My android build crashes on run

So I’m creating a development android build of my game (first screenshot).

Once completed it outputs the files shown in screenshot number two.

I moved the .apk file to my Samsung Galaxy S4 and install my game.

However when it runs, it instantly closes back to my android desktop.

Am I doing something wrong?
