It can also process several requests, although one at a time. Offloading the work from the main UI thread into a work queue becomes incredibly easy and efficient using IntentService. IntentServices in Android, although not a well-known Android service, has many applications.

The service stops automatically when all the tasks are completed, eliminating the need to make a call to stop the service.An IntentService is executed on a separate worker thread.A broadcast receiver catches the result for use within an app. Data is easily sent back to an application by broadcasting the result in the form of an Intent object.IntentService allows the simplest ways of offloading “chunks” of processing from the UI thread of the application to a remote work queue without launching an AsyncTask every time processing is required.

Take care of asynchronous requests on the expression of Intent.

The uses of IntentServices in Android are. This service can be employed extending the IntentService with onHandleIntent(Intent). The IntentService class simplifies the pattern and handle the mechanics. To offload tasks from the main thread of an application, the "work queue processor" pattern is employed. However, they do not interfere with the main loop of the application. All the requests are controlled using a single worker thread so they may be sometimes time-consuming. It handles each Intent one by one with the help of a worker thread and stops automatically when the work is done. The requests are sent by the clients through Context.startService(Intent) calls to start the service. IntentService in Android is a base class for Services to handle asynchronous requests that are expressed in the form of Intents when there is a demand to do so. They propose a client-server interface to allow interactions between the components and the service, send requests, obtain results, and interprocess communications (IPC).

Bound- A service is bound when it activates with the call bindService().

Started- A service is started using the call startService() and it indefinitely operates in the background, even if the component starting it is destroyed.

They have no need to interact with a user and have the ability to operate even when an application is destroyed. What is Service in Android?Ī service in Android is a module that can runs in the background in order to perform lengthy operations. It enables an integrated approach to application development for mobile devices and thereby ease the job of the developers who can only develop their applications for Android. the Open Handset Alliance developed Android under the leadership of Google as well as other organisations. It is widely used in mobile devices that include smartphones and tablet computers.

Android is an open source operating system that is based on the programming language Linux.
