Q:

What is the main reason of using process lifecycle in Android?

Answer

The android system will keep all the process that are hosting the services together at one place till the time the service is not started or connected to the client. The priority of the process is divided when running low on memory or when the process has to be killed. The process lifecycle is as follows:
- The service is running currently then the methods onCreate(), onStartCommand(), and onDestroy()methods, will run in the foreground to execute the process without being killed.
- The service is already started then the process can be considered as less important then the processes that are currently visible and used. This is done as there are only few processes that are visible to the users on the screen.
- The clients are bounded to the services they are providing requires more priority in the execution list.
- The service that is started uses startForeground(int, Notification)API to allow all the services to run in the foreground state. The system considers only the services where the user is still active as the services not to be killed.

Q:

What would be the most important service skill that you would need to have in your day to day business?

Answer



1.Patience:If you deal with clients on a daily basis, be certain to stay patient when they come to you confused and frustrated, but also be clear to take the time to truly find out what they need — they'd rather get good service than be rushed out the door!


2. Attentiveness: The capacity to surely listen to customers is so crucial for presenting extremely good service for a number of reasons.


3.Communication Skills: When it comes to crucial points that you want to relay clearly to customers, keep it easy and leave not anything to doubt.


4.Knowledge of the Product: Not knowing your product from front-to-back, you might not know how to solve customer issues when they run into problems.


5.Willingness to Learn: Those who don't show to enhance skills what they do, whether it's helping customers, marketing businesses, or building products, will get left behind by the people willing to put money into their skills.


6.Ability to Use "Positive Language":


    Without positive language: "I cannot get you that product until next month; it is back-ordered and unavailable presently."


    With positive language: "That brand will be available coming month. I can place the order for you immediately and make sure that it is posted to you as soon as it reaches our war
