Cant build App - Unable to install APK to device

Hi,
want to build my first app , have tried different ways an got straight from failure to failure.
Now i can build the App but have Problems to get that on my Test phone. (Samsung galays A3 2016)

I get the massage Unable to Install APK to device.

Have changed the settings from Storage to Automatiic.
Dont know what to do now....
I think SDK is installed correctly ( have changed the Version of Tools to 25.2.5
because of build errors earlier.)

Any help for me ?

problem solved .

 

How did you solve this? I'm running into something similar.

 

+1 to this, would be nice to know how you solved it. I am having the exact same problem.

 

I have same erorr

 

What's the point of opening a thread if you are not sharing the solution to the problem?

 

Plz solve .

 

A solution that worked for me when having problems with the Android.apk was to uninstall the app on my phone and re-building the app after that. Try it out!

 

It works for me!
