How to export games from UE4 to iOS or Android?

I been trying to create a game in Unreal ENgine 4 already and then I just want to test it that it work on iOS or Android or not! So anybody who can help me to do this??

Thank in advance!

You need to package your project to specific platform, here docs with info how to setup things for that

But I package my projects to specific platform always Fail!
Do u know why??

Gamingroom, could you post a log of the failure? You can get to it by selecting the show log link in the Packaging progress in the bottom right corner of the editor. That would help us determine what the problem might be.
