    Description

      Code

      import QtQuick
import QtWebView

Window {
    id: root
    width: 640
    height: 480
    visible: true

    property int idx: 0
    property list<string> htmls: [
        '<html><body><h1>Hello, World!</h1><p>This is an example of loading HTML content in a WebView.</p></body></html>',
        '<html><body><span style="color:#ff0000">Hello</span></body></html>',
        '<html><body><span style="color:ff0000">Hello</span></body></html>'
    ]

    Timer {
        interval: 2000
        repeat: true
        running: true
        onTriggered: {
            console.log("Loading index", root.idx)
            webView.loadHtml(root.htmls[root.idx])
            root.idx += 1
            if (root.idx >= root.htmls.length)
                root.idx = 0
        }
    }

    WebView {
        id: webView
        anchors.fill: parent

        onLoadingChanged: (loadRequest) => {
            switch (loadRequest.status) {
            case WebView.LoadStartedStatus: console.log("Loading", loadRequest.url); break
            case WebView.LoadSucceededStatus: console.log("Succeeded", loadRequest.errorString); break
            case WebView.LoadSucceededStatus: console.log("Failed", loadRequest.errorString); break
            default: break
            }
        }
    }
}

      Outcomes

      • Windows loads all 3 pages correctly (Expected)
      • Android fails to load the 2nd page (index 1) (Not Expected)

       

      Windows output:

      qml: Loading index 0
qml: Loading data:text/html;charset=UTF-8,%3Chtml%3E%3Cbody%3E%3Ch1%3EHello%2C World%21%3C%2Fh1%3E%3Cp%3EThis is an example of loading HTML content in a WebView.%3C%2Fp%3E%3C%2Fbody%3E%3C%2Fhtml%3E

qml: Loading index 1
qml: Loading data:text/html;charset=UTF-8,%3Chtml%3E%3Cbody%3E%3Cspan style%3D%22color%3A%23ff0000%22%3EHello%3C%2Fspan%3E%3C%2Fbody%3E%3C%2Fhtml%3E

qml: Succeeded

       

      Android output:

      D qml : : Loading index 0
D qml : : Loading
D qml : : Loading data:text/html;charset=UTF-8,%3Chtml%3E%3Cbody%3E%3Ch1%3EHello, World!%3C/h1%3E%3Cp%3EThis is an example of loading HTML content in a WebView.%3C/p%3E%3C/body%3E%3C/html%3E

D qml : : Succeeded

       

      Notes
      The Windows data URL for index 1 is:

      data:text/html;charset=UTF-8,%3Chtml%3E%3Cbody%3E%3Cspan style%3D%22color%3A%23ff0000%22%3EHello%3C%2Fspan%3E%3C%2Fbody%3E%3C%2Fhtml%3E

       

      The Android data URL for index 1 is:

      data:text/html;charset=UTF-8,%3Chtml%3E%3Cbody%3E%3Cspan style=%22color:#ff0000%22%3EHello%3C/span%3E%3C/body%3E%3C/html%3E

       

      In other words, the Android string doesn't encode '=' and '#'
