Project description:
"I’m building an Android‐only app that quietly pulls lecture files from my Telegram channels or groups, stores them locally, and plays them inside its own interface with zero dependence on Telegram once the transfer is complete. After the first sync the user should never notice where the files came from; everything should feel like a native lecture library.

Content management
• During import, files must be tagged or foldered so they appear “By subject” in the library view. If a subject tag is missing you can prompt for one or fall back to an “Unsorted” bucket—whichever is simpler to implement.
• A fast in-app search bar is essential. I should be able to type part of a title or subject and see filtered results immediately. No advanced filters are needed beyond that.

Player & UX
Playback can rely on ExoPlayer or any comparable open-source component. Standard controls (play/pause, seek, skip 15 s, playback speed) are enough. The design can stay minimal; I’m more concerned with clean code and smooth performance than with fancy UI polish.

Sync process
1. User enters a channel link or ID (public or private) and authenticates once, if required.
2. App downloads all media that match a simple rule set (e.g., video, audio, PDF).
3. After download completes, the Telegram session is closed and no live link remains; all files are stored locally (internal storage) and indexed for the search engine.

Deliverables
• Full Android Studio project with source code and Gradle files
• Signed release APK for quick testing
• Brief README covering build steps, required Telegram API keys, and how to add additional channels

Acceptance criteria
– I can import at least one sample channel and see lectures listed by subject.
– Search returns correct items within 1 s on a mid-range device.
– Switching the phone to airplane mode still allows playback of any downloaded lecture.
– No network calls to Telegram (or anywhere else) occur once sync is turned off.

If you’ve previously worked with Telegram’s TDLib, bots, or any offline media apps, let me know—that experience will help speed things up." (client-provided description)
