I want to install ADT plugin in Eclipse with Zip file but when i click on next button in first page of install, the progress late long time. I wait around 3hours that i wait
Even when you are installing ADT using zipped file, You need internet connection to complete installation.
If the site is blocked, the only way is to copy-paste the eclipse folder from your friend's system, who are using the same platform and already installed ADT plugin.
One more step: Make sure the SDK location is correct.
Window -> Preferences -> Android. Here, make sure you use the correct SDK Location.
