@TischlerWilly I have a similar behaviour with nextcloud...
When I add my account it works fine one time, than later on the update is too fast and nothing is really updated.
I found a workaround.
My Nexcloud account was linked to two or more apps. Now I set an account for each app and it seems to work a lot better.

Hope it can help.

@agrucza I am also creating a prototype for a slack client.

Great idea to contact slack and suggest the creation of a native app.
If any project is started, I would gladly join and contribute.

If I make any progress, I will share my findings with you all.

Regards,

Ok guys, I finally found my mistake, so here is the story.
After too much time spent on this issue, I decided to use the "big gun" to move forward.

So, this weekend I started to create a C++ plugin based on QNetworkAccessManager.
And I did the same error, so I got nothing in return.
Few coding later (after implementing the error management) I had my answer : Host not found !?!

I tried with another HTTPS URI and I got an access denied error...

After a few try I finally understood how stupid I had been.
I forgot to add "networking" in the app apparmor !!!

In fact my many tries and switching from a working app to a WIP app hid the real problem.

But it seems there is a little tricky thing:
When you change apparmor or the app logo, you have to uninstall the app before pushing it again to debug, changes have no effect otherwise...

Many thanks for all the help guys. I'll be more cautious next time

Hi, very good idea.

In my case I have no knowledge at all on how to port UT to another device.

What I need to know to get started is:

• How to identify a device eligible to porting
• What are the tools I need to know to achieve this goal
• A glossary of all the terms, tools, softwares, technologies or other stuff I don't understand.
• The main steps and a methodology on how to get to a full working image.

According to me the first thing required (and the most important) is the glossary.
Most of the time I don't understand a term and I'm not able to search for it because it's not something easy to spot on internet if you don't know what it is...
For example search for ADB without any idea of what it might be (now I know, but it took a while to figure it out when android was first released)

I like the idea of a blog with some videos and screenshots to understand what we are talking about.

The UBPorts documentation is nice, but for graphical items I think it lacks few pictures to illustrate things...

Thanks a lot for all your contributions.

Hi, I promised a feedback.

My first tests weren't successful, I need to work on how to implement the onerror method to have better understanding of my issue.

Thanks again for your ideas

@peterw said in Camera app doesn't work:

or more usually, a message telling me "Camera app doesn't have permission to access the camera hardware or another error occurred. If granting permission does not resolve this problem, reboot your device".

Of course the Camera app has permission as per the system settings, and rebooting doesn't solve the issue.

In my case, the reboot worked with my Nexus5, the problem occurred few times.
Have you tried to remove the cache files before rebooting?

@dobey and @Ingo

Thank you both, I'm looking into the code @dobey posted to implement the onerror so I can go forward.
I'll give you an update tomorrow after spending some time on this.

@dobey I don't know how a specific url will change anything, because it does not work with any https...
The first test I did was for this app :
https://gitlab.com/AppsLee/domoticz-ubports

In this case, the certificate is not ok, so I didn't worry much.
Now I'm creating a client for Slack, so I tried with a genuine HTTPS request (I use the same Request.qml as for domoticz, but now I put some debug code)
The url tested is : https://slack.com/api/conversations.history?token=<myToken>&channel=<myChannelId>
I also tested other HTTPS url : https://www.appliancetherapy.com and https://addons.mozilla.org for example, but none worked, but all of them worked with Morph browser.

In each case I got the same answer: status=0 and readyState=DONE
There no other kind of error message, I don't know what you expect.

To trigger the request I use this:

Component.onCompleted: reqFct.getMessages("https://addons.mozilla.org")

The request is sent by:

function getMessages(url) {
  var req = new XMLHttpRequest();
  req.open("get", url, true);
  req.onreadystatechange = function() {requestItem.readMessages(req)}
  req.send();
} // getMessages()

And the readMessages has been reduced to that:

function readMessages(objReq, refresh) {
  if ( objReq.readyState === XMLHttpRequest.DONE ) {
    if (objReq.status == 200) {
      inputMsg.text += "Answer OK\n"
    } else {
      inputMsg.text += "Answer KO "+objReq.status+"\n"
    }
    inputMsg.text += "YY"+objReq.responseText+"XX\n"
    }
  } else {
    inputMsg.text += "NOT DONE yet\n"
  }
} // readMessages()

In inputMsg, I've got:

Answer KO 0
YYXX

I removed the Content-type just to be sure (I added it hoping it might help) but same result.
I tried various example from the net but nothing solved my issue, that's why I thought maybe I need to enable something or send some magic command to enable HTTPS.

@Ingo thanks for the links, I'll read, try and go back here later this weekend.

My issue is with any https url. I tried with different kind of URL to identify the source of my problem.

@Ingo I checked the values for req.readyState and req.status, req.readyState=4 as expected and req.status=0 wich is bad news ; I expect 200

@haveaniceday Yes, I tested the url from Slack's API in the web browser and I got my JSON answer as expected.
With domoticz https url I've got an error because the certificate is self validated.
That is not my issue.
So the problem is not between my device and the URL.

With HTTP request : everything goes well, so my code seems fine except if something special has to be done for HTTPS requests ; hence my question here...

@Krille The authentication was not required when I tried HTTPS requests (start small, grow big )

@Flohack Yes, I suspected something like that too, but I don't know how to check or fix anything on this side.

Maybe I have to try another method to send my requests ; I mainly send them to request JSON

I'm noob developing for UT, I don't know if I can debug the code executed on my phone ; I use popups and text items to give me hints

Thanks for your answers, I hope to find and answer and that it could help new developers too!

Hi everyone,

I have an issue sending HTTPS requests using XMLHttpRequest().
My code works well with non secure connections but I always have an error when sending the request to secure server.

Here is the code I'm using to send a simple JSON request.

  function callRequest(url) {
    var req = new XMLHttpRequest();

    req.open("get", url, true);
    req.setRequestHeader("Content-type", "application/json");
    if (settings.myAuth != "") {
      req.setRequestHeader("Authorization", "Basic "+settings.myAuth)
    }
    req.onreadystatechange = function() {requestItem.onChange(req)}
    req.send();
  } // callRequest()

Is there something I miss in my usage of XMLHttpRequest() or is there another way to address secured API?
I'm trying to improve my app for domoticz and I first thought it was because of self generated certificate, but then I started another app (a client for Slack messenger) and I had the same issue with HTTPS requests.

I'm beginner in QML and Javascript, but I'm advanced developer in QT/C++.
So maybe my question is one of a noob, but I can't figure it out by myself.

Another idea I had was maybe it requires different rights for the app?
I only set "networking" and I added "push-notification-client" for experimenting a bit.

Regards,
Richard
