Android's implementation of vibrator needs to be done inside a hardware module, so that it can make a vendor implementation possible. Hw module's name becomes vibrator.default.so. This change is related to other changes in: - frameworks/base - hardware/libhardware_legacy - device/generic/goldfish - platform/build Change-Id: I844279f5535289f079d412fdc44c5cb3c9c1130c Author: Vincent Becker <vincentx.becker@intel.com> Signed-off-by: Vincent Becker <vincentx.becker@intel.com> Signed-off-by: Shuo Gao <shuo.gao@intel.com> Signed-off-by: Bruce Beare <bruce.j.beare@intel.com> Signed-off-by: Jack Ren <jack.ren@intel.com> Signed-off-by: David Wagner <david.wagner@intel.com> Author-tracking-BZ: 49760 94611
