Feature Request: Shizuku integration for /Android/data and /Android/obb access

[Calamytryx]

Problem

On Android 13+, teyin cannot access /Android/data and /Android/obb directories despite having MANAGE_EXTERNAL_STORAGE permission. This is a deliberate OS restriction that blocks SAF access to these protected directories.

Current Behavior

• System file picker (SAF) can access these directories
• teyin cannot, no permission option appears to enable it
• No workaround through standard Android APIs

Proposed Solution

Add optional Shizuku integration to enable access to protected storage. This would:

• Allow users to manually enable Shizuku support in settings (optional feature, not forced)
• Follow the pattern used by other FOSS file managers (FV File Manager, SD Maid 2/SE)

Why This Matters

Users need to manage app data directories for:

• Debloating/removing app caches
• Backing up app-specific data
• Managing FOSS app replacements that store data in /Android/data

Device Info

• Device: Xiaomi Redmi Note 15 4G
• Android Version: 16 (HyperOS 3)
• teyin Version: 2026.2

• Android 13 SAF restriction
