I'm new to Android development and trying to make a ShoutCast radio app. So far the progress was good until I saw a ViewPager tutorial and now I'm stuck with it. Here is the question:
In first fragment I want my radio stream plays. I can get the stream now but it is in an activity class so I can't do the same thing in my fragment. And in my second fragment I want another activity to run etc.
http://www.youtube.com/watch?v=C6_1KznO95A this is the tutorial I'm trying to implement (if you want I can put the code and the library here.) And here is the code I get the stream and the other things:
PS: I can write your name in the special thanks part of the app if you help me with this problem :)
