android - Security Privilege Error - Samsung Gear SAP

Question

I'm following the Samsung SAP provider/consumer tutorial and I'm getting a security error when I run the connect() method:

function connect() {
    console.log("trying to connect");
    document.getElementById('label').innerHTML = 'trying to connect';
    if (SASocket) {
        alert('Already connected!');
        return false;
    }
    try {
        webapis.sa.requestSAAgent(onsuccess, onerror);
    } catch(err) {
        console.log("exception [" + err.name + "] msg[" + err.message + "]");
        document.getElementById('errorlabel').innerHTML = "exception [" + err.name + "] msg[" + err.message + "]";
    }
}

js/main.js (74) :exception [SecurityError] msg[The application does not have the privilege to call this method.]

In my config.xml I have:

<tizen:privilege name="http://devloper.samsung.com/privilege/accessoryprotocol"/?

Do I need anything else e.g. a certificate? I can run the sample projects no problem without my own certificate but do I need a certificate if I created the app myself from scratch?

Update - Solution: Two things - 1. typo! devloper should be developer - 2. @Nana Ghartey is also correct - a certificate is needed to test on the device, get this by sending a CSR to Samsung (details on their developer site).
