[android-developers] is this a bug in android OS

i am usign a very simple scenario.
i have a remote service created and binded properly.
I can access service methods as described in the aidl interface but
only from the click listener, and can never access using it using
onCreate or other functions.

i have tried 3 different approaches as available on books or net to
consume service. however result is same.

for instance if i create mSercvice as my Service class variable and in
the interface i have method getStatus() which returns boolean.

now after binding service if i call mService.getStatus() from
onClickListener or ServiceConnection Stub, ican access very easily
without a error.
but if i try to get from onCreate (my app fetches parameter status
from service), the value of mService gets null and system exits with
Force Close (due to nullpointexception as from log).

Now can somone please help, as i dont think the value should be null
since the variable is declared globally. so how does the stuff goes..

One of my friend on this group told, if you dont get output all times,
its a bug.

sorry for bad english...
