How to play media with my own media player as default

I am an Android developer. I've developed a media player that can play both local and streaming videos. But there is a problem. When I click a local media in the gallery how can I configure it to be played with my player? At least, there should be a list of media players including mine one and I should be able to choose it from this list. After succeeding this, I want to open 开发者_JAVA技巧rtsp protocoled files with my player as default. How can I do this? Waiting for your help.

What you are looking for is called an Intent Filter. Specifically, you want to set up an intent filter on the type of media you are playing, a data type intent filter. There is more information on this in the Android SDK.
