I need to work with the android-support-v4, buy when i try to install it from SDK manager (support library), it does not show me the package, actually i wanted to install anothe
With the new SDK Manager installed, you will find the "Android Support Library" under Extras (if sorted by API level) or under the repository "Google Inc" (if sorted by Repository).
I had exactly the same view as above, searched all over the Net, incl this post, and couldn't find anything. By the time I gave up, it suddenly showed in my listings. It seems that I had some network issues (possibly combined with latest version).
