I have created the Lightning Component by implementing following interface
implements="force:appHostable,flexipage:availableForAllPageTypes,force:hasRecordId,forceCommunity:availableForAllPageTypes"
Also Created Lightning Tab & added in the Mobile Navigation , hence i can be able to access the lightning tab in SF1.
But if i logged in system admin in community, i can't be able to see the particular tab in SF1. How can i able to access the tab in communities(in SF1), also is there any other way i can be able to show the lightning component directly in community(in SF1)?
