The lock screen was using Ringtone for the lock/unlock sounds, which meant two new MediaPlayers were created every time a sound needed to be played. In addition, the Ringtone was assigned to a local variable, which means it could go be garbage collected and finalized while it was still playing. For short sounds that need to be played repeatedly, SoundPool is a better option anyway, so use that instead. b/5382634 Change-Id: I8794cbb24604fa7c03032bd5e32ceab37a858054
