Hello all,

  IN SHORT:
I need to get instance of PowerManagerService (in order to call its method
isScreenBright). However I am unable to do it, after reading Android
sources, the closest guess was to get it (via reflection) from
android.os.ServiceManager by calling getService. The problem is the
resulting class name is BinderProxy (the class name of the object which I
get after actual invoke of getService), not PowerManagerService and I am
stuck at this point. The types have to match in order to continue working
with reflection invoking.

  BACKGROUND STORY (safe to skip it):
I try to read real brightness of the screen (not the one that should be
set, but the real one). All top level brightness readers method return
theoretical values (most likely -- from settings), so when phone lowers it
automatically, those top level methods get the same result despite, the
brightness changed. I figured out, I try isScreenBright method, it should
tell me if phone is in normal brightness mode, or in power save mode
(source code which sets this mode look promising anyway).

Thank you in advance.

Bad news, but thank you. I wonder how it is possible, that (according to
Android sources) what is added to services is PowerManagerService, but what
is get is PowerManager (not service) -- when using "legal" methods such as
getSystemService.

Anyway, quite easy task -- for learning Android -- as building custom
screensaver turned out to be paramount problem :-(

Cheers,

PowerManager is the public API.  Context.getSystemService() returns public
APIs.

PowerManagerService is private implementation.  More than that, it is
private implementation that does not run in your process, so you can not
directly access in any way.
