title: What is the build.gardle file how can I configure this file?
body: <p>I'm trying to add ACRA library into my android project, using eclipse.
  I have to add dependency in Build.gardle,
  like this:</p>
  
  <pre><code>dependencies {
      compile 'ch.acra:acra:4.6.2'
  }
  </code></pre>
  
  <p>I don't understand how to change my project to using this gardle file,
  and how to configure this file.</p>
