Adds a test if a image-url source contains a GIF file

Summary

Today I wanted to show a GIF in a notification an Android 14. I saw that this was added befor two weeks, Sadly this only works with URLs that ends with ".gif". Some URLs don't have the filename in the URL so i added a http header check for that.

Link to pull request in Documentation repository

The Documentation should be fine. The function is already described there.

Edit: I just checked the generated APK on my phone. Now the GIF works fine in notifications also with an URL without the filename.

It looks like this results in the entire image (or whatever is behind the URL) being downloaded. As the image is also fetched later, that is work that should be avoided as it duplicates data used. Try only getting the headers which should contain the content type. This also doesn't handle the authentication required images (hosted on the HA server).

You are right. I commit a "connection.requestMethod = "HEAD" for that.
But what du you mean with "authentication required images (hosted on the HA server)"? I only know direct image paths but these ones should be handled with the filename ending.
Do you maybe mean the use of Image entities? For that this really does not work. But i'm not shure how to resolve this problem. Maybe we could check the file header here?

I now added a byte checkup for the Entity urls. Im not sure if this works good like this, but i will check it with the generated apk!

Because I dont have a image entitiy and i dont now how to add one manually i can't test the byte GIF-check with the image entity. I tryed it with the camera entity, because i used a gif in my camera entity but that doesn't work. Do you now, if the camera entity converts the input somehow? If yes i will delete the camera gif-check.

I think you've misunderstood what I was saying... There is a requiresAuth parameter that should be handled. At this point, paths are never relative because it is transformed here. If you're saying there is no way to serve a GIF from one of HA's built in proxies, that's also fine! No need for these complicated checks I think.
