NC Collectives

An unofficial native Android client for the Nextcloud Collectives app — wiki-style markdown notebooks hosted on your own Nextcloud server.

Features:

* Browse collectives and nested page trees.

* Render markdown pages, including images, links, task lists, tables, syntax-highlighted fenced code blocks (Prism4j, themed against the app's Material 3 colour scheme), Nextcloud Text callouts (INFO / WARN / ERROR / SUCCESS), and ==highlight== marks.

* View-first by default with a per-page edit toggle. Two editors ship side-by-side: a native markdown editor with formatting toolbar + live preview swap that works offline (default), and a collaborative WebView editor backed by Nextcloud Text (beta — multi-user real-time editing, callouts, multi-line tables, math) used when the server supports it and you're online. Choose the default under Settings → Editor.

* Offline read cache and offline edit queue. Last-write-wins on conflict; local edits are preserved as drafts attached to the page.

* Full-text search via the Nextcloud unified-search provider.

* Favourites and recent searches, persisted across sessions.

* Per-page tags, emoji, rename, and move (folder pages supported). Browse all pages carrying a given tag.

* Long-press to drag pages and reorder them within their parent — same subpageOrder the web Collectives UI uses.

* Duplicate page action.

* Attachments: view inline images, upload from camera or gallery.

* Trash + restore (per-page and per-collective), with pre-commit undo on a snackbar for page trash.

* Create new collectives, change a collective's emoji, soft-delete + restore + permanently delete collectives.

* Share-intent quick capture from any app (text, URLs, single or multiple images).

* Backlinks: collapsible "linked from" row under every page that shows which other pages reference it.

* Wikilink support: [[Page Name]] and relative .md links resolve in-app.

* Light, Dark, or System theme; Material 3 styling.

* Configurable background sync cadence (Off, 1h, 6h, 12h, daily).

* Adaptive launcher icon with a monochrome layer for Android 13+ themed icons.
