## What it is
An Android demo application that records the device screen without root on Android 5.0+, optionally capturing microphone audio simultaneously. It uses MediaProjectionManager, VirtualDisplay, AudioRecord, MediaCodec, and MediaMuxer to encode and mux the capture into an MP4 file.

## Use cases
- record android screen without root
- capture screen video with microphone audio on android
- android screen recording demo using mediaprojection
- save screen capture as mp4 on android 5.0+
- learn how mediaprojection and mediacodec work together

## When to choose
- you need a root-free screen recorder on Android 5.0+
- you want a reference implementation of MediaProjection-based capture
- you need simultaneous mic audio recording with screen video

## When to avoid
- you need a production-ready recorder with active maintenance and a license
- you target Android versions below 5.0 without root
- you need iOS or desktop screen recording
