Thumbnail value null for pdf document in setMessageObserver

[Ramaraju1992]

when I receive a new message i added listener like below,

webex.messages().setMessageObserver(
	new MessageObserver() {
		public void onEvent(MessageEvent event) {
			if (event instanceof MessageReceived) {
				Message currentMessage = ((MessageReceived) event).getMessage();
				List<RemoteFile> messageFiles = currentMessage.getFiles();
				RemoteFile messageFile = messageFiles.get(0);
				Log.e("thumbnail value ==> ", messageFile.getThumbnail());
			}
		}
	}
);

Thumbnail value null if I receive new message with document(pdf).
and when I receive Image file, thumbnail value exists.
please refer below screenshots.

@Ramaraju1992 can you please clarify if you are using the Android SKD 2.8 or 3.0 version? Is the issue reproducible with the KitchenSink app: https://github.com/webex/webex-android-sdk-example ?

[Ramaraju1992]

@jbenyovs we are using Android SDK v2.8.0.
and it is still same in Kitchen Sink App too.

And one more Observation is when i try to send .tiff formatted image files bitmap value is null even from webex.messages().list.
