There was some sample codes in the resource section, explaining some examples, that now are gone.
i.e http://developer.android.com/resources/samples/TicTacToeMain/index.html
when click on them it takes you to http://developer.android.com/tools/samples/index.html
any help regarding this ?

What you can do is download the Samples from this link http://developer.android.com/tools/samples/index.html and then follow these steps to get it running on Eclipse:
File ->New -> Android Project -> Create Project from existing sample -> Select the version(for which you have downloaded the Samples) -> Select the Sample.
In this way you can import the sample reference program provided by android and it will help you in getting good hold of its API’s.
