IntentService is one of the least difficult approaches to offload "pieces" of handling of the UI string of your application and into a remote work line. There's no compelling reason to dispatch an AsyncTask and oversee it every single time you have all the more handling. Rather, you just characterize your own administration, bundle up expectation with the proper information you need to send for handling, and begin the administration. You can send information back to the application by essentially communicating the outcome as an Intent article, and utilizing a communicate recipient to get the outcome and use it inside the application.

Every one of the solicitations is controlled utilizing a solitary specialist string so they might be in some cases tedious. Be that as it may, they don't meddle with the principle circle of the application.
