📝 WalkthroughWalkthroughThe application now uses a native Android CameraX activity for photo capture. The gallery provides camera and photo actions. Captured JPEG paths return to the Kivy flow for import and gallery navigation. Android build configuration, documentation, and supporting state handling were updated. ChangesAndroid camera capture
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR adds native camera capture and changes gallery navigation, but the current head still has concrete risks: some camera paths can crash or strand users, hidden gallery controls can intercept touches or leave the interface inconsistent, and the Android build can pass without producing an APK. These issues should be fixed or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

steps.build.outputs.apk is empty if find ./bin -name "*-debug.apk" matches nothing. actions/upload-artifact@v4 then only warns, so the workflow reports success with no artifact. Set if-no-files-found: error to surface the failure.

The manifest link is dead in the repository.
.buildozer/ is a local build output directory and is not committed. The link on line 217 also encodes one specific architecture pair, so it breaks when android.archs changes. State the path as inline text instead of a link.

Torch state desynchronizes after a camera flip.
bindCameraUseCases rebinds and produces a new Camera with the torch off. torchOn keeps its previous value. After a flip with the torch on, the flag says on while the hardware is off, so the next press turns it off logically and nothing changes visibly. Reapply the state after a successful bind.

Call super.onRequestPermissionsResult.
ComponentActivity dispatches results for registerForActivityResult permission contracts through this override. Without the super call, those callbacks never fire, which breaks any library or future contract-based request in this activity.
🛠️ Proposed fix

`@NonNull` int[] grantResults) {
+ super.onRequestPermissionsResult(requestCode, permissions, grantResults);

intent.getStringExtra returns None when the extra is absent. result[1] is then None, and copy_add([None]) passes a non-empty list into ImageOperation.__copy_add, which calls os.path.exists(None) in a worker thread and raises TypeError. Check the value before the import.
Consider also renaming callable_test to something that describes the role, for example _on_capture_result. It is a production callback, not a test helper.

The hidden action container still receives touches.
actions_container_widget starts with opacity: 0 but is not disabled. FabButtonLayout.on_touch_down blocks touches only while showing is True. adjust_children positions the container above the FAB about one second after start, so the invisible "Camera" and "Photos" buttons sit on screen and accept taps before the user opens the popup. Set disabled: True here and toggle it together with opacity in open_choice_popup and close_choice_popup.

self.app.bottom_bar is checked with the wrong guard. WallpaperCarouselApp.__init__ sets self.bottom_bar = None before build runs, so hasattr(self.app, "bottom_bar") is always True and never protects the None case. initialize_tabs on line 340 already uses the correct hasattr(...) and self.app.bottom_bar form.

Close the popup before opening the camera, and drop the duplicate navigation.
Three problems:
open_cameranever callsclose_choice_popup().showing_action_btnsstays True andfab_button.iconstays"close". After the capture returns to"thumbs", the FAB still shows the close icon and the scrim background stays applied. The next FAB press then closes an already-closed popup and appears to do nothing.- Line 689 schedules the same assignment that line 690 performs immediately, so
currentis set twice. - Line 691 relies on
current_screenalready being the camera screen. Address the screen by name to remove that assumption.
