Android :: Accessing Inner Variable From Outer Class Method In Android Activity

I m doing some task with following code,
I want to access inner class variable from outer class method.
class Outer extends Activity
{private Handler mHandler = new Handler();
StopTheThread()
{mHandler.removeCallbacks(mUpdateTimeTask);//
This is the what I want to do:
} class Inner
{ final Runnable mUpdateTask = new = new Runnable() {
public void run() {
//Some Code Goes Here
} };
InnerClassMethod()
{ mHandler.removeCallbacks(mUpdateTimeTask);//
This statement working fine here. Here mUpdateTask is inner class variable which is not accessible from outer class.
