Card image does not change after being set once in HTTP mode

[Fang-]

My server sends card data to relevant clients whenever someone changes their name or display picture. However, it seems that the picture gets stuck at whatever is the first value sent for a specific friend.

Here is the first response my server sends, which contains both the friend's location and their card:

The image from the card correctly shows up in the app for that friend.

Some time later, my server sends the following response, which contains a different name and face for the same friend:

The name updates correctly, but the picture display in the app remains unchanged. Interestingly, the very first image received for a tid sticks around even after removing the friend, restarting the app, etc.

The logs do show I MessageProcessor: Received incoming message: MessageCard on owntracks/http/~lup/testphone, but nothing else of note.

(Yes, the issue persists with the same behavior when using two-character values for the tid.)

[ckrey]

My guess is you confusef the app by using a tid containing a /. This is treated speiually as we use it as a topic level separator in MQTT mode.

And topic should be used consistently. It defaults to owntracks/http/<tid>.

[Fang-]

Thank you for the suggestions. Removing the / from the tid does not resolve the issue for me. For the topic, you're right that I was not providing it consistently, and in maybe the wrong format. I tried with owntracks/http/<tid>, or omitting it entirely (letting the app default) but the problem persists.

To simplify the problem case, I hard-coded the tid and topic values in the response, resulting in the below json. The behavior remains: the name is applied, but the face isn't.

Initial response:

If there's any other information here that would be useful for debugging, please let me know, I'd be happy to provide it. Able and willing to run an instrumented build of the app if that's necessary.

[jpmens]

So the CARD is being processed (the users' name changes), but the face isn't being replaced.

What happens, after the CARD is processed if you restart the app (swipe out, kill, restart)?

Also, please tell us which version of OwnTracks you are using and which Android device / OS.

[Fang-]

What happens, after the CARD is processed if you restart the app (swipe out, kill, restart)?

The old/initial face keeps being displayed. Receiving a new response after full restart continues the same behavior (changing the name, not the face).
