        note that the idea of using BT sharing instead of BT plugin is a suggestion, I think (personal opinion) it's better than 'BT plugin', but it's not necessary the best idea.

        Understood -- I created the issue to make sure it doesn't slip my mind. If better suggestions are offered, they are welcome!

        Also reading them reminds me that I could take a look at the confined problem. This said, it seems that the mere fact of using 'bluetooth' makes this application something to be vetted, even if it's confined.

        Correct.

        I don't know why, given that unrestricted applications can access Internet and (I think) the local network, it seems to me to be a risk even greater than bluetooth πŸ˜‰

        In theory, unconfined applications are simply forbidden, as they could do almost anything (that the user they run as could do). I'll try to contact the review team on Telegram to get the review process started. Without that, I can't distribute the .click packages on the OpenStore.

          Err, I wanted to wrote 'restricted applications can access Internet'. But it don't matter much.

          Anyway, I tried to regenerate the click without the unconfined template. Now, the confined app can send files to the Android phone without problem at all. It's in the other direction that I get an authorization error:

          fΓ©vr. 19 10:28:19 ubuntu-phablet obexd[3879]: Agent replied with an error: org.freedesktop.DBus.Error.AccessDenied, An AppArmor policy prevents this sender from sending this message to this recipient; type="method_call", sender=":1.0" (uid=32011 pid=3879 comm="/usr/libexec/bluetooth/obexd -P ftp,irmc,mas,pcsui" label="unconfined") interface="org.bluez.obex.Agent1" member="AuthorizePush" error name="(unset)" requested_reply="0" destination=":1.116" (uid=32011 pid=7190 comm="ratatoskr" label="ratatoskr.petroniusniger_ratatoskr_0.1.0 (enforce)")
          

          Now I don't think anymore that it's a matter of setting the system to grant the authorization. You see, in the other direction on the Android phone I get a prompt to authorize the transfer. The UT phone can't simply push files to the Android phone without any user interaction.
          And I think that this should be the fix: that somehow the UT user (phablet) get a prompt to grant the other system the (temporary) right to write the file to the UT destination.
          Granted, I don't have currently the slightest idea on how to proceed from that πŸ˜‰

            The MR got merged by the way. Now it's in 24.04-2, not in the stable version.

            I could ask in the appropriate thread to sneak this change in the 24.04-1.2RC3 if there is any (don't seem likely). Or maybe you could ask yourself since it's your app ?

              Yes, I'm aware of this -- I already reported this higher up in this thread. The SharePlugin works fine with a confined AppArmor profile. It's only the main app that needs wider rights to interact with D-Bus / OBEX.

              Now I don't think anymore that it's a matter of setting the system to grant the authorization. You see, in the other direction on the Android phone I get a prompt to authorize the transfer. The UT phone can't simply push files to the Android phone without any user interaction.

              Having a prompt for the user to accept the incoming transfer is indeed needed (and already tracked through issue #6), but I don't see this as related to the fact that a confined AA profile prevents the app from issuing the "AuthorizePush" message.

              This clearly needs further investigation.

                I've hit a snag. I'm supposed to contact the review team on Telegram to try and get my app approved for publication on the OpenStore, but it seems I can't create a Telegram account through the UT Teleports app -- it says the official Android or iOS app is required to do this, which I don't have access to.

                I'll try to contact 'bhdouglass' via the forum instead.

                      if the obexd issue can be solved at platform level, the app could be ported to 24.04 with minimum effort.

                      as they say in open source, 'unfortunately' the MR was backported to the 24.04-1.x too late to be included in the 24.04-1.2 version 😞 . That means that your app will not work at all in this version unless some system fiddling is done by the user.

                          So this means waiting for 24.04-2/stable, I guess...

                            or 24.04-1.3, whatever comes first. I'd bet on 24.04-1.3 but who knows?

                            as a status update, my available bandwidth has been dedicated to try to find a solution for the dbus rights problem (I have again flipflopped in my opinion about this matter, I have seen in the app code where it was supposed to prompt the user and instead it is always answering 'yes').
                            However Apparmor is not the easiest thing in the world to configure, so far I had no success.

                            about the confined apps being forbidden, there are in fact quite a few unconfined apps in the store, most of the ones I know of are managed by 'core' developers, but not all - as far as I know PureMaps is not maintained by a core Ubuntu touch developer; so it's mostly a matter of trust.
