If you want to simply install the application to the phone, to check its functional, then you need to go to the folder where you have a project and go to the App \ Build \ Outputs folder, you will have file app-debug.apk.
This file you copy to your phone and through the FileManager program, find it and install it.
What you did, it is necessary in order to create a unique certificate for your application (it is necessary to post the application in Google Play Market).

p.c. Do not copy the App-debug-unaligned file. Each time you compile the project, your App-Debug.apk

file will be updated.
