Hi,
Here is my first app "Taquin" a simple and classic puzzle game, that I have just published on the OpenStore and the source here: https://gitlab.com/AloysLiska/taquin

Please be indulgent, that's a beginner work, but I would appreciate your feedback on the app, on the code,etc.

QML and javascript were new for me (I have software skill and I mainly developed in C).
To begin with QML, I use : https://doc.qt.io/qt-5/qml-tutorial1.html, and https://mimecar.gitbook.io/qt-course/
And for javascript I use : https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide.
And of course I use the UBPorts documentation.

My editor was Kate (default editor of Kubuntu), simple and sufficient I think for a simple app.
When you begin, there is a lot to learn, so I did not want to use something new for me (like Qtcreator or another editor).

For the next version of Taquin, my objective is to allow user to select an image in its gallery.

Enjoy the app (kind of game useful to kill time)!

@Lakotaubp, I fully charged the battery as you said, but it was the same problem, it was stuck in the first screen.

I tried to start the phone on bootloader by holding pwr and vol down buttons, but I never succeed!

I tried UBports installer, but last version 0.1.21 does not work with my FP2, I have the issue:
Fastboot: Unknown error: downloading 'boot.img'...OKAY [ 0.360s]booting...FAILED (remote: bootimage: incomplete or not signed)finished. total time: 0.361s

I add this problem before, see:
How to manually upgrade from OTA-3 to OTA-4 and @advocatux suggested to use the UBports installer V0.1.12.

I launched this version and it finally works!
I had to select manually the device to FP2, because device was not automatically detected. I reboot with pwr+voldown or pwr+volup+voldown buttons several times, after several reboots, it succeed to detect the device, and the update procedure went till the end successfully.

Now I have the OTA 8 and all my data.

Thank you @AlainW94 and @Lakotaubp

Thanks @cibersheep for your answers, I succeed to do what I want with Content Hub and a C++ plugin to manage file deletion and renaming.
I wrote a a sample app available here: importwithcontenthub, with many (too much!) comments.
This sample app allow user to import an image, the image is stored (so that it is available on next app launch). And when user imports a new image, it is stored by overwriting the last one (only last imported image is stored).

Thank you @advocatux.
I have the version: com.ubuntu.camera 3.0.1.765

Hello,
I have exactly the same issue on my Fairphone2. I just had it, install UT successfully (15.04 rc). I install telegram application from the open store, but I cannot search a group, there is no button for that. When I go to contact or to new group, it is in endless loading loop. In the scope, when I try to search, I have no keyboard and I cannot paste in the search field.
I do not know what t do.

Hi,

Just to say that now with UT 16.04, no more problem, I can connect by ssh from my phone (ssh client) to my PC (ssh server) by using the public/private key authentication.

Yes! it is working with last clickable version (6.23.3).
Thank you @lduboeuf !

Thank you @cibersheep , your code helps me to do mine!

Thanks @marathon2422 and @Opolork ,
I am pleased that you like it, I also received contributions for translations, that's motivating for me, I will update the app!

I found my problem: my docker image was obsolete.
I delete the docker image "clickable/ubuntu-sdk 16.04-amd64"
I launch again: clickable desktop
It download a new image and run successfully without error.

I did not know anything about docker, here is what I discover:

• First I read a bit on docker: https://docs.docker.com/get-started/
  I understand that with docker there is the image and the container. The container is the execution of the image. The image can be downloaded from docker hub and I think this is what clickable does, the image for 16.04-amd64 is here https://hub.docker.com/r/clickable/ci-16.04-amd64 . And I suppose this image is built from: https://gitlab.com/clickable/clickable-docker-images/-/tree/master/ubuntu-sdk/16.04-amd64
• to list the images: docker image ls

REPOSITORY             TAG                 IMAGE ID            CREATED             SIZE
clickable/ubuntu-sdk   16.04-armhf         62adb04a1781        13 months ago       2.92GB
clickable/ubuntu-sdk   16.04-amd64         b2a675929781        13 months ago       2.77GB

as you see my images were 13 months old!

• to delete the 16.04-amd64 image: docker rmi b2a675929781
• and I delete also the 16.04-armhf image

There is probably a better solution to update a docker image, no?

@mardy I did not success to make it work, I have error:

qrc:/Main.qml:85: TypeError: Property 'sync' of object QQmlSettings_QML_16(0x13ee5d0) is not a function

I may miss something! I have id of Settings named appSettings, then I call appSettings.sync().

@cibersheep I will probably do as you said in a next release (I release recently with saving only on application inactive).
I did not do it it initially because it seems for me more proper to not cause file writing on each tile move done by the user. When playing, we can easily have hundreds of move, so hundred time of file writing (in fact i do not know how the os manage this, with cache or direct flash writing?...).

Considering the problems I have encountered, this would be much simpler ... if i do not find another unexpected behavior!!! I was a bit discouraged with all these problems and the time spent on them, but let see the positive point, I have learned a lot.

Thank you all for your help!

In fact, not so simple! I just discover another unexpected behavior.
I use Settings to save status of the game, and when adding saving on signal AboutToQuit(), the file (taquin.aloysliska.conf) is not updated.

See below a simplified example from my app:

    Settings { 
        id: settings
        property int savedmovcount: 0
    }

...

Connections {
        target: Qt.application
        onAboutToQuit: {
            settings.savedmovcount = movcount     // save movcount in settings
            console.log("savedmovcount", settings.savedmovcount)   // re-read and display saved value
        }
    }

I see in the log that settings.savedmovcount has the expected value, but the file was not updated.

Thanks @kugiigi , you're right, I will do it, this will be more robust.

And that's so simple! it works by just adding:

Connections {
        target: Qt.application
        onAboutToQuit: {
            console.log("About to Quit")
        }
    }

But finding the solution is not simple!

Thank you @lduboeuf and @mardy , I use the Qt.application.active signal to fix my issue (here). What I need is to save data, so this method is appropriate for my app.

Note that when launching app on desktop (with clickable desktop), closing the app with the cross button (at upper right) will not generate this signal. But it seems not a problem at all on the device because to close the app, user need to "slide and throw" which cause a switch in an inactive state.

This should allow me to release new version of my Taquin app!

Hi,

In my Taquin app, in branch develop here, Component.onDestruction is not called from Main.qml when closing the app. It is correctly called from other pages, when pulling the page from a pageStack.
Note: I use last clickable version: 6.24.1 and I did clickable update.

It seems not related to my app, because I did this simple test with clickable create:

• create the template QML app
• create the template C++ app

in both app, in Main.QML, in the page component, just add:

        Component.onDestruction: {
            console.log("Destruction")
        }

When closing the app, I see the log with QML app, and I don't see it with C++ app!

Did you see this behavior? Any ideas how to solve it? or a workaround to do some actions when user close the app?

Thanks @cibersheep for your answers, I succeed to do what I want with Content Hub and a C++ plugin to manage file deletion and renaming.
I wrote a a sample app available here: importwithcontenthub, with many (too much!) comments.
This sample app allow user to import an image, the image is stored (so that it is available on next app launch). And when user imports a new image, it is stored by overwriting the last one (only last imported image is stored).

Yes! it is working with last clickable version (6.23.3).
Thank you @lduboeuf !

@lduboeuf, I have done clickable update, but I see that I have clickable version 6.22.0, so not the last. I will get the last version and try again, may be that's it.
Thanks!

Hi,
I try to run the C++ template app after doing clickable create , it runs correctly on desktop, but on the phone (FP2 with OTA-15, stable channel), it fails: I have a blank screen. With clickable logs, the messages are:

Loading module: 'libubuntu_application_api_touch_mirclient.so.3.0.0'
Creating a QMirClientScreen now
Starting app from main.cpp
qrc:/Main.qml:23:1: plugin cannot be loaded for module "Example": Failed to extract plugin meta data from '/opt/click.ubuntu.com/testcppapp.aloysliska/1.0.0/lib/arm-linux-gnueabihf/Example/libExample.so'
library "/vendor/lib/egl/libGLESv2S3D_adreno.so" not found

and I use here only the original C++ template without any modification.

Any ideas?
