QML WebView access camera and microphone

[Marek]

Hi

I'm working on an app which should display webpage with JS library for webRTC connection. It works on Desktop when I'm using WebEngineView. It also works when on Android when I visit the page from chrome browser (it asks whether it can use camera and mic). It doesn't work on Android when I use WebView because I can't access camera and mic.
From what I understand WebView is using native platform browser engine, so if the web browser on Android works, what is the problem with WebView ? Is is simply some functionality that has been written yet? Will this be written? I can't see any changes to this in 5.10 release, although Qt WebEngine has some new features. Or worse still is it some policy that on mobile platform I can't access camera and microphone from WebView and JS library for webRTC won't work?

Best Regards
Marek

@Marek
just a quick guess: Did you enabled the correct permissions to your app for mic and camera usage?

Hi
I have this in AndroidManifest

<!-- The following comment will be replaced upon deployment with default permissions based on the dependencies of the application.
         Remove the comment if you do not require these default permissions. -->
        <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />


    <!-- The following comment will be replaced upon deployment with default features based on the dependencies of the application.

        <uses-feature android:glEsVersion="0x00020000" android:required="true" />

<uses-permission android:name="android.permission.CAMERA"/>
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.RECORD_AUDIO"/>
    <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/>

Paragraph at the bottom are permisstions added in Qt Creator.
I wonder maybe this is somehow Android version issue I have 4.2.2

From what I know, if I go back to Qt 5.4 with WebKit then app won't be accepted in AppStore or GooglePlay as they require that all applications displaying web content use their native web engine. Right?

[raven-worx]

@Marek
yes

[Marek]

So, anything more about WebView, is it really a wrapper around native web engine (for Android android.webkit.WebView) ?
And since native webengine allows the use of camera and mic, then it should be possible to persuade QML WebView to allow camera and mic ?

@Deepak_Patel
no sry, my experience with iOS is almost zero.

@Deepak_Patel I think it is impossible on iOS. Qt WebView is based on WkWebView
