This is an AI-assisted analysis of Shizuku-related usages in the app's public source code. It is best effort, so it may not catch every single usage.

How this app uses Shizuku

Shizuku is used to read the Bilibili app's private cached downloads and to export them as playable videos when normal storage access cannot reach them.

• List cached downloads: browse completed Bilibili caches, including titles, covers and episode parts, read through the privileged service.
• Show download details: open one cached title to see its parts, completion state and sizes, loaded through the same privileged read.
• Export videos as files: save a selected cache to a user chosen output as a single playable video, copied or rebuilt with FFmpeg inside the privileged service by merging separate video and audio streams, joining multi part cache segments, or copying a finished file directly, with progress, completion and error callbacks and readable permissions set on the result.

Android APIs or commands used

• java.io.File
• java.io.FileInputStream
• java.io.FileOutputStream
• java.nio.file.Files.setPosixFilePermissions

Notable details

Without Shizuku the app can still list and export using storage access framework folder permission or direct file access when the download folder is readable.
