Android Application Components Activities, Services, Broadcast Recievers, Content Providers - ABNHive

Application components are the essential building blocks of Android app development.  Each component is an entry point through which the system or a user can enter your app. There are 4 types of components in android Activities Services Broadcast receivers Content providers Let's dive into the deep.  Activities This is a component that represents a single screen with a user interface or simply an entry point for interacting with the user. Example, an email app might have one activity that shows a list of new emails. Activities work together to form a cohesive user experience in the app. For example, clicking a button on the first screen might replace that screen with another screen containing other widgets, a web page, a movie, or text information. Activities are typically created by subclassing (extending) the Android class Activity.  click here   to know more about Activity.

Services in Android - ABNHive

A service is a component which runs in the background without direct interaction with the user.  A service extends the base class Service . Services run with a higher priority than inactive or invisible activities and therefore it is less likely that the Android system terminates them for resource management. The only reason Android will stop a Service prematurely is to provide additional resources for a foreground component usually an Activity. When this happens, your Service can be configured to restart automatically. You can start a service if it is not running using Context.startService(), connect (bind) to a running service using Context.bindService(), and communicate with the running service through an interface that the service exposes. Each service class must have a corresponding <service> declaration in the AndroidManifest.xml file for its package. Types of Services Bound Service Service which call indefinitely in between activity. An Android component m...
