QtWebView call c++ functions on Android

[yagabey]

Hi All,

I need to call some c++ functions from webview. Using QWebEngineView with QWebchannel was a great option until I realized that QWebEngineView is not supported on Android. So the only thing I have is QtWebView...

I googled for hours, but I couldn't find any answer.

Isn't there any way to call c++ procedures from QtWebView on "Android".

Thanks in advance

Android Studio, the official IDE from Google, is not only java....
https://www.sitepoint.com/using-c-an...-with-the-ndk/

or

https://github.com/search?l=C%2B%2B&...utf8=%E2%9C%93

or QT QXmlQuery mixed...
this is so many way....

QDateTime timer1( QDateTime::currentDateTime() );
    StreamBuf *buf = new StreamBuf();
    QXmlQuery xquery(QXmlQuery::XSLT20);
    xquery.setFocus(QUrl("http://www.qtcentre.org/external.php?type=RSS2&forumids=2"));
    xquery.bindVariable("unixtime", QVariant(timer1.toTime_t()));
    xquery.bindVariable("ddate", QVariant(timer1.toString()));
    xquery.bindVariable("pathinfoapp", QVariant( qApp->applicationDirPath() ));
    xquery.setQuery(QUrl("https://raw.githubusercontent.com/pehohlva/DocSpeacker/master/src/resource/browser_rss.xsl"));
    xquery.evaluateTo(buf->device());
    _doc->setHtml ( buf->data() );
