Hi @Yugandhar159 - Thanks for sharing the sample manifest. However, we need more details such as sample code used and repro steps to investigate further.

@Prasad-MSFT
We are using simple download on click on button i will call API and Down load File

code snippet for download
let contentType = 'application/json;charset=utf-8;';
var a = document.createElement('a');
a.download = filename;
a.href = 'data:' + contentType + ',' + encodeURIComponent(JSON.stringify(objectData));
a.target = '_blank';
document.body.appendChild(a);
a.click();
document.body.removeChild(a);

We checked using this sample. (https://github.com/OfficeDev/Microsoft-Teams-Samples/tree/main/samples/meeting-recruitment-app/csharp) The file download functionality works fine in Teams Desktop/Web client. However, when we checked in mobile client (Android) it shows below error:

Could you please check with the deployed demo manifest and let us know if you are also facing the same?

[Yugandhar159]

Yes we are also facing the same issue
