Does that mean new design support library is not useful for FAB button below API 17 ? – Albin Mathew Jun 04 '15 at 05:58

This is known by Google and will be fix soon in the next version of the Design Support Library, see this issue: FAB Appears as a square on API 16. It should only concern API 16.
The workaround, proposed in the same thread, is to add app:borderWidth="0dp" to your FAB.

Finally the issue has been fixed in the new release
compile 'com.android.support:design:22.2.1'
this will solve the square layout issue in API 16. FAB performs well if you place it inside Coordinate Layout. Check out https://code.google.com/p/android/issues/list?can=1&q=label:Version-22.2.1 for issues and fixes in new version.

Released version 22.2.1 This release contains bug fixes related to FAB
https://code.google.com/p/android/issues/detail?id=175067
Change your gradle
compile 'com.android.support:design:22.2.1'
Install support repository revision 16. So you can avoid the workaround [app:borderWidth="0dp"]

If it helps, I solved my issue by removing
android:background
It was a remnant from the previous FAB library I used. The design library's gets the color automatically from colorAccent.
