Therefore, currently, the process for ignoring SSL certificate errors on Android has diverged from iOS.

Instead, it includes the HttpClientHandler.ServerCertificateCustomValidationCallback property ( API doc). This implementation does not include the ServicePointManager API, because it’s not part of. In the last month, the new CoreFX implementation of HttpClient was dropped into the following Mono profiles:

However, in the last month it stopped working on Android and has left people wondering why. This approach worked for both iOS and Android. There are a number of approaches that can be used to work around this issue, but the typical approach was to use the managed HttpClient implementation in your DEBUG builds, and then set a callback for the that ignores the result of the localhost certificate check. This is because the local HTTPS development certificate is self-signed, and self-signed certificates aren’t trusted by iOS or Android. On iOS and Android, attempting to invoke a local secure web service from an app running in the iOS simulator or Android emulator results in an exception, even when the managed network stack is used. This process is documented at Connect to Local Web Services from iOS Simulators and Android Emulators. Bypassing the local development certificate check.Specifying the address of your local machine.Creating a self-signed developer certificate on your machine.However, it’s more work when the web service runs over HTTPS. During the development phase, it’s common to deploy a web service locally and consume it from a mobile app running in a simulator or emulator.Ĭonsuming localhost web services that run over HTTP is straight forward enough.
