The .apk file can be downloaded from the phone and installed directly or if you have it on the computer, simply connect the phone by USB cable and pass the file to the memory of the device.
Google allows you to activate or deactivate this option so that you can exploit Android resources, although yes, in the small letters you read "at your own risk".
