Request READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE (or MANAGE_EXTERNAL_STORAGE for newer Android versions) to access the media folder.
Internal Storage > Android > media > com.whatsapp > WhatsApp > Media > .Statuses . 2. Development Roadmap (Android)
You can use Python with libraries like watchgod to monitor the folder and shutil to copy the files automatically.
Create a gallery-style view using a RecyclerView or GridView to display thumbnails of the cached videos. 3. Implementation Example (Python for Android/Desktop)
