title: Creating a zip file with some files on SDCard
body: <p>As I posted a question a few days ago, I realized thet the stock eMail app couldn't send multiple files in attachment: <a href="https://stackoverflow.com/questions/5773006/sending-email-with-multiple-attachement-fail-with-default-email-android-app-but">https://stackoverflow.com/questions/5773006/sending-email-with-multiple-attachement-fail-with-default-email-android-app-but</a></p>
  
  <p>Unfortunately, I got no answer on it, so need to find a workaround.</p>
  
  <p>The user has to select in a list some pdf and send them by email with stock app. As the multiple attachment fail, I will create a zip file with all the requested files and sent this unique file.</p>
  
  <p>So, hoz can I make an archive with some files on SDCard?</p>
  
  <p>What I currently found is this: <a href="http://developer.android.com/reference/java/util/zip/ZipFile.html" rel="nofollow noreferrer">http://developer.android.com/reference/java/util/zip/ZipFile.html</a></p>
  
  <blockquote>
    <p>public ZipFile (File file)</p>
    
    <p>Since: API Level 1 Constructs a new
    ZipFile with the specified file.</p>
  </blockquote>
  
  <p>But I don't understand how to use this with multiple files.</p>
  
  <p>Thank a lot, </p>
