[bug] Navigate on Android

[dev-mash]

Describe the bug

When starting the app, I want to open the last-viewed-page. This works on desktop. But on android there seems to be a problem with the order/timing. See pseudocode below. Any thoughts on how to implement this properly?

PS: When using async+sleep I can see that the navigation is working. So its not a problem of the navigate() itself.

My Pseudocode:

Starting the app

tauri::Builder::default()
            .setup(|app| {
                load_last_page(app.app_handle().clone());
                Ok(())
            })
            .build(tauri::generate_context!())
            .expect("error while running tauri application");

The function to load the last page (pseudeocode, simplified)

fn load_last_page(appHandle: &tauri::AppHandle) {
  println!("load_last_page Loading last page");
        let main_window = appHandle.get_webview_window("main").unwrap();
        match Url::parse("http://tauri.localhost/mypage") {
            Ok(url) => _ = {
              println!("load_last_page Navigating to the page");
              main_window.navigate(url);
              // tauri::async_runtime::spawn(async move {
              //   tokio::time::sleep(Duration::from_secs(3)).await;
              //   println!("load_last_page Navigating to sleep");
              //   main_window.navigate(url);
              // });
            },
            Err(e) => println!("Failed to parse URL {}", e),
        }
}
