Is it possible to embed the Unreal Engine into a mobile application?

I’m developing mobile applications for Android and iOS
and would like to be able to run games inside them.

I don’t want to use an application generated by the engine.
What I need is the possibility to run the contents form the application.

Is it possible with the Unreal Engine?
What effort would be needed to do it?
