Based on market demand, IPTV based on Android also came into being. Designed for mobile phones, Android operating system does not support live streaming IPTV service, aspects on demand, playback control, media packaging and multi-screen interaction requirements. Therefore, under full consideration to the needs of the current business situation, IPTV project team proposed streaming media player needs based on Android. This paper including current development of streaming media technology, based on software reuse as the background, analyzes the current situation and development trend of the Android platform to support the current expansion, and network multimedia applications to the main stream media technology, summed up the current IPTV system for streaming media player requirements. Android worry about without changing the system architecture and are not issued in conflict with the native player, the layers defined in the system software needed to expand the functionality and the corresponding interface, support for new business functions. Insufficient to make up the difference between the existing Android player is not compatible with all protocols shortcomings and playback quality. This paper focuses on the streaming media technology in two areas: real-time streaming audio and video transmission and resolution. On this basis, the layers defined in the system software needed to expand the functionality and the corresponding interface, support for new business functions. This paper uses the Java and C language to develop streaming media player, according to the system design requirements, propose a general framework for the system, the system will achieve is divided into user interfaces, messaging sessions, audio and video dat
