 setDataSource called in state 8

查了查资料和网上的解决办法如下: 
mp.setDataSource(PATH_TO_FILE); 
    mp.prepare(); 
这个地方修改如下： 
File file = new File(strPath); 
FileInputStream fis = new FileInputStream(file); 
mediaPlayer.setDataSource(fis.getFD()); 
mp.prepare(); 
或者 
把mediaPlayer.prepare;改成 
mediaPlayer.prepareAsync(); 
这种情况会报个prepare called in state 8错误 ，后面的方法不好使，最好是用前者
