Is the proxy_url unavailable on Android?

[Borber]

Describe the bug The proxy setup code for the Android WebView is not functioning correctly

Steps To Reproduce

pub async fn run() {
    common::init().await;

    tauri::Builder::default()
        .setup(|app| {
            let win_builder = tauri::WebviewWindowBuilder::new(
                app,
                "main",
                tauri::WebviewUrl::External(Url::parse("http://test1.genmeta.net")?),
            )
            .proxy_url(Url::parse("http://192.168.31.86:5379")?);

            #[cfg(target_os = "macos")]
            let win_builder = win_builder
                .title("Gapp")
                .inner_size(1000.0, 800.0)
                .title_bar_style(tauri::TitleBarStyle::Transparent)
                .center();

            let main_window = win_builder.build().expect("failed to build window");

            info!("window created");

            Ok(())
        })
        .plugin(tauri_plugin_opener::init())
        .invoke_handler(tauri::generate_handler![greet])
        .run(tauri::generate_context!())
        .expect("error while running tauri application");
}

Since test1.genmeta.net is our local network domain, it is currently not accessible.

Expected behavior

Android webview can use proxy

correct: https://docs.rs/wry/latest/wry/struct.WebViewBuilder.html#method.with_proxy_config - i do not know if there are reasons for that or if we just didn't get to it so i'll leave this open for now.

I ultimately chose to manually add a proxy to the Android code. The code is as follows:：

import android.util.Log
import androidx.webkit.ProxyConfig
import androidx.webkit.ProxyController
import androidx.webkit.WebViewFeature
import java.util.concurrent.Executor


class MainActivity : TauriActivity() {
  override fun onStart() {
    super.onStart()

    if (WebViewFeature.isFeatureSupported(WebViewFeature.PROXY_OVERRIDE)) {
      val proxyConfig = ProxyConfig.Builder()
        .addProxyRule("http://127.0.0.1:5380")
        .addDirect()
        .build()

      ProxyController.getInstance().setProxyOverride(
        proxyConfig,
        Executor {
          //do nothing
        }
      ) {}
    }
  }
}

But I still hope to support Android to set up directly through proxy_url
