Android的MediaPlayer错误

 
阅读更多

在使用MediaPlayer的时候,要注意几个Listener的配合使用,但是,MediaPlayer还是会经常报些奇怪的错误信息。

通常这些错误都是由数据源或者调用MediaPlayer中的方法时没有注意MediaPlayer的状态而引起。

 

常见错误信息分析:

 

(-38,0)

一般是由于在MediaPlayer还没有Prepared的状态下调用了类似getDuration()之类的方法而引起,

例如报错:Attempt to call getDuration without a valid mediaplayer

 

 

 

以下是MediaPlayer的错误类型源码:
