The Android based audio and video streaming push method comprises steps as follows: a push terminal collects audio data and video data through an audio collection unit and a video collection unit respectively; the push terminal encodes and compresses the collected audio data and video data through an own encoding unit; the push terminal sends a data push request to the background; the background acquires an identification code of the push terminal, judges whether the push terminal has a push permission and returns permission information to the push terminal; if the permission information indicates 'allowed', the push terminal transmits the compressed audio data and video data to the background for storage. The audio and video streaming collected by an Android mobile terminal can be pushed or played, sharing of audio data and video data is conveniently realized, and the audio data and the video data collected by the Android mobile terminal are shared and subjected to live broadcasting, so that individual needs of users are effectively met.
