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.
Thanks,
Mitul
