I have a crash in a Xamarin app that is using the Twilio Client Component. I use the "Getting Started" code to make a simple app that makes a phone call out when I click a button. From the crash log I see a reference to "CRASHING_DUE_TO_PRIVACY_VIOLATION" in the call stack. I don't know what that could be as I have "Audio and Airplay" and "Voice over IP" check in background modes in my apps plist file.
The odd thing in in simulator it works perfect, the crash only occurs when I run the app on the iPhone. My phone is running ios 10.2. I am including the code and the crash log. Please help as this crash occurs exactly the same way in an app I am building for work so I really need to solve it and I am at my wits end.
using System;
using UIKit;
using Foundation;
using TwilioClient.iOS;
namespace twiliotest
{
public partial class ViewController : UIViewController
{
TCDevice _device;
TCConnection _connection;
protected ViewController(IntPtr handle) : base(handle)
{
// Note: this .ctor should not contain any initialization logic.
}
public override void ViewDidLoad()
{
base.ViewDidLoad();
string sLink = "https://www.myserver.com/captok.php";
var url = new NSUrl(sLink);
var data = NSData.FromUrl(url);
var token = data.ToString();
// Create a new TCDevice object passing in the token.
_device = new TCDevice(token, null);
}
public override void DidReceiveMemoryWarning()
{
base.DidReceiveMemoryWarning();
}
partial void ButtonCall_TouchUpInside(UIButton sender)
{
if (_connection == null || _connection.State == TCConnectionState.Disconnected)
{
var param = new TCConnectionParameters
{
From = "12125551234",
To = "12125554321"
};
_connection = _device.Connect(param, null);
}
else {
_connection.Disconnect();
}
}
void SetupDeviceEvents()
{
if (_device != null)
{
_device.ReceivedIncomingConnection += (sender, e) =>
{
_connection = e.Connection;
_connection.Accept();
};
}
}
}
}
Here is the crash log. Note the crash is in thread 7.
