Office-js: Dialog API sometimes opens two dialogs on Android

[TheSamsterZA]

Expected Behavior

I expect one dialog to open on Android.

Current Behavior

If I open a dialog then close it (by tapping the close button) enough times, I see a second, blank dialog that looks to be stuck at a loading stage.

This does not seem to affect messages from the dialog I intended to open; that is, I open a dialog to my auth provider which redirects back with an auth token, and after I close the blank dialog I can see that my add-in has logged in in the background.

Steps to Reproduce, or Live Example

• Link to live example: https://github.com/TheSamsterZA/office-js-dialog-api-bug

• Additional details:
  
  
  
  1. Sideload the provided manifest
  
  
  2. On Outlook for Android, open the add-in
  
  
  3. Tap Open dialog. A dialog opens pointing to the auth provider.
  
  
  4. Close the dialog by tapping the close button (the 'X' on the left).
  
  
  5. Repeat steps 3 and 4, eventually you should see the second blank dialog.
  
  

Context

In my actual add-in that is currently live on AppSource, I am opening a dialog to a third-party authentication provider. After a successful login on the provider, I am redirected back to my add-in within the dialog. I receive the auth token then programmatically close the dialog from the main taskpane.

After the dialog is closed, seeing a second, blank dialog is unexpected. It will cause much confusion in my clients.

This problem does not occur on Outlook for iOS, Outlook for Windows, Outlook Online, nor Outlook for Mac.

@TheSamsterZA Thanks for reporting this issue.

@exextoc Can you investigate?

Thanks.

@TheSamsterZA , I tried reproducing the problem, if problem reproduces only after successful login, can you please provide test login info to repro this ?

[TheSamsterZA]

@exextoc A login is not required. Simply open the dialog and then close it enough times and you should see what I have come to name the shadow dialog behind the original one.

@TheSamsterZA i tried multiple times but i could not reproduce the problem. do you know any specific condition with which issue is frequently reproducible ?

@exextoc I have a problem that occurs for Android users only as well, i am not sure it is the same problem though.
The issue i am experiencing is that our add-in suppose to make POST requests to my servers and it doesn't do them - instead it just hangs forever.
This issue doesn't occur with: iPhone, Outlook, OWA.

I am using webpack to pack the add-in and axios library (https://github.com/axios/axios) to make the POST request.
The add-in worked over Android devices (and no change has been made since before it stopped working)

Hello @exextoc, please try to replicate now. I can replicate the issue fairly consistently on my Nokia 8 on Android 9 with Outlook for Android 4.0.63 (369).

@exextoc also happens to me.
Android 9 on LG v20 with Outlook version 4.0.57

Thanks for reporting this issue regarding blank dialog. It has been put on our backlog. We unfortunately have no timelines to share at this point
