Though it is old one, but no one has answered it yet. Any hidden classes can be used using reflection APIs. Here is an example to acquire a service using Service Manager via reflection APIs:

if(mService == null) {
            Method method = null;
            try {
                method = Class.forName("android.os.ServiceManager").getMethod("getService", String.class);
                IBinder binder = (IBinder) method.invoke(null, "My_SERVICE_NAME");
                if(binder != null) {
                    mService = IMyService.Stub.asInterface(binder);
                }

                if(mService != null)
                    mIsAcquired = true;

            } catch (NoSuchMethodException e) {
                e.printStackTrace();
            } catch (ClassNotFoundException e) {
                e.printStackTrace();
            } catch (IllegalAccessException e) {
                e.printStackTrace();
            } catch (InvocationTargetException e) {
                e.printStackTrace();
            }

        } else {
            Log.i(TAG, "Service is already acquired");
        }
