Hi,
Just to share my experience for developping Apps with QtCreator:
( A rewrite from https://gist.github.com/lduboeuf/dcf22607207d5b7abc8ac966d20942ce )

To get Ubuntu.Components recognized by QtCreator:

• If you work on Ubuntu (16.04-18.04) :

## Get public Ubports key
wget -qO - https://repo.ubports.com/pubkey.gpg | sudo apt-key add -

##add ubports repository
sudo add-apt-repository "deb https://repo.ubports.com/ [bionic|xenial] main"

##install Ubuntu.components
sudo apt install qml-module-ubuntu-components

##qml components should be installed in "/usr/lib/x86_64-linux-gnu/qt5/qml"
##set the environnement variable to profile
echo "export QML_IMPORT_PATH=/usr/lib/x86_64-linux-gnu/qt5/qml" >> ~/.profile

##reload env or you might need to logout/login
source ~/.profile

• A more generic solution using clickable image:

##run container clickable
docker run -i -t --entrypoint /bin/bash clickable/ubuntu-sdk:16.04-amd64

##in an another terminal, get the container id
docker ps

##copy ubuntu components to local folder
docker cp [container id]:/usr/lib/x86_64-linux-gnu/qt5/qml/ /your/local/directory

##set the environnement variable to profile
echo "export QML_IMPORT_PATH=/your/local/directory" >> ~/.profile

##reload env or you might need to logout/login
source ~/.profile

##stop container
docker stop [container id]

• Or running QtCreator in a docker container based from clickable image:

example here: https://github.com/lduboeuf/ut-qtcreator , use branch "add module" branch for installing also some UT qml modules

EDIT: Now clickable provide a Qtcreator IDE with clickable ide qtcreator command

Hi all,

I've managed to try adding an alternate pin code prompt based on that work: http://guidopallemans.blogspot.com/2013/09/some-time-ago-i-saw-beautiful-lock.html

As stated here: https://github.com/ubports/ubuntu-touch/issues/1940
One of the task is to add to security system setting a toggle to select the pin code prompt:

And a demo "tester" to be familiar with this new way:

I've pushed an app click demo here: https://open-store.io/app/lockertest.ld
download:( https://open-store.io/api/v3/apps/lockertest.ld/download/xenial/all )

Any feedback welcome.

( For a demo of this pin code prompt integrated in Lomiri: https://user-images.githubusercontent.com/11663835/154673358-5c7c1cfe-f7ce-4d66-98de-e108cd4fba16.mp4 )

Well, my first native app just landed on Openstore. https://open-store.io/app/ttbn.lduboeuf
I've only used QQC2 components and imported needed svg icons from suru theme.
I admit that as a QML beginner, it was sometimes hard to make things work and displayed correctly... color theme is still not that good.

But i'm happy that i can now build for multi os and still use QtCreator.
Thanks for all your examples

@Mystic-X hello, i'm working on it, will land hopefully soon, at least for having a birthday field on the contact app

Hello all,

I've started to have a look on the Cell Broadcast feature.
The first step we can have is to just display a Notification for Emergency one, but we need to think to implement the full feature.

there will be several levels of alerts and types.
Level 1: Critical, the notification should use a "critical" alert sound along with a persistent popup.
Level 2: Extreme, attention alert sound with persistant popup
Level 3: Severe, attention alert sound with persistant popup
Level 4: Public Safety: attention sound with ephemeral popup
Amber ( child abduction): attention sound with ephemeral popup
Tests: attention sound with ephemeral popup

So the question for now is: Which icons to use, security-alert ?
, and we would need to add specific Alert Sound ( critical + others). Which one could be used ?

hi,

I've been working in re-enabling the Sticker feature in messaging-app (MMS).
Here are some screenshots:

To access it, i've decided to put the "Sticker" icon as part as the attachment panel. Before it was inserted just after the "attachment" icon, but find it a bit annoying to access it.

To create a new pack, the "+" button is on the right of the tabs

To import and delete the pack, the buttons are at the bottom-right
To delete only one sticker, long-press on it

Any feedbacks ?

Hi all, trying to work on the Cell-Broadcast feature.
I'm writing here just as a shared note...

First step could be to implement only Emergency Alerts.

That would need a persistent Notification if possible with a specific sound ( see https://forums.ubports.com/topic/7794/cell-broadcast-story-ui/8), a notification in the messaging indicator and a way to read it later.

We should also have a toggle in settings to enable/disable the feature.
I know some country are even making the option mandatory.
Question here: Should that option be in notification category or in cellular related things ?

As that behaviour is almost like a classic sms, i'm planning to use the current Telepathy Framework by just doing some tweaks ( define a constant sender, MessageType of ChannelTextMessageTypeNotice ).
Define a fake Contact that have the "warning" as the avatar so that it can be recognized in the messaging-app and popups/notifications.
We are lucky to have already the phone part, Ofono expose a Dbus interface for CellBroadcast ( not tested yet )

The work will involve work in telepathy-ofono, telephony-service, history-service (not sure)) , system-settings, gsettings-ubuntu-touch-schemas for the alert sound ).

telepathy-ofono: Takes inputs from ofono cellbroadcast signals ( https://github.com/ubports/ofono/blob/xenial/doc/cell-broadcast-api.txt ). Currently there are notifications for the ETWS system (EmergencyBroadcast signal) and another for all other channels (IncomingBroadcast).
My idea here is to merge the 2 signals and send toward Telepathy a TextMessage with the sender identified as "x-ofono-cellbroadcast", the Subject as the channel topic, type of message of ChannelTextMessageTypeNotice, and the body of the alert in text property.

telephony-service: Listen to Telepathy incoming TextMessage, when message == ChannelTextMessageTypeNotice, sender is "x-cellbroadcast-alert" , and according to Subject, we should display a notification with the corresponding sound.
Different levels of warning are here dependent of the Subject.
The alert is also displayed in the message indicator, and a way to open messaging app to see it again.

history-service: Listen to Telepathy incoming TextMessage ans stores the alert as a message ( message could be of type MessageTypeInformation)

messaging-app: The alerts are gathered into a Thread, the notification icon could be the "broadcast icon", and messages can be styled differently according to their Subject ( channel ).

system-settings: Subscribe to channels, toggles to the different type of broadcast

e.g on Android:

Currenlty Xenial telepathy-ofono uses a libofono-qt version which does not include the Cellbroadcast API => See with Team

Hi,

As you know, since the beginning of UT, when Cellular Data is off or if any issue regarding the MMS download, the MMS will be lost, no way to retrieve it later and moreover no notification is sent to the user.

The complete feature need some skills that i don't have but as a quick fix, i managed to forward any issues as a normal MMS but empty so that user is at least notified something went wrong.
see:
https://github.com/ubports/nuntium/pull/3, https://github.com/ubports/telephony-service/pull/13, https://github.com/ubports/messaging-app/pull/248
It works!

My question is: should i spent effort to continue doing that "work around" or is someone ready/available to do a more complete scenario (when MMS error: retry or notify, implement deferred download, only download if user allowed to, etc... ) ?

In case it is a better than nothing solution , what would be a good message to display to user ? ( note that it will be received as a sms )

Or if any simpler solution, like just displaying a notification( only one place to maintain )

[Edit]: Thanks to the huge work of @jezek we can now be confident with MMS. please test it :

Hi,

We need your help testing a new feature brought by @jezek regarding MMS and the ability to re-download the MMS afterward (if any failure or the cellular data was off when the MMS was received).
Please report here any issue found or success. ( Note that this feature will not correct any APN setting issues, or issues with the provider or device specific )

For the long story: https://forums.ubports.com/topic/5100/the-mms-lost-story

You need to be on devel or RC ( since 2021/06/09 )
From a terminal, run that commands one by one:

sudo ubports-qa install PR_nuntium_8
sudo ubports-qa install telepathy-ofono 20
sudo ubports-qa install history-service 35
sudo ubports-qa install telephony-service 20
sudo ubports-qa install messaging-app 260

And reboot

Test Plan example:
Make sure it works as before, send/receive MMS, multiple ones
Disable cellular-data, receive a MMS and check if MMS notification is here with the download button
Change proxy settings in APN or put wrong settings and check for notification reception

@safalbk said in howt create ubuntu touch app from qml quick project in qt creator(using qml 6.3.1):

@cliffcoggin yes

1. how to create a .click package from qt quick project. for example https://github.com/safalbk/qml/tree/main this is a project that use qt 6.3.1, how i convert this project into Ubuntu touch app

If it helps( note that it is a bit outdated and syntax may have changed, but the overview is still fine ) :
https://m.youtube.com/watch?v=ehqlwRNrfO0 (qmake)

https://m.youtube.com/watch?v=c2sq6aLeGec ( cmake )

Note that UT uses Qt 5.12 so some QML imports should be downgraded

I would recommend starting with a clickable template ( clickable create ) and adapt with your existing code.

@kristatos Hopefully it will be integrated in UT before December.
This is now in the Ubports team hands.
I can guarantee that all UT components are ready to handle Cell Broadcast messages. But there is still an unknow part which is hard to test without a real situation.

@fizz
@jezek did a work that is currently in review that may help fixing or understand better what is going on. Hope it will land on next OTA
It is already testable if you are in devel channel:
sudo ubports-qa install PR_nuntium_18

https://gitlab.com/ubports/development/core/nuntium/-/merge_requests/18

@fizz
nuntium.log would help ( beware phone numbers inside ).
But i remember having issues on N5 when wifi + cellular data was on ( needed to switch off wifi when it happened in order to fetch the MMS)

Do you have the "Download" button or a plain error message only ?
Are you on 4G ?

Btw: note that debugging and working on such issues need a lot of time. And it can have so many causes that it is hard to spot.
Moreover this is not a general issue. MMS is working fine for many people.

Feature integration summary here:
https://github.com/ubports/ubuntu-touch/issues/2003

Hi,

With the Cell Broadcast feature, i'm looking for 2 notifications sound that we will add to UT.
One will be for emergency situation ( something noisy ) and the other less intrusive but still enough to alert user.

Thanks for your proposition

@moem yes, that is the point. There is only few providers that offers MMS in their plan now. So slowly dying, but no standard replacement though, need to use a third party service...

@kantros sadly nobody take that task.
Most active developers here don't even use MMS, so it might explain why...
The feature is partly implemented. At least i think you can send to a group. Idk if they will receive it as a MMS group though.

@messayisto OTA-24 if it does not break everything and the reviewer have time to look at it

So if anyone can propose a default Emergency sound and a less "noisy" one, would be awesome
For the icons, we could use the default warning. And maybe play with colors ( Red/Orange/Yellow) according to levels of alert.
