I hope this code helps.

  var isLoadingShown = false;

  $scope.$watch(function() {
    return $http.pendingRequests.length;
  }, 
  function(newValue, oldValue) {
    console.log(newValue);
    if(newValue !== 0) {
      if(!isLoadingShown) {
        showLoading();         
      }
    }
    else hideLoading();
  });

  function showLoading(){
    isLoadingShown = true;   
    $mdDialog.show({
      template: '' +
                  '
' +
                    '' +
                  '
' +
                '',
      parent: angular.element(document.body),
      clickOutsideToClose:false,
      escapeToClose: false,
      fullscreen: false
    });
  }

  function hideLoading(){
    $mdDialog.cancel();
    isLoadingShown = false; 
  }
