Hi, In my program I have one class which looks like this public class A extends B{ ............}
Here Class A is my application class and it Extends Class B. Class B is not an Activity class provided by Android. And class B has extended View. Now the problem is beacuase of this structure I am not able to do certain asctivities like Playing Music, creating new intent as for that I have to extend Activity class in Class A. So I don't how I can do that. I have implemented one solution to play music . I created other class file which has code to play music and I have created object of it in Class A. But it is also not working. The code in class which implmented looks like this. public class c extends Activty { public void mediaplay() { try { MediaPlayer menusound = MediaPlayer.create (C.this ,R.raw.eat); menusound.start(); } catch (Exception e) { Log.e("Sound", "error: " + e.getMessage(), e); } } } and i m creating its object in class A using this: C o = new C(); and I use this o object in class A like this: 0.mediaplay(); But when it is called in C, MediaPlayer.create thorws null pointer exception. So how can I solve this? It will solve some of my problems.
