Q:

Explain how synchronization takes place with Blackberry Technology .

Answer

The handheld device is used as a network device, which always connected to the data account of the user via redirector software. The software is installed on the BlackBerry Enterprise Server. The communication between the software, BE Server and the hand held device’s software is always a two-way street. BES immediately updates the mobile device or the email or the calendar account, whenever a change in email account occurs.

The push technology of BlackBerry keeps the device instantly in “synch” without any effort by the user.

Q:

What is the procedure to check status of an activity in Android?

Answer

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.
