title: How to make a beep in android?
body: <p>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</p>
  
  <pre><code>beep(frequency, duration); 
  </code></pre>
  
  <p>Is this the same in android? Or at least how can I put my c++ dll in the project?</p>
  
  <p>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.</p>
