ZenNotes for Android 1.1.19 (versionCode 21): lighter sync, better touch

Cloud sync stops redoing work it has already done, the editor handles touch more carefully, images paste straight from the keyboard, and the launch splash is the same on every Android version. Eight tracker reports (#48 to #55). The pin stays at main's 431907df (app core 2.47.0), so this is also the first Play release carrying 2.47 and the comment-sidecar fix from #61.

What ships

• Cloud sync responsiveness (64fea20, Editor Becomes Sluggish While Cloud Sync Is in Progress #52): acknowledged unchanged files are fingerprinted instead of reread, no-op syncs skip the view refresh, incoming changes refresh once as a batch, large attachments decode in chunks with UI yields, binary uploads reuse their base64. Conflict review still reads the real file. cloud-sync-repository.ts, cloud-sync-work.ts, cloud-sync-refresh.ts, plus an integration test through the real mobile adapter.
• Keyboard image paste (e424325, Pasting Images into the Editor Is Not Supported #54): Android Commit Content API on a Capacitor WebView subclass; temporary content:// grants, bounded cancellable reads, PNG/JPEG/GIF/WebP signature checks, 10 MiB cap, note/vault/editor context re-checked before insertion. WebP keeps its filename in the self-hosted RemoteVault path.
• Editor touch and overlays (1846f0c): Cloud footer gets a 44 px row and the floating controls sit above it (Floating Action Button Overlaps the Cloud Connect Button #48); wikilinks navigate only on a completed tap (Wikilinks Are Incorrectly Activated While Scrolling or Extending Text Selections #50); the docked selection toolbar reserves real layout space (Format Selection Menu Still Overlaps Text When the Keyboard Is Open #51); every sheet's pill is a draggable 44 px handle (Menu Drag Pill Does Not Allow the Menu to Be Dragged #53); opaque body/root/editor surfaces as an unverified flicker mitigation (Editor Background Colour Flickers While Extending Text Selection #49).
• Launch splash (7c945b1, Splash Screen Icon Has Inconsistent Shape Across Android Versions  #55): AndroidX compat splash installed before Capacitor switches theme, square icon canvas, duplicate plugin splash disabled.
• Validation doc and browser fixture (bd6c09a); version bump 1.1.19 / versionCode 21 and the release pack docs/releases/v1.1.19/ (last commit).

Verification (2026-09-11)

• Release build at the pin: npm run typecheck clean, npm test 121/121, Gradle testDebugUnitTest 9/9, bundleRelease signed with the upload key; merged manifest versionCode 21 / 1.1.19; AAB sha256 cc93676c880a9e2b0e6f825b06a9e16299ed14b7d26283fdbed2b5a300423bfe.
• Pixel 7 API 35 emulator: the debug build of the same tree installs as versionCode 21 and launches to the workspace, opens the ⊕ menu and the More sheet, and dismisses the sheet on a downward handle drag (Menu Drag Pill Does Not Allow the Menu to Be Dragged #53), with no crash in logcat.
• Browser fixture checks (Cloud footer height, toolbar/scroller split, handle activation, opaque surfaces) recorded in docs/android-issue-validation-2026-09-11.md.
• Not verified on hardware: typing during a live Cloud sync, Gboard image paste, and the Editor Background Colour Flickers While Extending Text Selection #49 flicker.

The sync work pairs with ZenNotes for iOS 1.9.9 (release/1.9.9).
