Network capture

Xamarin provides various options to request data from remote services (via HTTP, FTP, etc.). Some of them are quite easy to intercept while others need additional actions in your code.

Capturing network in Android and iOS apps

This section describes network APIs, whose network events can be captured the same way for Android and iOS apps.

HttpWebRequest / HttpWebResponse

All requests made with WebRequest.Create('https://domain.com') are captured automatically and do not require any changes in your code. Bugsee will capture all the data passed through the returned HttpWebRequest instance.

Capturing network in an iOS app

Bugsee captures network requests from the following classes:

HttpClient

When using HttpClient check the back-end you are using for it. Xamarin offers 3 options (can be selected in project settings):

• NSUrlSession
• Managed
• CFNetwork

NSUrlSession case will work out of the box, others require a minor change to your code. Bugsee provides a custom message handler which needs to be hooked to every HttpClient instance upon construction:

using System.Net.Http;
using BugseePlugin;

// replace this:
var httpClient = new HttpClient();

// with this:
var httpClient = new HttpClient(Bugsee.GetHttpMessageHandler());

// Send requests as usual
// ...

NSUrlConnection

All requests made with NSUrlConnection are captured automatically and do not require any changes in your code.

Capturing network in Android app

Bugsee provides methods to capture HttpClient and ModernHttpClient network events.

HttpClient

Bugsee provides a custom message handler which needs to be hooked to every HttpClient instance upon construction:

using System.Net.Http;
using BugseePlugin;

// replace this:
var httpClient = new HttpClient();

// with this:
var httpClient = new HttpClient(Bugsee.GetHttpMessageHandler());

// Send requests as usual
// ...

Wrapping existing HttpClientHandler (iOS and Android)

If you have your own HttpClientHandler or its implementation is provided by some third-party, you can wrap it with handler provided by Bugsee, to let us capture all the network requests made through that handler.

Consider an example with ModernHttpClient, which works very similar to HttpClient:

using System.Net.Http;
using BugseePlugin;

// replace this:
var httpClient = new HttpClient(new NativeMessageHandler()); // NativeMessageHandler comes from ModernHttpClient library.

// with this:
var httpClient = new HttpClient(Bugsee.GetHttpMessageHandler(new NativeMessageHandler())); // Wrap NativeMessageHandler.

// Send requests as usual
// ...
