我有一个html文件,我在android studio中的webview中运行它,但它不与www.example.com连接socket.io,html文件没有问题,因为相同的文件在计算机上连接。
这是我的HTML文件:

<!DOCTYPE html>
<html>
    <head>
        <title>Leaflet Popup Example</title>
        <meta charset="utf-8" />
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
        <link rel="stylesheet" href="./leaflet/leaflet.css"/>
        <script src="./leaflet/leaflet.js"></script>
        <script src="./socket_io.js"></script>
    </head>
    <body>
        <div id="mapid" style="height: 100vh;"></div>
        <script>
            var socket = io("http://xxxxx:3000");

            var mymap = L.map('mapid').setView([39.9042, 32.6227], 5);

            L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
                attribution: '&copy; OpenStreetMap contributors'
            }).addTo(mymap);
            var placedMarkers = [];
            socket.on("clientLocations", (data) => {
                placedMarkers.forEach(function(placedMarkers) {
                    mymap.removeLayer(placedMarkers);
                });
                placedMarkers = [];
                markers = data;
                var bounds = [];
                for (var i = 0; i < markers.length; i++) {
                    var marker = L.marker(markers[i].location).addTo(mymap);
                    placedMarkers.push(marker);

                    var popup = L.popup({
                    autoClose: false,
                    closeOnClick: false,
                    closeButton: false,
                    }).setContent(markers[i].name);

                    marker.bindPopup(popup).openPopup();
                    bounds.push(markers[i].location);
                }

                mymap.fitBounds(bounds, { padding: [100, 100], maxZoom: 100 });
            });
        </script>
    </body>
</html>

这是我的Kotlin代码:

val webView: WebView = findViewById(R.id.web_view);
webView.settings.javaScriptEnabled = true;
webView.loadUrl("file:///android_asset/html/index.html")

我有这些权限:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

我补充道

android:usesCleartextTraffic="true"

到**AndroidManifest.xml**文件中的应用程序标记,问题解决。
