Getting crash when adding a WebView to my Page
-
I am trying to add an
Ubuntu.Web.WebViewto a test app based off the clickableut-app-cmake-templatefrom the clickable getting started page. This gave me a simple hello world app. Now I am trying to add a WebView.
This gives me:import QtQuick 2.4 import QtQuick.Layouts 1.1 import QtQuick.LocalStorage 2.0 import Ubuntu.Components 1.3 import Ubuntu.Connectivity 1.0 import Ubspotplugin 1.0 import Ubuntu.Web 0.2 MainView { id: root objectName: 'mainView' applicationName: 'ubspot.mungorae' automaticOrientation: true width: units.gu(45) height: units.gu(75) Page { anchors.fill: parent header: PageHeader { id: header title: i18n.tr('UBSpot') } WebView { id: webView url: "http://www.google.com" anchors { left: parent.left right: parent.right bottom: parent.bottom top: loginPage.header.bottom } incognito: true preferences.localStorageEnabled: true preferences.allowFileAccessFromFileUrls: true preferences.allowUniversalAccessFromFileUrls: true preferences.appCacheEnabled: true preferences.javascriptCanAccessClipboard: true } } Component.onCompleted: Ubspotplugin.speak() }But its crashing with:

Thanks for your consideration.

Hi @mungorae ,
as test i have created a sample app with clickable - -init and template [2]: cmake - C++/QML App, added a WebView like your one and using "clickable --desktop" i have no issues (i have only removed import Ubuntu.Connectivity 1.0 ).
But, looking around i have found this: https://stackoverflow.com/questions/52415263/crash-when-using-webview-on-ubuntu-touch-xenial#
Seems you are the author of that question... As you say in the question you are building/running an App for exenial (16.04) but in your manifest file you have: "policy_version": 1.3 which is a wrong value.
Look here for info about how to update manifest and apparmor files to build app for xenial: https://forums.ubports.com/topic/1215/updating-apps-to-16-04
Then try with: "clickable - -xenial" or "clickable --xenial --desktop"
I'm not sure this solve the issues but i hope can help

haha yeh I am indeed the author of that question. Hadn't found this forum at that time
Thank you for your reply @fulvio.
So I updated my policy version and changed the framework as per the helpful post you linked to. However I do still seem to be getting the same error. My policy file now looks like:{ "policy_groups": [ "networking", "connectivity", "content_exchange", "content_exchange_source", "usermetrics", "webview", "keep-display-on", "audio", "video" ], "policy_version": 16.04 }I am using
clickable ---k 16.04to run it on a Nexus 5 device.From that post I can see mention of a click-review tool, so I installed that and tried to fix any problems. It wanted me to remove debug from policy, so I did that. Now it tells me:
Warnings -------- - lint:architecture_specified_needed Could not find compiled binaries for architecture 'armhf' build/ubspot.mungorae_0.1.0_armhf.click: FAILMaybe that has got something to do with my crash.
If its any help the output of

@mungorae please see this https://forums.ubports.com/post/12942 to get the full picture of what's going to happen

Hi @mungorae
to run the application (not deploy it) on desktop try a:
clickable - -xenial - -desktop
(or: clickable - -desktop )
should works (See Getting started section: http://clickable.bhdouglass.com/en/latest/getting-started.html)
Looking at your last posted output, your app is package successfully as .click package and deployed on your connected phone; so that should run also on desktop.
(Note: you can RUN the app on the desktop without any device connected; but you can't deploy it on desktop; ".click" package is not supported is only for mobile device).
