title: Cannot resolve symbol 'LocationRequest' Android project
body: <p>I'm new on Android programming, I try to use the new Location Service for getting the user position, to do this i follow the official android developer guide but I don't understand why I'm not able to import LocationRequest in my fragment class. </p>
  
  <pre><code>import com.google.android.gms.location.LocationRequest; 
  </code></pre>
  
  <p>here is my Gradle app file:</p>
  
  <blockquote>
    <p>build.gradle</p>
  </blockquote>
  
  <pre><code> ..
     compile 'com.android.support:appcompat-v7:24.2.1'
     compile 'com.android.support:design:24.2.1'
     compile 'com.android.support:palette-v7:24.2.1'
     compile 'com.android.support:cardview-v7:24.2.1'
     compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha9'
     compile 'com.google.code.gson:gson:2.6.2'
     compile 'com.android.volley:volley:1.0.0'
     compile 'com.android.support:support-v4:24.2.1'
     compile 'com.google.android.gms:play-services-maps:9.8.0'
   }
  </code></pre>
  
  <p>and this is what I include in my Manifest file</p>
  
  <blockquote>
    <p>AndroidManifest.xml</p>
  </blockquote>
  
  <pre><code>...
  &lt;uses-permission android:name="android.permission.INTERNET" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /&gt;
  ...
  </code></pre>
