I have been developing a Lightning app which allows me to preview using the /namespace/developername.app however after creating a managed package and publishing it returns the page no longer exists?

Any clues?

    Did you try "/c/developername.app" ? Commented Jun 21, 2015 at 21:22
  • c is available before you set up a managed package namespace. After that c/ is no longer available. Commented Jun 22, 2015 at 12:01
  • try to use this one /one/one.app the standard lightning application URL you've created Commented Sep 21, 2015 at 2:43
  • /one/one.app no longer works unless you set your browser to emulate a mobile browser

From Lightning Components Developer Guide; "Mark your resources with access="global" to make the resource usable outside of your own org; for example, if you want the resource to be usable in an installed package or by a Lightning App Builder user or a Community Builder user in another org."

So, please add GLOBAL access modifier to your app like; aura:application access="GLOBAL"
