This tutorial will assist you with the steps of the widget development process using a simple widget. Step 1: Preparation Step 2: Basic Widget Functionality Step 3: Advanced Applications |
Lesson 2: The widgetPackage.xml file
The structure of widgetPackage.xml file should look like this:
<?xml version="1.0" encoding="utf-8"?> <widgetPackage xmlns="http://xmlns.sony.net/mylo/widget" version="1.0"> <info> <packageName>Simple Widget</packageName> <author>Sony Electronics Inc.</author> <abstract>Simple Widget for practice</abstract> <version>1.0</version> <locale>US</locale> <engine>1.0</engine> <updateURL></updateURL> <downloadURL></downloadURL> <siteURL></siteURL> <minWidth>21</minWidth> <maxWidth>66</maxWidth> <defWidth>21</defWidth> <defHeight>17</defHeight> <createDate>2008-01-01</createDate> </info> </widgetPackage>
Although updateURL, siteURL and downloadURL are not used in this simple widget, we included them in this example as they are important to know about for later widget development.
