From b731ae01b15682a3326dc4145f614f919b2789b5 Mon Sep 17 00:00:00 2001 From: Colin Cross Date: Wed, 28 Mar 2012 13:55:43 -0700 Subject: Move services/powermanager from frameworks/base to frameworks/native Move services/powermanager into frameworks/native so audioflinger can use it. Note that this is not the same as a PowerManagerService, which is part of systemserver and handles turning the screen on and off, etc. This is just a binder interface to allow taking wakelocks.
