title: How to detect if Google Play is installed? (Not Market)
body: <p>Whether the app installed is called Google Play or Market, the package name is the same <code>com.android.vending</code>.</p>
  
  <p>I need to be able to detect whether the app is Google Play or Market, I've checked in PackageInfo and nothing except <code>versionCode</code> and <code>versionName</code> can be of help.</p>
  
  <p>Does anyone know what the first <code>versionCode</code> was or <code>versionName</code> was for Google Play app?</p>
  
  <p>If anyone knows any other way of detecting this let me know.</p>
