🧩 Key Features
✅ Supports Single & Multiple file selection. ✅ Works with all file types (image, video, audio, documents, etc.). ✅ Uses Storage Access Framework (modern Android API — safer and future-proof). ✅ Returns detailed metadata (name, mime type, size, pseudo path). ✅ Option to persist URI permissions for long-term file access. ✅ No need for “READ_EXTERNAL_STORAGE” on Android 11+ (automatically handled). ✅ Fully compatible with Niotron, Kodular, MIT App Inventor, AI2 clones. ✅ Clean, optimized, and bug-free — no deprecated APIs.🧠 How It Works
This extension uses Android’s ACTION_OPEN_DOCUMENT intent, which is part of the Storage Access Framework (SAF). It does not depend on legacy external storage permissions, ensuring better compatibility with Android 10–14+.After picks file extension fetches:
●Display name
●MIME type
●File size
●Safe, persistent access URI
After Single Pick Return Values Multiple Pick Return Same Values in List
| Property | Example |
|---|---|
| URI | content://com.android.providers.media.documents/document/image%3A4123 |
| Path | content://com.android.providers.media.documents/document/image%3A4123 |
| Name | photo.jpg |
| MIME Type | image/jpeg |
| Size | 2560345 |
⚠️ Limitations
●No real file path: SAF returns secure content URIs, not /storage/... paths. Use ContentResolver streams if you need to read/write. ●Some file managers may not support multiple pick (varies by Android version). ●WRITE access is limited unless file was created or user granted explicit permission. ●Large selections (50+ files) might slow down on low-end devices. ●Intent-based operation — picker opens system UI ( not inside WebViewer ).🧾 Technical Notes
●Works with Android 7+ (SAF introduced in Android 5.0). ●SAF Uris are not direct file paths — use content resolvers or upload via URI streams. ●If PersistUriPermission = true, app keeps access to selected files even after restart. ●maxCount parameter in MultiplePick is for future updates (currently informational).📜 Credits
