getAttachmentContentAsync does not invoke callback on android app

[eneoli]

Expected Behavior

The passed callback should be called, like on other platforms like OWA or Outlook Desktop

Current Behavior

The callback doesn't get called using the Add in with the Outlook android app. Using the exactly same code on OWA or Desktop works perfectly.

Steps to Reproduce, or Live Example

Office.context.mailbox.item.getAttachmentContentAsync(id, () => {
console.log('callback called');
});

Tested on two android phones with Android 9

Context

Passing attachments from mail to our web app (Read mail)

Your Environment

• Platform [PC desktop, Mac, iOS, Office Online]: Android App
• Host [Excel, Word, PowerPoint, etc.]: Outlook
• Office version number: latest app version from Play Store
• Operating System: Android 9
• Browser (if using Office Online): X

Useful logs

No errors, no warnings, nothing. Seems like the callback just not gets called.

Is it possible, that the callback is not called because of Office.context.mailbox.ewsUrl not available on Android?

@eneoli right now, Outlook mobile only support API level requirement set 1.5. So this API is not supported as of now in Outlook Mobile(Android or iOS).

@eneoli we recommend you to check for this requirement at runtime and when supported on such platform your code will just work.

It is not just an Android problem. Our getAttachmentContentAsync code to read attachments works perfectly in Outlook Web, but the installed Outlook throws an error: "the operation is not supported"
