+# GB28181 Android Implementation
+
+## Project Introduction
+This is an Android implementation based on the GB28181 standard, primarily used for video capture, encoding, and streaming media transmission. The project uses a combination of C++ and Java programming, including SIP protocol stack implementation and audio/video encoding functionality.
+
+## Main Features
+- Supports GB28181 protocol registration and deregistration
+- Supports audio and video capture and encoding
+- Supports RTSP streaming media transmission
+- Provides complete Android camera preview and recording functionality
+- Includes SIP protocol stack implementation (eXosip2/osip2)
+
+## Technical Architecture
+The project adopts a layered architecture design:
+- Java Layer: Responsible for Android UI and system API calls
+- JNI Layer: Bridges Java and C++ code
+- C++ Layer: Implements the core protocol stack and audio/video encoding
+
+## Core Components
+- `StreamRegister`: SIP stream registration management
+- `MediaEncoder`: Media encoder base class
+- `AudioEncoder`: Audio encoding implementation
+- `VideoEncoder`: Video encoding implementation
+- `CasicMediaKit`: Media processing toolkit
+- `eXosip2/osip2`: SIP protocol stack implementation
+
+## Dependencies
+- FFmpeg-related libraries (avcodec, avformat, avutil, etc.)
+- eXosip2/osip2 SIP protocol stack
+- Android MediaCodec API
