Question

The message content sent by the incoming webhook is empty, on the Android Teams app.

Hzzzzz 20

Hello Teams Community,

After updating to the latest Android version in August, I found that the content was empty. My code hasn't changed.

The content of historical message has also become empty, It was normal at that time( June ). The mentioned function in the content is effective.

This is my current Android version of Teams.

The same message can be displayed normally on the client for Mac, iOS, and chrome browser. User's image

Maybe it is a compatibility issue from new version. Please solve this problem.

Thanks.

@Hzzzzz - Could you please share the message content JSON so that we can check it from our end?

Here are two simple demos, both of them can reproduce the problem.

fetch('webhookUrl', {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    "@context": "https://schema.org/extensions",
    "@type": "MessageCard",
    themeColor: "0072C6",
    title: "Title",
    text: "Text",
  }),
});

fetch('webhookUrl', {
  method: "POST",
  body: new Blob(
    [
      JSON.stringify({
        type: "message",
        attachments: [
          {
            contentType: "application/vnd.microsoft.card.adaptive",
            contentUrl: null,
            content: {
              $schema: "http://adaptivecards.io/schemas/adaptive-card.json",
              type: "AdaptiveCard",
              version: "1.5",
              body: [
                {
                  type: "TextBlock",
                  weight: "Bolder",
                  text: "Title",
                },
              ],
            },
          },
        ],
      }),
    ],
    { type: "application/json" }
  ),
});

We tried to repro this issue using the card JSON provided and observed the same behaviour.
Card is not getting rendered in Teams Android while sending via webhook.

Teams version:

It gets rendered in Teams desktop/web client. User's image

We have raised a bug for the same. We will inform you once we get any further update from engineering team.

Thanks,

Update:

Hzzzzz, using below adaptive card JSON schema it renders correctly in Mobile devices.

{
    "type": "message",
    "attachments": [
        {
            "contentType": "application/vnd.microsoft.card.adaptive",
            "content": {
              "body": [
                {
                  "type": "TextBlock",
                  "weight": "Bolder",
                  "text": "Title"
                }
              ],
            "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
            "version": "1.3"
            }
