add and fix problem my app only people skilled

I only ask for capable people who have already spent money without fixing anything. 1) look at the attached files I need to insert a player compatible with shoutcast and icecast below (maybe it starts automatically) 2) the part above and the various menus must remain in webview. 3) I have a problem that torments me .. streaming if for example I put the cell in an icon or put the audio block off after a few minutes. I don't understand why it's never a fixed time. 4) I would also like the radio notification when it is running in the upper left corner see attachment. I uploaded 2 screenshoots to let you know how I would like to edit the app. THE MOST IMPORTANT THING IS TO UNDERSTAND WHY AUDIO MUTE AFTER TOT. MINUTES AND OBVIOUSLY FIXING IT.
