Hi,
I am developing an application where I basically download a video file and show it in the HistoryActivity. My video model has name, authorName, authorImageUrl, videoDescription and every time I download a video, I store the video info in the SharedPreference so that I can list all the videos with their description in the HistoryActivity. I am using video’s name property as an ID to connect the video with its description I stored in the SharedPreference. However, when user changes the name of the video using other apps, I am losing the ID.
So the question: Is there any way that I can use as an ID for video file or any other file type?

without getting too far into the question of what you want to consider, "identity" for a video, it sounds like you're defining video identity to be an entry in your downloaded files record. You want the metadata to be able to change without affecting the identity, though the bytes on disk and the filename of the bytes on disk are probably not going to change. If the user deletes a file and redownloads it, that's a "new" video, from your description.

so you can probably generate a random UUID and store it alongside the name and other metadata, then always refer to a video by its uuid, not by its name. The uuid will never change for a given downloaded file.

Hmm, good point, I see it now 🙂 thanks.
