title: java.lang.ClassNotFoundException: Didn't find class "com.google.android.maps.MapView"
body: <p>I am trying to add Map functionality to my app. My IDE is <code>AndroidStudio</code>. I've gone to the SDK Manager and installed both <code>Google Play services</code> and <code>Google repository</code>.</p>
  
  <p>Then, in my gradle file, I've added <code>google play services</code>:</p>
  
  <pre><code>dependencies {
      compile 'com.android.support:appcompat-v7:+'
      compile 'com.android.support:support-v4:19.1.+'
      compile 'com.google.android.gms:play-services:4.3.23'
      compile fileTree(dir: 'libs', include: ['*.jar'])
  }
  </code></pre>
  
  <p>After this, I've synced the project with the gradle files.</p>
  
  <p>In my fragment, I've added <code>MapView</code> (and my API key). No error during compile, however, I get this during runtime:</p>
  
  <pre><code>Caused by: java.lang.ClassNotFoundException: Didn't find class "com.google.android.maps.MapView" on path: DexPathList[[zip file "/data/app/com.app.app-1.apk"],nativeLibraryDirectories=[/data/app-lib/com.blueforcemedia.blueforcetracker-1, /vendor/lib, /system/lib]]
              at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:56)
      }
  </code></pre>
  
  <p>What am I doing wrong?</p>
