Restoring Android Activity playing media

I'm working on a project that includes a media player. All is going fine, I select the media to be played from a play list and send it to the player activity and press play. The audio plays just like it should. Now, when I leave that activity (with the audio still playing) I'm unable to get back to that same activity, clicking the same item from the playlist starts a new activity with 开发者_如何学Gothe old media playing in the background still. How can bring back an old activity?

I don't get your question at all. However, look at the state diagram here:

And the other state diagram here:

Combine the MediaPlayer states and the Activity states in order to fulfill your need.
