trusted CAs do not work on android 7

[nmitsou]

Hi, When adding a website with a self-signed certificate on android 7, you get an exception: Trust anchor for certification path not found. To fix it, you can add a network_security_config.xml and use it on AndroidManifest (e.g. https://github.com/bfabiszewski/ulogger-android/commit/62cefe9d550c4d91c07ef995f8c409d21a984bad)

Can confirm that this error appears to me as well.
