title: Android Device is not register into parse installation
body: <p>Right now I am using following code:</p>
  
  <pre><code>Parse.initialize(this, Constant.PARSE_APPLICATIONID,
  Constant.PARSE_CLIENT_KEY);
  ParseInstallation installation = ParseInstallation
                          .getCurrentInstallation();
  
                  installation.put(Constant.TAG_USER_OBJECTID, user.getObjectId());
                  installation.put(Constant.TAG_IS_ENABLED, true);
                  installation.saveInBackground();
  </code></pre>
  
  <p>And also try with following code too.</p>
  
  <pre><code>ParsePush.subscribeInBackground("", new SaveCallback() {
      @Override
      public void done(ParseException e) {
          if (e == null) {
              Log.d("com.parse.push",
              "successfully subscribed to the broadcast channel.");
          } else {
              Log.e("com.parse.push", "failed to subscribe for push", e);
          }    
      }
  });
  </code></pre>
  
  <p>So, that using above code my android device is not register into ParseInstallation class.</p>
