app.config(['$routeProvider', function($routeProvider) {
  $routeProvider
    .when('/home', {
      templateUrl: 'views/home.html',
      controller: 'HomeController'
    })
    .when('/profile', {
      templateUrl: 'views/profile.html',
      controller: 'ProfileController'
    })
    .when('/friends', {
      templateUrl: 'views/friends.html',
      controller: 'FriendsController'
    })
    .when('/messages', {
      templateUrl: 'views/messages.html',
      controller: 'MessagesController'
    })
    .otherwise({
      redirectTo: '/home'
    });
}]);

app.controller('MainController', ['$scope', function($scope) {
  // MainController logic here
}]);

app.controller('HomeController', ['$scope', function($scope) {
  // HomeController logic here
}]);

app.controller('ProfileController', ['$scope', function($scope) {
  // ProfileController logic here
}]);

app.controller('FriendsController', ['$scope', function($scope) {
  // FriendsController logic here
}]);

app.controller('MessagesController', ['$scope', function($scope) {
  // MessagesController logic here
}]);
```

Please note that the controller logic for each controller is currently empty. You can add your specific logic and functionalities within each controller based on your requirements.

Also, make sure to create the corresponding view files (`home.html`, `profile.html`, `friends.html`, `messages.html`) in a views folder and link them appropriately in the route configuration.
