[android - dialog] Showing any dialog (open / save) does not resolve the underlying Promise the first time

[NyaomiDEV]

Describe the bug

Or in other words, if you open() the first time, nothing happens, and when you open() another time, both promises (first open, second open) will resolve.

This is annoying as hell.

Reproduction

• open() or save() once through a button (this is how I did it)
• await the resulting promise (console.log ?)
• see that it hangs
• open() again
• see both promises resolve at the same time

Expected behavior

Behaviour should be consistent across macOS/Linux/Windows/iOS where it works right the first time.

Wouldn’t that issue be resolved by periodically communicating with the backend? In other words, define a no-op command like the following and invoke it at regular intervals.

#[tauri::command]
pub fn noop() {
   // Do nothing
}

import { invoke } from '@tauri-apps/api/core';
import * as Dialog from '@tauri-apps/plugin-dialog';

async function open() {
  const iid = setInterval(async () => await invoke("noop", {}), 200)
  try {
    return await Dialog.open() 
  }
  finally {
    clearInterval(iid)
  }
}

If this resolves the issue, it is related to tauri-apps/tauri#14994.

Well, it seems to be related...
