Galaxy S8 with Android 7 - Photo crash

[gnerred]

Some users reported me problems for making QField work on Galaxy S8 and Android 7. At this time I don't have all details, but :

• Geolocation not working
• Problem saving data
• Crash when doing a picture

Are problems known with this configuration ?

[m-kuhn]

Apparently there is a problem with loading the CRS database.
We are not sure if it's related to this device or to Android 7 in general or something else.

[gnerred]

Ok thanks, let met know if we can help in solving this issue.

[m-kuhn]

A device and ~2 days (very rough estimation, might be better or worse) to investigate will help

[gnerred]

Ok thanks I will come back to you if I can find what you need.

Background information
QField version 0.8.8
Device: Samsung Galaxy S6 Edge, Andoid 7
QField project is made with QGIS 2.18.9 where the fieldtype for the photo-field is defined as External resources:

The case

• Geolocation working :)
• Saving data works fine :)
• BUT Crash when saving a picture

I have the same problem with crash when saving a picture from QField. This means that I do get a possibility to open the camera and take a picture, but when I press 'OK', QField crashes (as illustrated below:

[donkey12345]

I think the picture is best stored in a file format.and Save the path to the database.

[m-kuhn]

I think the picture is best stored in a file format.and Save the path to the database.

That's correct.

I recently found a device that shows a strange behavior with pictures (QField restarted) but unfortunately no hint in the logs what went wrong. Looks like the fix needs some more time invested.

[hpethen]

I have also experienced this problem, exactly the same as MieWinstrup, but with my Galaxy tab S2, also running Android 7.

[treenerd]

Hi Same issue here with:
Nexus 5X and Android 7.1.2;
QGIS 2.18.9 on Fedora 25
export done with QFieldsync 1.0.0
QField version 0.10.0

[jbostoen]

As regular users, what could we do to help solve the camera crash issue?

Tried it on 3 smartphones; it crashes.

• Huawei Ascend Y II, Android 5.1 Lollipop
• OnePlus 3, Android 7.1.1 Nougat
• Moto G4, Android 7.0 Nougat

On a Samsung tablet, it works fine.

Hope it helps

[m-kuhn]

for adventurous people.
we'll be happy to receive feedback on this apk, if it resolves the issue.
please only comment on if it crashes, we are fully aware, that it's not beautiful currently ;)

[jbostoen]

It's different. On my smartphone, the picture is in the wrong orientation. Also, I don't see a 'take photo' button or whatever you want to call it. Just a picture.

[gnerred]

I tried this version on a Galaxy S6 with Android 7 and when I take a picture :

• the image is not oriented properly
• there is no button to take the picture...

[m-kuhn]

Sorry, forgot some context.
The device needs to be in portrait position and the buttons are well hidden (as said before, it's not yet nice to use).
We're also aware of the wrong picture orientation, that will be fixed in a final version.

[jbostoen]

• buttons were completely invisible for me
• taking picture - doesn't crash :D
• trying to press where you have the X, this doesn't seem to do much except for remving the photo and allowing you to take another one ?

[m-kuhn]

taking picture - doesn't crash :D

🎉

[mrciftci]

Qfield closes because it can not create the folder (DCIM) when the picture is taken. How the problem can be solved.

[m-kuhn]

because it can not create the folder (DCIM) when the picture is taken

do you have an error message that indicates this? which path is your project stored in?

[mp-dmsi]

Tested this version on an ASUS P01T (Android 6.0.1) that previously crashed when taking picture and guess what?...no crash

[signedav]

#238 <- should be solved here.

@mrciftci Do you have this problem still with the latest version? I cannot reproduce it on my device. Thanks for your help!

[VxTedxV]

Experienced same initial issue with the following config :
Samsung Galaxy XCover4 Android 7.0
QField 0.10.12
"use native camera function" checked
(when unchecked, works fine but bothered by the lack of parameters to take photos like no zooming for example -> do I have to open a request about that ?)

No bug with the same project on Samsung Galaxy XCover3 Android 6.0 QField 0.10.9

[signedav]

Hi @VxTedxV Thanks. The native camera is the one that crashed and still crashes on some device. We disabled it per default.

There's not yet an open request for the zooming feature in the QField-Camera. But I agree that it would be good to have that. What are other things that could be needed in your opinion?

[VxTedxV]

With native camera I had access to different native tools :

• image format (4:3, 16:9, 1:1...) with different width/height (more or less weight)
• timer (countdown before taking picture)
• geolocalisation EXIF tag on/off
• zoom with fingers
• flash on/off/auto
• mode "pro" to adjust ISO/luminosity/WB/spot or matrice mesure and more...
• panorama mode
• ...
  That's a lot of features that can be useful outside ! But I understand that would be too much to develop. We both know the best answer would be to find what could make work native camera with any config !

[m-kuhn]

Yes, that's why we originally implemented the native camera. I am confident that we can also get the native camera working again. We recently did some tests with promising results. We would need around 4 days to work on that, if it's important enough for someone to sponsor this, we will be more than happy to reintroduce it.
