关于player的一些东西

//**************************************Player的销毁

        if(playerSound != null){
            playerSound.deallocate();
            playerSound.close();
            playerSound  = null;
        } 

一定要加deallocate();，否则就算 =null 内存也没减少

//*******************************************************************

            player = Manager.createPlayer(getClass().getResourceAsStream("/sound/" + path + ".mid"), audio/midi");//
            player.setLoopCount(type); //播放次数，-1为循环
            player.realize();
            player.prefetch();
            player.setMediaTime(0);//从时间为0开始拨，

手机有些方法不一定支持，要试试看
