MVC Architecture in Android

MVC represents Model-View-Controller

Model:

• Manage the behavior and data of the application
• Responds to requests for information about its state (usually from the view)
• Responds to instructions to change state (usually from the controller)
• Allows the views to produce updated output

View:

• Typically a user interface element
• One to one correspondence with a display surface
• Present the model to the user
• Generates the output representation to the user

Controller:

• Controls both model and view
• Accepts input from the user and instructs the model and the view to perform actions based on that input
• Update view when model changes
• Update model when user manipulate the input
