Twilio in chrome extension - user denied access to microphone

Question

I am new to chrome extension. Is there a possibility of providing a microphone access permission to chrome extension by manual (javascript) or using manifest configurations.

I have included twilio successfully by downloading the twilio.js and changed the protocol to "https" for using in background.html of chrome extension.

Manifest.js fields are follows :

 "permissions":["http://*/*", "https://*/*", "*://mail.google.com/*", "storage", "unlimitedStorage", "contextMenus", "cookies", "tabs", "notifications", "activeTab", "background","identity", "*://*.twilio.com/*"],

"content_security_policy": "script-src 'self' 'unsafe-eval' https://apis.google.com https://*.twilio.com; object-src 'self' https://*.twilio.com",

Now,when extension made/receive a call using twilio and accepts the connection. It throws error from Twilio.Device.error method as follows

   error.message is **User denied access to microphone**.

Could anyone please help me to resolve this error ?

Answer 1

I have found an work-around way to enable twilio in the chrome extension's background page.

First time, when we install the extension into chrome app. Just create a new tab with dummy html from the extension directory as below code snippet and make a test call.

    chrome.tabs.create({'url': chrome.extension.getURL('/telephony.html')}, function(tab) {
        console.debug("Telephony Tab details are - ",tab);
    });

It will prompt the user for microphone access and provide allow permission. Once call connected, send a message to background page and setup the Twilio in background. Form the next time you can able to receive the calls in the background.
