我正在开发的媒体播放器，并从服务器我的应用程序下载MP3文件。

所以我想从另外一个媒体播放器prevent它来播放它。

案例

用户获取文件从服务器（音乐file1.mp3）的android手机！用户发挥它在我们的球员却无法分享或下载电脑或播放在其他媒体播放器。

我尝试以下

我可以加密文件，并在我的应用程序再次解密（将需要很长一段时间，这是一个移动CPU！），但后来我的应用程序需要有解密密钥内。基本上，任何人都可以阅读我的​​应用程序，所以它不是很好的解决了这个关键的。

所以，请建议我什么，我有什么关系？

谢谢..

写一些其他的应用程序。

你所描述什么是 DRM 。没有已知的DRM系统是牢不可破的。有DRM系统已被打破，并有DRM系统，没有人打扰试图突破呢。

I am developing media player and my application download mp3 file from server .

So i want to prevent it from another media player to play it.

Case

User get file from server (music file1.mp3) in android phone ! User play it in our player but can't share it or download it in computer or play in another media player.

I try Below

I can encrypt a file and decrypt it again in my app (will take long time, it's a mobile cpu!), but then my application needs to have the decryption key inside. Basically anyone can read this key from my app so its not the good solution.

So please suggest me what i have to do ?

Thanks..

Write some other app.

What you are describing is DRM. There is no known DRM system that is unbreakable. There are DRM systems that have been broken, and there are DRM systems that nobody has bothered trying to break yet.
