Sample text

In this case, the Service runs in the background and the application components bind to the Service by calling bindService (). Such a Service is called a bound service. A started service extends either the Service class or the IntentService class. The main difference between the two approaches is the handling of multiple requests. When extending the Service class, the application needs to take care of handling multiple requests. This is done in the onStartCommand() method. The IntentService() class makes it easier by queuing all the requests and processing them one at a time, so the developer does not need to take care of threading.

And imagine the scenario where the Intent is not only sniffed but also altered by the malicious application. [ 13 ] Android Security Model – the Big Picture As an example, the following figure shows two applications, Application A and Application B, both with their own stack of components. These components can communicate with each other as long as they have permissions to do so. An Activity component in Application A can start an Activity component in Application B using startActivity() and it can also start its own Service using startService().

START_REDELIVER_INTENT: In this option, the Service is restarted and the pending Intent is redelivered to the Service onStartCommand(). An example is downloading a file over the network. It is important to note that a Service is different from creating a thread. A thread is killed immediately when the component that spun it is killed. A Service by default runs in the global application thread and remains alive even if the invoking component is destroyed. If the Service is doing some time consuming activity such as downloading a huge file, it is prudent to do it in a separate thread to avoid blocking the application.
