I have found one answer that appears to say I should create a separate class and make a static MyApplication object and make a get method. Then any class can call MyApplication.get() to retrieve the context.

Is there any other cleaner way? This is my situation:

I have a class A and a class B. Class A contains an object from class B (let’s call the object b). In class A I call, “b.play()”. However, I get a null pointer exception because class B needs to pass a context to the MediaPlayer.create() method.

Until now I threw together a hack and from class A I called…. “b.play(this)” and simply passed the context to B. However that is pretty ugly and looks like a bad use of OOP.

Any thoughts?

    If class B requires a Context to operate, then I don’t see any problem having class A provide that to it (through a parameter on the play method, a parameter in a constructor, etc).

    I don’t think you are doing any poor OOP by providing class B the dependencies that it needs to do it’s job.
