title: How to convert .jar or .class to .dex file?
body: <p>I'm going to edit the Opera Mini v6.5 server because it is blocked in our country.</p>
  <p>Now I have unpacked the ‍‍‍‍‍‍‍<code>.apk</code> file extracted <code>classes.Dex</code> then converted it via <code>dex2jar.bat</code>, now modified the server.</p>
  <p>My problem is I want to repack the <code>.jar</code> or <code>.class</code> to <code>classes.Dex</code>. How do I do it?</p>
