From 053b9c7a4b2662588706211fd8aa1f8a03ec2901 Mon Sep 17 00:00:00 2001 From: Andrew Lee Date: Thu, 18 Jun 2015 18:19:20 -0700 Subject: Rewrite of MediaPlayer logic. + Control MediaPlayer instance more tightly. Wait until prepareContent to initialize instance. Release MediaPlayer when it is no longer needed. + Instead of using isFinishing, check explicitly for orientation change to know whether to release MediaPlayer. + Change Presenter to singleton, to address audio change wonkiness. + Only create a Presenter if the call log fragment shows voicemail. + ... fixing a variety of cases. - Temporarily disable proximity sensor until blocking issue is fixed.
