    'm running Unity 2019.1.6f1 and testing with a Pixel 3. On creating a new connection this scene freezes.
    Client client = new Client("http", "[addressofmyserver].com/", 7350, "defaultKey");

    When I run logcat I'm seeing this error:
    Unable to find libc

    Then if I try to create a session it results in a null exception, as the client wasn't created due to the libc error.

    NullReferenceException: Object reference not set to an instance of an object

    I've tried changing build settings and targets, but no improvements.'

    Wow, cool post. I’d like to write like this too – taking time and real hard work to make a great article… but I put things off too much and never seem to get started. Thanks though.
