Writing your First Mobile App for Nokia

This is the next step of my journey towards mobile development. I want to introduce you with Nokia's Symbian Web Runtime (WRT) technology, and show you how easy it is to write your first WRT widget application.

You must have basic knowledge of HTML, CSS and JavaScript and you are ready!!

Step1 :- Write your application with HTML, CSS and JS, and test it in browser. You can start with alerting "Hello" or a simple calculator to add two digits. Feel free to use JS libraries like jQuery etc. Put all these files to a folder. For example "HelloApp".

Step2 :- Create an info.plist file in the same folder there your main HTML file is situated.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Nokia//DTD PLIST 1.0//EN" "http://www.nokia.com/DTDs/plist-1.0.dtd">
<plist version="1.0">
<dict>
  <key>DisplayName</key>
  <string>Hello</string>
  <key>Identifier</key>
  <string>com.Hello.basic.widget</string>
  <key>Version</key>
  <string>1.0</string>
  <key>MainHTML</key>
  <string>index.html</string>
</dict>
</plist>

In this file you must put the "DisplayName" (You can put anything), "Identifire" (Something like com.anything.anything) and your "MainHTML" ( Main HTML file name).

Step3 :- Zip your folder and rename it to ".wgz" from ".zip". As example HelloApp.zip to HelloApp.wgz

Step4 :- Install it to your Nokia S60 or S40 phone.
