Hi, I can confirm this happens. I just tried an example app with code from: http://doc.qt.io/qt-5/qtqml-xmlhttprequest-get-qml.html
The 'GetDevices' is revealing, as those calls should have gotten removed from the QtBearer network manager backend, I thought in OTA 8.5

hello everyone I was working on an app that makes use of xmlhttp requests. xmlhttprequest (XHR) is supported in qt qml since way back when. Both GET and POST. I have a working testapp that runs fine on the desktop. But it fails when it is deployed to my phone. It seems apparmor does not allow it: Loading module: 'libubuntu_application_api_touch_mirclient.so.3.0.0' QNetworkManagerInterface::QNetworkManagerInterface(QObject*) propsReply "An AppArmor policy prevents this sender from sending this message to this recipient; type="method_call", sender=":1.862" (uid=32011 pid=23829 comm="/usr/lib/arm-linux-gnueabihf/qt5/bin/qmlscene Main") interface="org.freedesktop.DBus.Properties" member="GetAll" error name="(unset)" requested_reply="0" destination="org.freedesktop.NetworkManager" (uid=0 pid=1698 comm="NetworkManager ")" QNetworkManagerInterface::QNetworkManagerInterface(QObject*) nmReply "An AppArmor policy prevents this sender from sending this message to this recipient; type="method_call", sender=":1.862" (uid=32011 pid=23829 comm="/usr/lib/arm-linux-gnueabihf/qt5/bin/qmlscene Main") interface="org.freedesktop.NetworkManager" member="GetDevices" error name="(unset)" requested_reply="0" destination="org.freedesktop.NetworkManager" (uid=0 pid=1698 comm="NetworkManager ")" "Object path cannot be empty" syslog, however does not show any apparmor=DENIED lines, but contains this for my app: Feb 3 03:10:07 ubuntu-phablet kernel: [56478.996203] type=1400 audit(1454465407.330:1757): apparmor="STATUS" operation="profile_replace" profile="unconfined" name="tstxhttp.matv1_tstxhttp_0.1" pid=27998 comm="apparmor_parser" not sure what that means exactly though. On irc I was advised to do a bug report. However, knowing that this has been a known issue for quite some time and at least one longstanding lp-bug exists, I thought I would ask here first what I ought to do. - On this mailinglist a previous discussion is here: https://lists.launchpad.net/ubuntu-phone/msg14407.html But it is left unconcluded. -the only related bug that I know of is this: https://bugs.launchpad.net/ubuntu/+source/qtbase-opensource-src/+bug/1404188 Now I do not know much about apparmor but I far as I understand the discussion, jdstrand is basically saying that the phone trust model makes it so that for an app like mine to work, it would have to expose networkmanager directly to 'untrusted' apps, which could also expose unwanted things like mac address and such things to those apps. It is suggested that using connectivity-api could help. But I dont quite see how, in scenario's like mine. Also, that bug is still marked as unresolved. So my question is: Whats the status of this? Should I or should I not be expecting XHR to work (now or in the future) on the phone? (Somehow, it seems kinda weird that an app on 'touch' can not use such a common api when any app on any desktop can). Should I perhaps do a new bug report? Please advise, cheers Mathijs
