Music: Play fail after tap recent key
1. Play button is fail after tap recent key in AudioPreview
Tapping recent key will invoke onUserLeaveHint and onKeyDown,
we set MediaPlayer as null in onUserLeaveHint and makes
onKeyDown return directly but not invoke finish
2. on Artist screen, clicking Artist group item will not expand
children item in some cases.
The Fragment is cached and makes its isExpand flag keep old value
