# Floating Picture-in-Picture and Background Audio

Many students need to take notes in external PDF readers, solve coding problems
in web editors, or consult physical textbooks while listening to a lecture.
Quietube provides powerful multitasking tools via Floating Picture-in-Picture
(PiP) and Background Audio.


FLOATING PICTURE-IN-PICTURE (PIP) OVERLAY

Quietube features an in-app and system-level draggable PiP overlay:

 * Seamless Transition: Swipe down on the video player or navigate to another
   tab inside Quietube, and the video shrinks into a compact floating window in
   the corner of your screen.
 * Draggable & Resizable: Drag the floating window to any corner of your screen
   so it never covers the text or questions you are currently solving.
 * Quick Controls: Play, pause, or expand back to full player view with a single
   tap on the floating tile.


BACKGROUND AUDIO PLAYBACK & LOCK-SCREEN CONTROLS

When listening to podcast-style lectures, history documentaries, or language
seminars, you can lock your screen or turn off the display to save battery while
audio continues playing seamlessly:

 * Native Media Notification: Quietube coordinates with Android's MediaSession
   architecture, displaying a clean media playback card on your lock screen and
   notification shade.
 * Lock-Screen Actions: Play, pause, and seek without unlocking your device,
   protecting you from accidental notification distractions while listening.
