Editor's Notes
- An Activity is an application component that provides a screen with which users can interact. Each activity is given a window to draw its user interface. The window typically fills the screen, but may be smaller than the screen and float on top of other windows. An application can have multiple Activities that are linked to one another. They communicate Via Intent. Main activity is the one presented to the user on launching the application. Each Activity can start another Activity. When a new activity starts the old one is stopped and preserved on the Back Stack and the new activity is on top of the stack and takes User Focus. If a User presses the Back button , the current activity is stopped and Destroyed and the previous Activity takes User Focus. Example: In a game , the splash screen , the instruction screen, the main menu screen. Class Used : Activity
- Services do not have any visual UI. Services are Background Processing Components. Services handle the processing that happens in the background, while the user interacts with the UI. Example: In a game, the processing of the game logic is done by Services. In a music player application, we can continue playing the music file while scrolling through the playlist. The music player service keeps running in the background allowing us to view the playlist . Class Used: Service
- Communication Components that receive messages that are sent between the Android OS & other application components, or between Android applications themselves. Android OS sends out messages regarding the status of the device. Example: Low-Battery Warning , Time-Zone change etc. Application to Application Broadcast message are like a “Download complete” notification. Broadcast Receivers Operate in the background has no UI, however, they can invoke a UI activity Based on the messages they carry. Classes used : NotificationManager , BroadcastReceiver
- Provide a way to make data available to an application. The data can be one that is created in and for the same application, or it can be data that is used By an application but created by a different application . It is very flexible to use. Example: An android Phone utility uses a content provider to access phone number database Within the smart-phone. ContentResolver Object is used to talk to any content provider to navigate the data needed. Class Used: ContentProvider
- View Components such as Buttons, Radio Button, Progress Bar etc. Defined in View Class(as a foundation), Sub classed as widgets and contained in a Package called android.widget . ViewGroup Defines the Layouts such Linear, Relative and Sliding Drawers Defined in ViewGroup Class.
- Events System-Generated messages sent to the View object, when a UI element is accessed (touch , click , slide etc.) Event Handling If events are triggered, they are Handled. Event handling is done by methods such as onClick() , onKeyDown() Each View Object will have its own its own unique events , and event handling methods. Listeners Java Interfaces in the View Class that contains a single method to handle a type of UI event. When an event listener interface is implemented , it means that the View class will handle that specific event on that specific View. View.OnClickListener , View.OnLongClickListener etc.
