How to Extract and Save Xianyu Videos from Android Cache – Step-by-Step Guide

Introduction

In this guide we show how to download a video from the Xianyu second‑hand marketplace using only an Android phone.

Prerequisite Tools

One Android phone is sufficient.

Step 1 – Open Xianyu

Launch the Xianyu app and navigate to the desired video.

Step 2 – Open the Video

Tap the video to view it, then open the share menu (three dots) and copy the share link.

Step 3 – Locate the Cache Directory

Since the share link does not contain a direct download URL, we retrieve the video from the app’s cache.

Open the file manager, go to Android/data/com.taobao.idlefish/cache/video‑cache. You will see an unnamed file without an extension.

Step 4 – Rename the File

Rename the mysterious file to add a .mp4 suffix.

After renaming, the file shows a proper video thumbnail and can be played normally.

Conclusion

Previously Xianyu offered a direct link copy option, but even without it, extracting the video from the cache and renaming it to MP4 provides a reliable way to download and save the content.
