  <p>My build.gradle is like</p>
  
  <pre><code>dependencies {
      compile fileTree(dir: 'libs', include: ['*.jar'])
      compile 'com.android.support:appcompat-v7:21.+'
      compile 'com.google.android.gms:play-services-location:6.5.+'
      compile 'io.nlopez.smartlocation:library:2.0.7'
  }
  </code></pre>
  
  <p>I have been searching around SO here and google but still can't solve it. it was saying that the attribute "theme" is conflicting between play service and appcompat. I try to change to </p>
  
  <pre><code>compile 'com.android.support:appcompat-v7:21.0.0'
  </code></pre>
  
  <p>but still the same.</p>
  
  <p>My gradle version is</p>
  
  <pre><code>classpath 'com.android.tools.build:gradle:0.13.2'
  </code></pre>
  
  <p>Appreciate any help please. Thanks !</p>
  
  <p>regards,
