Building the camera app for volla phone

ubports-user

Hello there,

because the camera on volla phone stopped to work after installing updates (it just crashes after i displays the splash), I decided to install older versions, because I thought it might be caused by the patches made to the camera app.

So I have build the following versions via clickable:

camera-app-v3.0.1.765
camera-app-v3.1.2

Both versions still crash.

I wonder about the following messages produces by clickable --debug:

Framework in manifest is "ubuntu-sdk-15.04.4", Clickable expected "ubuntu-sdk-16.04.5".

How do I switch the framwork which clickable uses? I would like to compile with the framework specified in the manifest. The clickable documentation does not tell me how to switch to older framework.

Then there is another message:

- functional:qt_qml_import_versions_framework
	Files contain QML imports too new for frameowrk used: SlideshowView.qml,FocusRing.qml,ViewFinderOverlay.qml,ShootButton.qml,ViewFinderView.qml,ProcessingFeedback.qml,Information.qml,PhotoEditorLoader.qml,ViewFinderExportConfirmation.qml,ViewFinderOverlayLoader.qml,VideoReview.qml,GalleryViewLoader.qml,OptionsOverlay.qml,OverlayBlur.qml,AdvancedOptions.qml,PictureReview.qml,StopWatch.qml,GalleryView.qml,PhotoRollHint.qml,OptionValueButton.qml,ResponsiveGridView.qml,BottomEdgeIndicators.qml,PhotogridView.qml,OptionButton.qml,NoSpaceHint.qml,camera-app.qml,GalleryViewHeader.qml,ViewFinderGeometry.qml,UnableShareDialog.qml,SharePopover.qml,DeleteDialog.qml,IconButton.qml,CircleButton.qml,ThinSliderStyle.qml,ZoomControl.qml

OK, I do not understand the problem here, just wanted to mention this.

Then another log message regarding app.armor:

 - security:policy_groups_safe:camera:picture_files
	(NEEDS REVIEW) reserved policy group 'picture_files': vetted applications only
 - security:policy_groups_safe:camera:video_files
	(NEEDS REVIEW) reserved policy group 'video_files': vetted applications only
 - security:redflag_fields:camera.apparmor
	found redflagged fields (needs human review): read_path

I'm not sure if that problem maybe is enough to stop app.armor to not run the at all via clickable --debug?

Sorry for beeing not so verbose on this topic, I'm very new to the system and environment - searching for some inputs, hints, etc. how to get some grab on the topic.

The last version is 3.2.3 maybe it solve your problem.
I've got volla phone as well and camera app works very well.

The camera app has been working for me on Volla with no problems - on both OTA17 Stable and RC channels. I would suggest resetting or reinstalling to try and fix this

Thank you very much for your quick replies.

Hard-Reset is an viable option then. However, my questions remain valid and maybe I can pinpoint the problem. In /var/log I can not see any crash dumps, is there some other location for logs like kern.log or is there some tool like ltrace?

After all, I think the system should at least create some log entry when an application is shut down for whatever reason.

@ubports-user - you can install the Logviewer app from the Open Store to view more log info.

OK, but I do not see anything related to the camera there.

However, I had a look into the system settings app and within the section "Application Authorisation" I see an section for camera, but 0 apps are configured to have camera access in that section. When I look into UT Tweak Tool, the camera app is described to have access to the camera.
I start to believe app.armor is maybe the right place to start searching for the problem, will dig into that
