direct Global viable access using an "Application" class?

i want to setup a global variable class holder extending "Application" like this one here:

my question is it possible to access the viable directly instead of calling a method?

(going by the link's example) can "islogin" be declared as:

public boolean isLogin = true;

then accessed like this?:

if (!combankDroid.isLogin) {

You can do what you want: global variables on Application objects work just fine.

The actual solution to your issue is to make the MediaPlayer instance a variable of a Service and then connect to that to fetch/control the MediaPlayer.
