title: Firebase Remote Config fetch doesn't update values from the Cloud
body: <p>I'm trying to set up Firebase Remote Config for my project.
  I added Firebase via the Assistant. I added values to the server values on Google Cloud Console:</p>
  
  <p><img src="https://i.stack.imgur.com/4aOnO.png" alt="1"></p>
  
  <p>I've created default values xml in res/xml</p>
  
  <pre><code>&lt;defaultsMap&gt;
  
  &lt;!-- Strings--&gt;
  &lt;entry &gt;
      &lt;key&gt;textView_send_text&lt;/key&gt;
      &lt;value &gt;your phrase goes here.&lt;/value&gt;
  &lt;/entry&gt;
  
  &lt;/defaultsMap&gt;
  </code></pre>
  
  <p>Thats my MainActivity:</p>
  
  <pre><code>final private FirebaseRemoteConfig mFirebaseRemoteConfig = FirebaseRemoteConfig.getInstance();
  
  protected void onCreate(Bundle savedInstanceState) {
      //..code..
  
      //fetch from Firebase
      fetchAll();
  }
  
  private void fetchAll(){
       final FirebaseRemoteConfig mFirebaseRemoteConfig = FirebaseRemoteConfig.getInstance();
  
      FirebaseRemoteConfigSettings configSettings = new FirebaseRemoteConfigSettings.Builder()
              .setDeveloperModeEnabled(BuildConfig.DEBUG)
              .build();
      mFirebaseRemoteConfig.setConfigSettings(configSettings);
  
      mFirebaseRemoteConfig.setDefaults(R.xml.defaults);
  
      mFirebaseRemoteConfig.fetch()
              .addOnCompleteListener(this, new OnCompleteListener&lt;Void&gt;() {
                  @Override
                  public void onComplete(@NonNull Task&lt;Void&gt; task) {
                      if(task.isSuccessful()){
                          Toast.makeText(MainActivity.this, "Fetch Succeeded",
                                  Toast.LENGTH_SHORT).show();
  
                          mFirebaseRemoteConfig.activateFetched();
                      }else{
                          Toast.makeText(MainActivity.this, "Fetch Failed",
                                  Toast.LENGTH_SHORT).show();
                      }
  
                      displayWelcomeMessage();
  
                  }
              });
  
  
  
  
  
  }
  
  private void displayWelcomeMessage(){
      String welcomeMessage = mFirebaseRemoteConfig.getString("textView_send_text");
  
      Toast.makeText(this, welcomeMessage,
              Toast.LENGTH_SHORT).show();
  }
  </code></pre>
  
  <p>Toast output:</p>
  
  <p><img src="https://i.stack.imgur.com/twJVm.png" alt="2"></p>
  
  <p>So Toast gets the value from xml/defaults not from the Cloud.
  It'd be much appreciated if somebody found where I made a mistake.</p>
