Model View Controller (MVC), Model View Presenter (MVP) and Model View View-model (MVVM) are the models briefly discussed and the impact or implementation in Android App Development Services in Saudi Arabia.  They are used to reduce the complexity of the Appsout and make it intelligible. To clarify all the discussion takes place in the context of Appsout in Android App Development Services in Saudi Arabia as a platform. The MVP, MVC and MVVM patterns are discussed below:

·         MVC (Model View Controller)

Model View Controller consists of three main components, around which the entire development process revolve are mentioned below:

       View

 This component interacts directly with the user and is responsible for how the user will see Android App Development Services in Saudi Arabia. In MVC, Xml is treated as a view.

    Model

 The model is the data source for the application and the main business logic is defined here, it contains data objects that are used in the Android App Development Services in Saudi Arabia and are shown to the user. The data source can be web, local database (sqlite), etc.

      Controller

 The most important part of the MVC pattern, the controller is the component that manipulates, edits, uses the data model and shows it to the users through the view. The controller is responsible for collecting all the data and acting as intermediaries between the model and the view. Activity / Fragments are considered controllers in Android App Development Services in Saudi Arabia.

The activity / Fragment can be used to draw multiple views for a single screen in the application, therefore, all the different data calls and views are filled in the same place. Therefore, to solve this problem, we can use a different design pattern or we can implement MVC carefully, taking into account the conventions and following the appropriate programming guidelines.

·         MVP (Model View Presenter)

Model View Presenter (MVP) is derived from the MVC pattern. It is emerging and becoming popular among developers. MVP can somehow minimize View's high dependency by separating the display layer of the business logic layer by presentation layer. The presentation layer decides what to show in the view. It allows you to discuss your component individually in Android App Development Services in Saudi Arabia.

         View

 Displays information to users and contains the UI component. XML file, Activity, fragments, Dialog appears below Layer of view. No other logic has been implemented.

   Model

 The model here also plays the role of domain or business layer and is a source of pattern data. Describe the main logic of the Android App Development Services in Saudi Arabia and decide from where the data should be obtained.

   Presenter

 This layer performs the functionality of the controller and acts as an intermediate layer between the view and the model layer. But unlike the driver, it does not depend much on View. See the contact presenter for the data that will be presented, then the presenter takes the model data and returns to see it in presentable format. Presenter is a simple Java class that does not contain any user interface components, it simply manipulates the model's data and displays them in the view of Android App Development services in Saudi Arabia.

It depends entirely on mobile architects and the approach to a problem that decides how we can implement this pattern, there are many ways in which this pattern can be implemented in Android App Development Services in Saudi Arabia, but the main idea of ​​freely coupling the view / model interaction must be preserved.

The presenter communicates with the view through the interface. The interface is defined in the presenter class, to which it passes the required data. The activity / snippet or any other view component implements this interface and processes the data in the way you want.

·         MVVM (Model-View-Model-Model)

Model View View-Model was introduced in Google I / O last year. This architectural plan is becoming popular due to the features it provides. Mainly implements the Data Link Framework, allows the "linking" of views to fields in an arbitrary object the architecture introduces bidirectional communication between its components. Along with functions like the link, the current. It is completely independent of Views of the consumers of Android App Development Services in Saudi Arabia.
