Multiple plugins with the same name
<p>I have difficulty finding answer of these errors. </p>

<p>Before seeing these errors, I did it as follows :</p>

<p>1) I did delete Oculus package (for Unity 4)</p>

<p>2) I did import Oculus Package (for Unity 5)</p>

<p>3) Built my unity project for Android OS, but these errors occurred</p>

<blockquote>
  <p>Multiple plugins with the same name 'leap' (found at
  'Assets/Plugins/Leap.dll' and 'Assets/Plugins/x86_64/Leap.dll'). That
  means one or more plugins are set to be compatible with Editor. Only
  one plugin at the time can be used by Editor.

<p>There are Leap.dll &amp; LeapCSharp.dll file in both 'Plugins' and 'x86_64' folder.</p>

<p>How to solve these problem? Can you help me? Thanks in advance!</p>

<p>+) My Unity version is 5.3.5f Pro version.</p>
