title: How to get GSF (Google Service Framework) ID from adb?
body: <p>I found out it could be done in java through </p>
  
  <pre><code>Uri URI = Uri.parse("content://com.google.android.gsf.gservices"); 
  </code></pre>
  
  <p>and many app on play store could do that. However, is there anyway the gsf id can be obtained through adb?</p>
  
  <p>I tried:</p>
  
  <pre><code>content query --uri content://settings/secure/android_id #to get the android id
  content query --uri content://settings/secure/ #to see the list of dictionaries but gsf id not in there
  content query --uri content://com.google.android.gsf.gservice #doesn't return a value, and this should be where the java code in the app get the value from, already granted superuser for the shell.
