fix(mobile): Android composer and back follow the real keyboard after resume#21595
Problem
On Android, after you leave the app with the keyboard open and come back, the chat composer stays hidden behind the keyboard. Tapping it again does not help. I hit this in daily use, and it reproduces on an emulator.
Cause: on resume, Android first reports the keyboard inset as 0 and then as its real height. react-native-keyboard-controller's native desync repair (KeyboardAnimationCallback.onApplyWindowInsets → syncKeyboardPosition) catches both, but it only emits keyboardDidHide / keyboardDidShow. On the JS side the library only marks the keyboard open on keyboardWillShow (module.ts), and useKeyboardState only listens to keyboardWillShow and keyboardDidHide. So the "hidden" repair reaches JS and the "shown" repair is dropped. useKeyboardState stays on hidden while the keyboard is on screen, and ThreadDetailScreen's KeyboardStickyView enabled={isKeyboardVisible && …} keeps the composer down.
Debug log from the emulator (unfixed main), with a temporary log of the keyboard state on ThreadDetailScreen:
| 1 | 14:54:32 KBDEBUG ctrlVisible=true ctrlHeight=336 sticky=true # composer focused |
| 2 | (Home, then back to the app) |
| 3 | 14:54:38.123 KeyboardAnimationCallback: detected desynchronized state - force updating it: 0.0 |
| 4 | 14:54:38.213 KBDEBUG ctrlVisible=false ctrlHeight=0 sticky=false |
| 5 | 14:54:38.852 KeyboardAnimationCallback: detected desynchronized state - force updating it: 336.0 |
| 6 | (no JS update follows; keyboard is on screen, composer stays under it) |
The same blind spot affected Android back. The back handlers checked React Native's cached Keyboard.isVisible(), which can stay stale after a resume, and neither Keyboard nor TextInputState can see the chat composer, which is a custom native EditText.
Change
- Extend the existing
react-native-keyboard-controller@1.22.7patch: treatkeyboardDidShowlikekeyboardWillShowinmodule.ts, and add it touseKeyboardState's events (insrc,lib/moduleandlib/commonjs). The native repair to "shown" now reaches JS. This is also a fix worth sending upstream. - New
dismissOpenKeyboard()helper. It usesKeyboardController.isVisible()andKeyboardController.dismiss(), which track the IME natively and see the composer. The thread back handler, thread search and pull request search use it: if the keyboard is really open, back closes it; otherwise back navigates or closes search. - No change to
ThreadDetailScreen. Its existing resume quarantine works once the library reports the real state.
Scope and approval
A small, focused fix for a reproducible bug, with the root cause traced through the native and JS sides of the keyboard library. Android-only behavior. No server, contract or iOS change. The library patch adds one listener and one event name.
Verification
Android emulator (Pixel 10 Pro image, Gboard), dev client against an isolated dev server. Repro: open a thread, tap the composer, press Home, return to the app, tap the composer.
Stills. Before: after resume, the composer is under the keyboard, even after tapping it again (frames 3 and 4). before stills
After: the composer stays above the keyboard after resume. after stills
- Repeated the repro 4 times after the fix, and every run ended with
ctrlVisible=true ctrlHeight=336 sticky=true. - Back after the fix: with the keyboard open, back closes it and stays in the thread, and the next back returns to the list. The same holds right after a resume. back
vp run typecheckinapps/mobilepasses. Lint shows no findings on changed code.- Not verified: a physical phone or iOS. iOS is unaffected, since its keyboard events are not repaired this way, and
ThreadDetailScreenonly gates the sticky view on Android. No tests added; the change is an event subscription in a patched dependency.
The original "back is stuck" freeze from daily use (blank feed, dead back) is not fully reproduced and may have another cause. This PR fixes the keyboard-state part that is proven.

Approvability
Verdict: Approved at f6ac662
Macroscope's review found this PR approvable — This is a small, self-contained Android keyboard-state bug fix affecting back handling and composer layout quarantine. Real keyboard dismissal remains intact, while stale cached state can no longer block navigation or leave the composer offset after resume.

📝 Walkthrough
Mobile Android back handlers use a shared helper to dismiss an open keyboard before closing search or returning to the workspace list. The keyboard-controller patch updates keyboard state events and chat scroll inset handling.

react-native-keyboard-controller 1.22.7 source module.ts isVisible isClosed dismiss keyboardDidHide keyboardDidShow
💡 Result:
| 1 | For `react-native-keyboard-controller` **1.22.7**, the source-level flow is: |
| 2 | |
| 3 | - `keyboardDidShow` sets the internal `isClosed` flag to `false`; `keyboardDidHide` sets it to `true`. |
| 4 | - `KeyboardController.isVisible()` returns `!isClosed`. |
| 5 | - `KeyboardController.dismiss()` resolves immediately if `isClosed` is already true. Otherwise it waits for a one-time `keyboardDidHide` event, calls the native dismiss method, and resolves when that event arrives. ([deepwiki.com](https://deepwiki.com/kirillzyusko/react-native-keyboard-controller/4.1-keyboardcontroller-module?utm_source=openai)) |
| 6 | |
| 7 | I couldn’t verify the **1.22.7** `module.ts` directly: the source result I found describes `src/module.ts` but does not establish that it is specifically version 1.22.7. The closest versioned type source found was 1.21.9, so confirm against the installed 1.22.7 package before relying on exact implementation details.

Add a recovery path for stale keyboard visibility.
KeyboardController.isVisible() uses a cached isClosed flag. KeyboardController.dismiss() waits for keyboardDidHide when that flag is open, but does not clear it itself. Android emits the repair event only when onApplyWindowInsets detects a height change and the callback is not moving or suspended.
If that repair is skipped after a dropped hide event, dismissOpenKeyboard() returns true on every back press. The affected handlers then skip navigation or search closure. Add a fallback for this stale state. Do not restore the old React Native focus check because it does not detect the custom composer.

- fix(mobile): Android back recovers when a keyboard hide event is missed524faa2
Synced from GitHub
Filed #22484 to track the remaining keyboardDidShow cache/hook defect and linked this PR as the existing fix. I independently observed the same native recovery sequence while investigating Android split-screen in Harbordex, then reproduced the JS state and dismissal failures against upstream 7e289ae1.
Regression coverage is available as a test-only commit, including the mobile React-test allowlist entry. It can be cherry-picked independently of the verification patch commit, which adds the same event subscriptions proposed here.
The tests exercise the real package source cache and mounted hook with only native bindings mocked. From apps/mobile:
sh
| 1 | vp test run --project react src/features/keyboard/keyboardControllerState.test.tsx |
All three fail on the baseline and pass with the listeners added:
didShowwithoutwillShowupdates both cache and mounted hook to visible with the reported height.dismiss()remains pending untildidHide, instead of resolving immediately against a stale hidden cache.- Normal
willShowis still immediate, anddidShowsupplies the completed height before a later hide resets the state.
Targeted formatting/lint, mobile typecheck, and native lint pass. The existing 18 dependency-patch sections remain byte-for-byte unchanged.
The older fork's split-screen composer failure was verified on an Android 17 tablet emulator. At the time of the initial comment, no current-upstream native UI run had been completed: #20803 and #19980 changed the composer gates since that fork's base. The new tests establish the remaining state/dismissal contract failure. This was initially shared as supplementary evidence and coverage for your existing fix.
Update: a separate, narrowly scoped PR was subsequently requested and opened as #22514, linked to #22484. It contains the state repair and regression tests, explicitly acknowledges the overlap here, and excludes Android Back handling. Native Android split-screen verification against the upstream base now also reproduces the stale cache/hook before the patch and correct state afterward; the composer remains visible in both upstream variants. Details, before/after screenshots, and short native recordings are in #22514 and #22484.
