How to use onActivityResult method from other than Activity class

Question

I am creating an app where i need to find current location of user .

So here I would like to do a task like when user returns from that System intent, my task shou

Answer 1

Finally i got what i need and also the solution for this question.

 Activity con;
Intent intent_= new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
            con.startActivityForResult(intent_, 0);

Now i can create a method here,

public void startActivityForResult(Intent i, int code)
{
    Log.e("", "insede method startActivityForResult()");
}

By using this System is not creating a sub-activity for my intent so,this method gets called only after user return from intent.
