title: how to update Google Play service on Emulator android studio
body: <p>I got the Key and set restrict, but I still cannot open map on the Emulator. On the build.gradle, I saw that the google play service is 9.8.0 now, and I think this is the newest one. However, when I run the sample-app, it say I need to update Google Play service?</p>
  
  <pre><code>dependencies {
  compile fileTree(dir: 'libs', include: ['*.jar'])
  testCompile 'junit:junit:4.12'
  compile 'com.android.support:appcompat-v7:23.4.0'
  compile 'com.google.android.gms:play-services-maps:9.+'
  </code></pre>
  
  <p>}</p>
  
  <p>I check on the Android Emulator that it doesn't have Play store. Is it the missing one? I follow this link
