我正在使用 Kotlin 和 Jetpack Compose 创建一个 Android 应用程序，我有一个显示 Web 视图的可组合屏幕。
屏幕说明
需要什么？
这是Redirect Url的模式

我在这里缺少的任何帮助，即不允许我的应用程序接收重定向网址，而是在用户的网络浏览器中打开重定向网址。
您还没有在您的应用程序和网站中正确设置深层链接。
如果您不希望链接在外部网络浏览器中打开，您需要将 https://yourdomain/.well-known/assetlinks.json 与以下内容放在一起。
[{
"relation": ["delegate_permission/common.handle_all_urls"],
"target": {
"namespace": "android_app",
"package_name": "your_com.example",
"sha256_cert_fingerprints":
["YOUR_CERTIFICATE"]
}
}]
注意：您可以从此 URL 创建上述文件： https://developers.google.com/digital-asset-links/tools/generator
您可以使用以下命令生成应用程序的 SHA256 指纹：
keytool -list -v -keystore <keystore path> -alias <key alias> -storepass <store password> -keypass <key password>
