Trouble to get installable apk

I have created todo list application, following official Meteor tutorial. I wanted also create native Android application from this, but I wasn’t successful.

I used this as a roadmap to get installable apk (I don’t want put anything to Google play, all this is just for learning purposes) ->

Every time I get apk file, but I can’t intsall it on my Android phone or Android tablet. Install button just does nothing.

Hard to believe that I’m only guy with this kind of problem.

I dont’ have any error messages, just can’t go forward from this screen, Install button does nothing.

Can someone help please?
