Why we declare the member variables before the on create method? I don't see the reason for this.

Can someone explain?

When we create the mVariables before the On create method, where are they created? Shouldn't I create another activity (as it was done in the Fun Facts project) so that variables refer to other activity.

Thanks and sorry for the noob question! ;)

It is a matter of scope. If we declare a variable from within a method, the variable can only be accessed within that method. When we declare the variable in a class but outside a method, the variable can be used anywhere within the class and is not dependent on any given method.
