For launching an application, we will need to create an intent that explicitly defines the activity that we wish to start. For example:

Code

        Intent intent = new Intent(this, MyTestActivity.class);

        startActivity(intent);

The status of an activity can be start and stop only. The start means the activity is up and running. It is in execution state and performing some actions. Whereas the stop state defines that the activity is being stopped and performing no action on the system. To see or check the status of an activity there is a command that has to be used like NEW_TASK_LAUNCH flag that keeps the track of all the activities that are running and the main command under which the flag resides is given as startActivity() call. To bring the activity stack in front of the process that is already running require the command mentioned above to be used. The activity can be started remotely by using the remote services. These services allow easy interaction with the client and provide the sample to show it on the local server.
