Ok, I have managed to solve my problem with downloading a file, just
for information, if You have the same issue just do these things I
wrote down bellow.
But I'm still in need to be able to track user log ins. And I
don't know why when I'm clicking on html input I'm able to only choose
file from my storage and can't take photo ? I've got my android app
created using cordova.
Add to your manifest
and to res -> xml -> new file network_security_config with
following lines of code
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<domain-config>
<domain includeSubdomains="true">example.pl</domain>
<trust-anchors>
<certificates src="@raw/path_to_cert"/>
</trust-anchors>
</domain-config>
</network-security-config>
