Merge tag 'android-4.4.1_r1' into somex-4.4

Android 4.4.1 Release 1

Fixed the Music app crash issue when the repeat button is disabled.

When the music application is set to REPEAT_NONE mode, the mNextMediaPlayer
didn't set to null. Therefore, the music would play next song, but the index
is invaild and causes the app crash.

Music: Music Force Close when the last song is end and repeat is closed.

getCursorForId(mPlayList[mPlayPos]) will cause ArrayIndexOutOfBoundsException
so need to check the index of mPlayList before use it.
