I googled on the keywords Android and widgets, hoping to find clear definition of a widget. But all the definitions are vague and could be applied to any apps.
My feeling is that a widget is a small app that runs in the background at all times, as a separate thread. Usually, it displays something or waits for input at all times. As opposed to an app that has to be started/terminated explicitly when the need arises. If this is the definition of a widget then it is the oldest concept in multi-tasking operating system where such concept used to be called a background process. If this is so, then why it is said that widgets are unique to Android. I bet iPhone has them too but under a different name. What is so unique about widgets?

It rather depends on what help you need. We cannot do your work for you, but will try to help resolve problems with code that you have written. Your question lacks any real detail that could help us to help you, so I can only suggest you look at some of the articles at http://www.codeproject.com/KB/android/#Android+Tutorial+Contest[^] as a first step.
Need help I have tried everything, I have installed IntelliJ reinstalled (5 times) Eclipse finally got it working.
Took advice of ppl here and also build path changed Workspace and I still get R.cannot be resolved in my Eclipse Juno I checked my main.xml corrected my Android Manifest XML and i am still stuck with this error can someone pls help me?
Have a look in your project's generated files directory tree, (mine is C:\Users\My Documents\Android\BaseTest\gen\com\example\basetest) for a file named R.java. If you don't have one then your project is not getting built correctly. Try a manual build and look at the messages that get produced.
BTW please don't offer 'incentives' to get people to help you; it looks cheap.
There are many versions of Eclipse. Alas, Juno is one version that has more problems (bugs) with Android than other version. I suggest you remove Juno and download and use either Indigo or Kepler versions of Eclipse. They are more "stable" for Android development.
ALSO, if you want to contribute to the community as a way of "paying back to the community", then write an article or go into the forums and help out answering questions. Never attempt to bribe a CP member for an answer to your question. It isn't the done thing.
In my experience, when the R.java file cannot be created, it usually means a problem with one or more .xml files. It likely won't help to refresh/clean the project if a .xml file is in error, as the R.java file will still fail to get created.
Have you looked at the Problems tab?
Another thing to try is to open each (layout) .xml file and click the Graphical Layout tab. It will complain about stuff that the other tab will not.
