refactor: implement ActivityManager (#1016) ## Summary Ref comment: https://github.com/crosspoint-reader/crosspoint-reader/pull/1010#pullrequestreview-3828854640 This PR introduces `ActivityManager`, which mirrors the same concept of Activity in Android, where an activity represents a single screen of the UI. The manager is responsible for launching activities, and ensuring that only one activity is active at a time. Main differences from Android's ActivityManager: - No concept of Bundle or Intent extras - No onPause/onResume, since we don't have a concept of background activities - onActivityResult is implemented via a callback instead of a separate method, for simplicity ## Key changes - Single `renderTask` shared across all activities - No more sub-activity, we manage them using a stack; Results can be passed via `startActivityForResult` and `setResult` - Activity can call `finish()` to destroy themself, but the actual deletion will be handled by `ActivityManager` to avoid `delete this` pattern As a bonus: the manager will automatically call `requestUpdate()` when returning from another activity ## Example usage **BEFORE**: ```cpp // caller enterNewActivity(new WifiSelectionActivity(renderer, mappedInput, [this](const bool connected) { onWifiSelectionComplete(connected); })); // subactivity onComplete(true); // will eventually call exitActivity(), which deletes the caller instance (dangerous behavior) ``` **AFTER**: (mirrors the `startActivityForResult` and `setResult` from android) ```cpp // caller startActivityForResult(new NetworkModeSelectionActivity(renderer, mappedInput), [this](const ActivityResult& result) { onNetworkModeSelected(result.selectedNetworkMode); }); // subactivity ActivityResult result; result.isCancelled = false; result.selectedNetworkMode = mode; setResult(result); finish(); // signals to ActivityManager to go back to last activity AFTER this function returns ``` TODO: - [x] Reconsider if the `Intent` is really necessary or it should be removed (note: it's inspired by [Intent](https://developer.android.com/guide/components/intents-common) from Android API) ==> I decided to keep this pattern fr clarity - [x] Verify if behavior is still correct (i.e. back from sub-activity) - [x] Refactor the `ActivityWithSubactivity` to just simple `Activity` --> We are using a stack for keeping track of sub-activity now - [x] Use single task for rendering --> avoid allocating 8KB stack per activity - [x] Implement the idea of [Activity result](https://developer.android.com/training/basics/intents/result) --> Allow sub-activity like Wifi to report back the status (connected, failed, etc) --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers.

refactor: move render() to Activity super class, use freeRTOS notification (#774) ## Summary Currently, each activity has to manage their own `displayTaskLoop` which adds redundant boilerplate code. The loop is a wait loop which is also not the best practice, as the `updateRequested` boolean is not protected by a mutex. In this PR: - Move `displayTaskLoop` to the super `Activity` class - Replace `updateRequested` with freeRTOS's [direct to task notification](https://www.freertos.org/Documentation/02-Kernel/02-Kernel-features/03-Direct-to-task-notifications/01-Task-notifications) - For `ActivityWithSubactivity`, whenever a sub-activity is present, the parent's `render()` automatically goes inactive With this change, activities now only need to expose `render()` function, and anywhere in the code base can call `requestUpdate()` to request a new rendering pass. ## Additional Context In theory, this change may also make the battery life a bit better, since one wait loop is removed. Although the equipment in my home lab wasn't been able to verify it (the electric current is too noisy and small). Would appreciate if anyone has any insights on this subject. Update: I managed to hack [a small piece of code](https://github.com/ngxson/crosspoint-reader/tree/xsn/measure_cpu_usage) that allow tracking CPU idle time. The CPU load does decrease a bit (1.47% down to 1.39%), which make sense, because the display task is now sleeping most of the time unless notified. This should translate to a slightly increase in battery life in the long run. ``` PR: [40012] [MEM] Free: 185856 bytes, Total: 231004 bytes, Min Free: 123316 bytes [40012] [IDLE] Idle time: 98.61% (CPU load: 1.39%) [50017] [MEM] Free: 185856 bytes, Total: 231004 bytes, Min Free: 123316 bytes [50017] [IDLE] Idle time: 98.61% (CPU load: 1.39%) [60022] [MEM] Free: 185856 bytes, Total: 231004 bytes, Min Free: 123316 bytes [60022] [IDLE] Idle time: 98.61% (CPU load: 1.39%) master: [20012] [MEM] Free: 195016 bytes, Total: 231532 bytes, Min Free: 132460 bytes [20012] [IDLE] Idle time: 98.53% (CPU load: 1.47%) [30017] [MEM] Free: 195016 bytes, Total: 231532 bytes, Min Free: 132460 bytes [30017] [IDLE] Idle time: 98.53% (CPU load: 1.47%) [40022] [MEM] Free: 195016 bytes, Total: 231532 bytes, Min Free: 132460 bytes [40022] [IDLE] Idle time: 98.53% (CPU load: 1.47%) ``` --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers.

Rotation Support (#77) • What is the goal of this PR? Implement a horizontal EPUB reading mode so books can be read in landscape orientation (both 90° and 270°), while keeping the rest of the UI in portrait. • What changes are included? ◦ Rendering / Display ▪ Added an orientation model to GfxRenderer (Portrait, LandscapeNormal, LandscapeFlipped) and made: ▪ drawPixel, drawImage, displayWindow map logical coordinates differently depending on orientation. ▪ getScreenWidth() / getScreenHeight() return orientation‑aware logical dimensions (480×800 in portrait, 800×480 in landscape). ◦ Settings / Configuration ▪ Extended CrossPointSettings with: ▪ landscapeReading (toggle for portrait vs. landscape EPUB reading). ▪ landscapeFlipped (toggle to flip landscape 180° so both horizontal holding directions are supported). ▪ Updated settings serialization/deserialization to persist these fields while remaining backward‑compatible with existing settings files. ▪ Updated SettingsActivity to expose two new toggles: ▪ “Landscape Reading” ▪ “Flip Landscape (swap top/bottom)” ◦ EPUB Reader ▪ In EpubReaderActivity: ▪ On onEnter, set GfxRenderer orientation based on the new settings (Portrait, LandscapeNormal, or LandscapeFlipped). ▪ On onExit, reset orientation back to Portrait so Home, WiFi, Settings, etc. continue to render as before. ▪ Adjusted renderStatusBar to position the status bar and battery indicator relative to GfxRenderer::getScreenHeight() instead of hard‑coded Y coordinates, so it stays correctly at the bottom in both portrait and landscape. ◦ EPUB Caching / Layout ▪ Extended Section cache metadata (section.bin) to include the logical screenWidth and screenHeight used when pages were generated; bumped SECTION_FILE_VERSION. ▪ Updated loadCacheMetadata to compare: ▪ font/margins/line compression/extraParagraphSpacing and screen dimensions; mismatches now invalidate and clear the cache. ▪ Updated persistPageDataToSD and all call sites in EpubReaderActivity to pass the current GfxRenderer::getScreenWidth() / getScreenHeight() so portrait and landscape caches are kept separate and correctly sized. Additional Context • Cache behavior / migration ◦ Existing section.bin files (old SECTION_FILE_VERSION) will be detected as incompatible and their caches cleared and rebuilt once per chapter when first opened after this change. ◦ Within a given orientation, caches will be reused as before. Switching orientation (portrait ↔ landscape) will cause a one‑time re‑index of each chapter in the new orientation. • Scope and risks ◦ Orientation changes are scoped to the EPUB reader; the Home screen, Settings, WiFi selection, sleep screens, and web server UI continue to assume portrait orientation. ◦ The renderer’s orientation is a static/global setting; if future code uses GfxRenderer outside the reader while a reader instance is active, it should be aware that orientation is no longer implicitly fixed. ◦ All drawing primitives now go through orientation‑aware coordinate transforms; any code that previously relied on edge‑case behavior or out‑of‑bounds writes might surface as logged “Outside range” warnings instead. • Testing suggestions / areas to focus on ◦ Verify in hardware: ▪ Portrait mode still renders correctly (boot, home, settings, WiFi, reader). ▪ Landscape reading in both directions: ▪ Landscape Reading = ON, Flip Landscape = OFF. ▪ Landscape Reading = ON, Flip Landscape = ON. ▪ Status bar (page X/Y, % progress, battery icon) is fully visible and aligned at the bottom in all three combinations. ◦ Open the same book: ▪ In portrait first, then switch to landscape and reopen it. ▪ Confirm that: ▪ Old portrait caches are rebuilt once for landscape (you should see the “Indexing…” page). ▪ Progress save/restore still works (resume opens to the correct page in the current orientation). ◦ Ensure grayscale rendering (the secondary pass in EpubReaderActivity::renderContents) still looks correct in both orientations. --------- Co-authored-by: Dave Allie <dave@daveallie.com>

feat: Move Sync feature to menu (#680) ## Summary * **What is the goal of this PR?** Move the "Sync Progress" option from TOC (Chapter Selection) screen to the Reader Menu, and fix use-after-free crashes related to callback handling in activity lifecycle. * **What changes are included?** - Added "Sync Progress" as a menu item in `EpubReaderMenuActivity` (now 4 items: Go to Chapter, Sync Progress, Go Home, Delete Book Cache) - Removed sync-related logic from `EpubReaderChapterSelectionActivity` - TOC now only displays chapters - Implemented `pendingGoHome` and `pendingSubactivityExit` flags in `EpubReaderActivity` to safely handle activity destruction - Fixed GO_HOME, DELETE_CACHE, and SYNC menu actions to use deferred callbacks avoiding use-after-free ## Additional Context * Root cause of crashes: callbacks like `onGoHome()` or `onCancel()` invoked from activity handlers could destroy the current activity while code was still executing, causing use-after-free and race conditions with FreeRTOS display task. * Solution: Deferred execution pattern - set flags and process them in `loop()` after all nested activity loops have safely returned. * Files changed: `EpubReaderMenuActivity.h`, `EpubReaderActivity.h/.cpp`, `EpubReaderChapterSelectionActivity.h/.cpp` --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers.
