title: Can we add multiple ViewModel.observer() method in a single activity
body: <p>I have an activity that performs multiple  background tasks, for example: </p>
  
  <p><code>getJWTToken(), sendFCMTokenToServer(), isPromoAvailable(), isForcedUpgradeRequired(), fetchNewsFromServer(), sendUserLatLngToServer()</code></p>
  
  <p>These all are network calls, and take some time. </p>
  
  <p>This is what i have done for 1 method.</p>
  
  <pre><code>HomeViewModel homeViewModel = ViewModelProviders.of(this).get(HomeViewModel.class); 
  
  
      homeViewModel.sendFCMTokenToServer().observe(this, isFCMSendToServer -&gt; {
         Toast.makeText(this, "Home FCM Observer called", Toast.LENGTH_SHORT).show();
       });
  </code></pre>
  
  <p>Now my question is do i need to repeat the above line <code>homeViewModel.observer(this, )</code> for each method, or there is some other way for achieving this.</p>
