I followed all the steps correctly after seeing it`s not working I uninstalled and began all installation afresh and still the icon does not appear. Should I downgrade eclipse to luna4.4?Or how do I solve this problem?My java version is 1.7.0_80
First I changed my eclipse version to luna 4.4 then followed this guideline https://developers.google.com/eclipse/docs/install-eclipse-4.4 and the icon appeared.
