Playing A Video File On Button Click

Whenever I'll put this codes line into the button onClick event then it will gave me error ho to resolve it. The Error on a line of 'mc = new MediaController(this); ' and error is

Solution 1:

mc = new MediaController(this);

on this line you are passing Context of Button click, I think you should pass here your Activity Context. For this you should declare a Context

Private Context context; inside Class and then inside onCreat() you shiuld initialize it by

context = this;

and use

mc = new MediaController(context);      // this is using context of Activity Class. 

this is better way to resolve Context problem.
