Question

我正在webview上创建应用程序，webview在链接上加载本地html和样式

在Android 4-8上加载CSS，但在android 9上加载CSS

代码：

StringBuilder data = new StringBuilder();
data.append("<HTML><HEAD><LINK href=\"http://example.com/style.css\" type=\"text/css\" rel=\"stylesheet\"/></HEAD><body>");
data.append(bundle.getString("content"));
data.append("</body></HTML>");

webView.loadData(data.toString(), "text/html", "UTF-8");

Answer 1

尝试添加清单

android:cleartextTrafficPermitted="true"

为此已通过android 9网络安全性。阅读：https://developer.android.com/training/articles/security-config

或

<application android:networkSecurityConfig="@xml/network_security_config">

network_security_config.xml

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true">
        <trust-anchors>
            <certificates src="system" />
        </trust-anchors>
    </base-config>
</network-security-config>
