Hmm I might have misunderstood then. I thought that the android apps would be available themselves. If the developers have to adapt them to run on W10 then most probably they won't be available in the near future. Hopefully they will though.
But Microsoft made it easy steps by project Astoria. I.e by modifying the android code with few steps to adapt windowsmobile. Currently tinycamera app for android ready to come to windows mobile 10. Similarly hoping for others. I even contacted some popular apps dev but no reply.

If you watched the W10 keynote at BUILD it mentioned this and corrected the misunderstanding. There's a iOS app that's been used for some time that used the tools that MS has created for doing the port. They will have one for Android and iOS.
