title: Can`t add Mandrill`s JARs whithout conflict in Android Studio
body: <p>I want to use in my Android project Madrill`s libraries(I use Gradle). I am tried many times to add secondary libraries(like gson, httpcore..) to the project, but it always conflicted(as far as I understood from searches on the Internet) and I get different errors, mostly like:</p>
  
  <pre><code>Error:Execution failed for task ':app:dexDebug'.
  &gt; com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.7.0_71\bin\java.exe'' finished with non-zero exit value 2
  </code></pre>
  
  <p>or this:</p>

  <p>I used <a href="http://ethicsoftmagazine.com/34/" rel="nofollow noreferrer">this guide</a> and I found the same files, I tried to add JARs a variety of ways, but always I see first error message. (I <a href="https://stackoverflow.com/questions/31817947/java-lang-nosuchmethoderror-when-trying-to-use-madrill-in-android-app">asked</a> a question about it, but perhaps it was necessary to ask it a little differently.)
  So, someone could gather these files into one project that they did not create such mistakes?</p>
