. The call then
threw `BackgroundServiceStartNotAllowedException` and the app crashed,
from the FCM thread or, for UnifiedPush, on the main thread.
The service start is kept as the first choice, so a high-priority push
works as before. When Android refuses it, the same headless task now
runs from a JobScheduler job (BulwarkPushJobService): expedited on
Android 12+, which runs at once while the app has expedited-job quota
and as a regular job after that, and a regular job on Android 8-11.
JobScheduler is a platform API, so nothing is added to the build;
WorkManager is not in the dependency tree. A generic "new mail"
notification built natively was the other option, but the relay's
payload cannot tell new mail from other changes and the native side
knows neither the notification settings nor what was already shown.
Checked on the API 35 emulator with the R8 release build, the process
killed and the push delivered past the allowlist:
- FCM data message: before, FATAL EXCEPTION on
Firebase-Messaging-Intent-Handle; now the job is scheduled 18 ms
after the refusal and runs the task
- UnifiedPush message (connector 3.3.5, sent the way a distributor
does): before, FATAL EXCEPTION on main; now the same job path
- allowlisted FCM message: still starts BulwarkPushTaskService
On a cold start the splash was followed by about a second of blank
white, then mail rows whose header sat under the status bar until it
popped in and pushed the list down.
- `AppTheme` had no `android:windowBackground`, so while JS loaded the
window showed the platform default (near-white, or grey at night).
It is now the app's own background, #ffffff by day and #09090b at
night (`values-night`), matching `src/theme/tokens.ts`.
- `NavigationContainer` had no theme, so React Navigation painted its
light default behind and between screens even in dark mode. It now
uses the palette's background.
- The mail list took its top inset from the native `SafeAreaView`,
which on Fabric only learns the insets a few frames after mounting.
It now pads with `useSafeAreaInsets()`, which the navigator's
safe-area provider fills from the initial window metrics on the first
render; the value is the same, it just arrives in time.
The notification only carried the local account it was posted for, so
tapping one for a message in a group or shared mailbox opened the
thread against the user's own JMAP account, where the message doesn't
exist.
The background task now passes the JMAP account the message was
fetched from as `jmapAccountId`. The native module stores it as an
intent extra, validated like the other ids, and hands it back with the
tap. `App.tsx` routes the open with it, the way the unified inbox does
for group messages. Notifications posted before this change have no
such extra and open against the account's own mail as before.
Most apps start an email with `ACTION_SENDTO` and a `mailto:` URI. The
manifest offered the app for it, but React Native's Linking only
forwards VIEW intents, so the app opened on the inbox instead of the
composer.
MainActivity now rewrites a `SENDTO mailto:` intent into the equivalent
`VIEW mailto:` link before React Native sees it, on a cold start and
when the running app receives it. The EXTRA_EMAIL, EXTRA_CC, EXTRA_BCC,
EXTRA_SUBJECT and EXTRA_TEXT extras are folded into the link's query.
Bcc recipients of a mailto link now reach the composer too; they were
dropped for VIEW links as well.
Sharing a photo or document from another app into Bulwark failed every
time: the upload task was handed the share's `content://` URI, but it
can only stream from a file path, so it failed with "Directory for
'/external/images/media/…' doesn't exist". The attachment was also named
after the URI's last segment (a MediaStore row id such as "1000000027"),
and SEND_MULTIPLE shares only carried a wildcard type like `image/*`.
- `uploadBlob` copies `content://` URIs into the cache, uploads the copy
and deletes it afterwards, also when the upload fails
- `ShareIntentStore` asks the providing app for the display name, size
and MIME type when the intent arrives, falling back to the URI segment
plus an extension for the MIME type
- the composer gets the real name, type and size, so the size limit
check now applies to shared files too
CI:
- .github/workflows/release-android.yml builds APK on release publish
and via workflow_dispatch, attaches it to the release.
- android/app/build.gradle: optional release signingConfig driven by
Gradle properties (ANDROID_KEYSTORE_BASE64 secret etc.); falls back
to the debug keystore when no secrets are set.
- .gitignore: untrack /android so the runner can build directly;
ignore build outputs (build/, .cxx/), Metro/Expo dev logs, scratch.
Track android/ sources including BulwarkFcmPackage.kt and
google-services.json (Firebase Android keys are public per Google's
docs and intended to ship in the APK).
JS sync: push notifications + background task, vacation responder
(api + store), contact activity component, search utilities, settings
polish, calendar/contacts/email store and screen tweaks.
Tooling: scripts/poll-reload.mjs — Windows polling-watcher that hits
Metro /reload on file change (workaround for unreliable fs.watch
without Watchman).
