难道Android的所有版本支持的MediaPlayer流？ [英] Do all versions of Android support the MediaPlayer streaming?
问题描述
正如标题所说，我基本上想知道，如果在MediaPlayer流支持的作品为Android的所有版本。
As the title says, I'm basically wondering if the MediaPlayer streaming support works for all versions of Android.
下面是我目前使用的code，它在我的Android 2.2手机正常工作：
Here is the code I'm currently using, which works fine on my Android 2.2 phone:
MediaPlayer mp = new MediaPlayer();
mp.setDataSource(SHOUTCAST_STREAM);
mp.prepare();
mp.start();
不过，将这项工作说的1.5或1.6？或者，我将不得不建立自己的缓冲管理体系，为流？
But will that work on say 1.5 or 1.6? Or would I have to build my own buffering management system for the stream?
*更新*
只是测试它的1.6模拟器，并得到以下错误。在2.2模拟器它工作正常。
Just tested it on the 1.6 emulator, and getting the following errors. On the 2.2 emulator it works fine.

那么，这是否意味着它只是简单地不上旧版本的操作系统的工作，或者是有任何变通？我想我可以只是做一个自定义的缓冲系统，但我要确保没有第一更简单的方法。
So does this mean it just simply doesn't work on on the older versions of the OS, or is there any work around? I guess I could just do a custom buffering system, but I want to make sure there isn't an easier way first.
推荐答案
根据 Android的参考在MediaPlayer类，因为API的级别已经可以：1并没有关于它是德precated什么。所以，我要说，你是安全的。
According to Android References the MediaPlayer class has been available since api level: 1 and there isn't anything about it being deprecated. So I would say you would be safe.
在您的1.6模拟器你开始浏览器并确保您可以访问互联网？
On your 1.6 emulator have you started the browser and made sure you can access the internet?
是，你必须创建前一段时间的1.6模拟器吗？我有问题与我有一段时间（的文件遭到损坏）之后创建的仿真器。如果是这样的话，你可以创建一个新的。
Was the 1.6 emulator one that you have create some time ago? I have had issues with emulators that I have created after a period of time (the files get corrupted). If that is the case you could create a new one.
我只是想到......另一件事是有一些认证失踪的地方？
Another thing I just thought of... Is there some authentication missing somewhere?
我发现这个<一个href=\"http://blog.pocketjourney.com/2008/04/04/tutorial-custom-media-streaming-for-androids-mediaplayer/\"相对=nofollow>可能会有所帮助，以及教程。他确实在他的例子创建一个缓存
I found this tutorial that might be helpful as well. He does create a buffer in his example.
