You can create diverse applications with a variety of features, and design versatile applications and intriguing user interfaces with text and graphics while taking advantage of many device functionalities, such as sensors and call operations. In addition, you can, for example, manage content and media files, use network and social services, and provide messaging and embedded Web browsing functionality.</p></li>

<li><a href="service_app_n.htm">Service Applications</a>
<p>The service application is a Tizen native application without a graphical user interface that runs in the background. They can be very useful in performing activities (such as getting sensor data in the background) that need to run periodically or continuously, but do not require any user intervention.</p></li>
<p>When the application loses the focus status, the <code>app_pause_cb()</code> callback is invoked. The application can go into the pause state, which means that your application is not terminated but continues to run in the background, when:</p>
<ul>
- <li>A new application is launched from the request of your application.</li>
+ <li>A new application is launched by the request of your application.</li>
<li>The user requests to go to the home screen.</li>
<li>A system event (such as an incoming phone call) occurs and causes a resident application with a higher priority to become active and temporarily hide your application.</li>
<li>An alarm is triggered for another application, which becomes the top-most window and hides your application.</li>

<p align="center"><img src="../../images/multiple_apps.png" alt="UI and service application life-cycle" style="display: block; text-align: center; margin-left: auto; margin-right: auto" /></p>

Basically, the service application is running in the background by its nature; so the platform does not allow the running of the service application unless it is designated as a background category application. However, when the UI application that is packaged with the service application is running on the foreground, the service application is also regarded as a foreground application and it can be run without a designated background category.</p>

The information can be insufficient to compute the Udate (you have only the year and the month, but not the day of the month), or the information can be inconsistent (such as "Tuesday, July 15, 1996" even though July 15, 1996 is actually a Monday).</p>

-<li><strong>Inconsistent information</strong> <p>If the fields conflict, the calendar prefers the most recently set fields.

+<li>Privacy name: Privacy name represents a group of privileges that are related to a certain privacy feature.</li>\r
</ul>\r
<p>Since Tizen 3.0, some privileges are categorized as privacy-related. The user can switch those privileges on and off as needed by changing certain privileges' status to allow or deny them at runtime. This means that the application calling a privileged API can be prevented from using it even if the required privilege is declared in its manifest file. Specific APIs can be used to check the privacy-related privilege's current status and get the display name of the privacy that includes the privilege. For example, you can use the APIs to check the privilege's current status before entering a function that requires the privilege, and if the status is off, display a guide message to the user to ask them to go to the device settings and switch the required privacy on.</p>\r
