Implementing MobileIron SDK. Which HttpClient use?

I need to intagrate MobileIron SDK in Android app. The app use Retrofit library. But MobileIron documentation says:

HTTP Redirect for HTTP Tunneling is not supported for the following classes (which do support HTTP Tunnel)

1. java.net.HttpURLConnection
2. java.net.ssl.HttpsURLConnection
3. AndroidHttpClient

and

HTTP Tunneling when using non-standard libraries such as the following:

1. com.squareup.okhttp.HttpClient
2. Apache HttpClient library that has been repackaged under the ch.boye.httpclientandroidlib package

How can I replace Retrofit in app, if documentation says, that I can not using HttpURLConnection ?

I think you may use MobileIron AppConnect 7.5.4 for your Retrofit library, since Retrofit library depends on OkHttp API.

Supported APIs

An AppConnect app can use HTTP/HTTPS tunneling only if the app accesses the enterprise server using one of the following APIs:

• java.net.HttpURLConnection
• java.net.ssl.HttpsURLConnection
• Android HttpClient

• DefaultHTTPClient, using the standard Apache HttpClient library with the org.apache.http.package name

  Note: HTTP/S tunneling is not supported with non-standard libraries such as the Apache HttpClient library repackaged under the ch.boye.httpclientandroidlib package.

• OkHttpClient

• ModernHTTPClient in apps built with the Xamarin development platform.
