Exporting Apk ( Problem Parsing Package )

When I try to export my test app and then test it on Samsung s4, I get error Problem Parsing Package. I am exporting the Debug apk and I have enabled developer mode on my phone. Anyone know whats wrong?

Here is the Apk I exported if you want to try to run it on a phone.

Here is the Project file if you want to try to export it.

It is a simple test app that just makes a dog sound when you hit the button.

Additional to enabling Developer mode, did you also enable USB debugging option?

No I didn't do that till just now, but it still will not install my apk even with usb debugging on. Thanks for the reply tho.

Thylacine I guess the issue is your android os, as minimum os requirement is 5.0 lollipop.

app is working on my device Galaxy J7 -OS marshmallow

You was right Drago_18 my android version was too old, thanks!
