From 32e36b84e103862364a8a037272156b2b3814b6f Mon Sep 17 00:00:00 2001 From: Kevin Tang Date: Thu, 15 Aug 2019 15:43:03 -0700 Subject: delete of shared LocApiBase::mMsgTask may cause issues mMsgTask is static, its delete would impact other LocApi objects which don't know it is deleted. Added refcount to manage this shared obj.
