如何在Android的蜂鸣声？ [英] How to make a beep in android?

问题描述

我想我有一个特定的频率和持续时间的应用程序的响声。在windows相当于这个应用程序（用C＃）我用C ++ DLL的功能

I would like my app beep with a specific frequency and duration. In the windows equivalent of this app (written in c#) I used a c++ dll with the function

beep(frequency, duration); 

这是android系统中的一样吗？或者至少，我怎样才能把我的C ++ DLL项目？

Is this the same in android? Or at least how can I put my c++ dll in the project?

我想preFER不使用pre-内置的MP3或系统的声音，因为我想给用户的频率和持续时间的选择。

I would prefer not to use pre-built mp3's or system sound because I would like to give the user the choice of the frequency and duration.
