  <p>I've looked at past similar questions but was unable to find a solution. I think it has to do with my gradle files, as I just added some Google API stuff. </p>
  
  <p>build.gradle for project:</p>
  
  <pre><code>// Top-level build file where you can add configuration options common to all sub-projects/modules.
  
  buildscript {
      repositories {
          jcenter()
          mavenCentral()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:1.2.3'
          classpath 'com.google.gms:google-services:1.3.0-beta1'
  
          // NOTE: Do not place your application dependencies here; they belong
          // in the individual module build.gradle files
      }
  }
  
  allprojects {
      repositories {
          jcenter()
      }
  }
  </code></pre>
  
  <p>build.gradle for module:</p>
  
  <pre><code>apply plugin: 'com.android.application'
  apply plugin: 'com.google.gms.google-services'
  
  android {
      compileSdkVersion 22
      buildToolsVersion '22.0.1'

  <p>The only stuff that has been added to those files since my last successful debug is the Google stuff. I tried clean build, delete .gradle, and delete .idea. </p>
  
  <p>EDIT:
  Here are the jars in my libs folder, in case some are conflicting:
  gdata-client-1.0.jar <br>
  gdata-client-meta-1.0.jar<br>
  gdata-core-1.0.jar<br>
  gdata-spreadsheet-3.0.jar<br>
  gdata-spreadsheet-meta-3.0.jar<br>
  google-play-services.jar<br>
  gson-2.2.4.jar<br>
  guava-18.0.jar</p>
  
  <p>EDIT 2:
  After following the instructions in the comments below the error message changed to this:</p>
  
  <pre><code>Execution failed for task ':app:packageAllDebugClassesForMultiDex'.
  &gt; java.util.zip.ZipException: duplicate entry: com/google/android/gms/internal/x.class
  </code></pre>
  
  <p>I went through my libs but was only able to find the gms directory in the google play jar so I don't know what it's conflicting with.</p>
