Running Native Code on Android Presentation by Cédric Deltheil StackOverflow: How to build c-ares library in Android (NDK) StackOverflow: Include. It turns out that Android requires the root certificate with SSL.įor more details, please refer to this doc: Android Native Development Kit (NDK), and included documentation.
To solve this, the server doesn't send the client only it's certificate during the SSL handshake, but a chain of certificates from the server CA through any intermediates necessary to reach a trusted root CA. Īs the native Android document describes, Android typically trust only root CAs directly, which leaves a short gap of trust between the server certificate-signed by the intermediate CA-and the certificate verifier, which knows the root CA. Or is this the expected behaviour by design? Is there any plans on fixing this on Xamarin.Android? We’re stating that we’re using the latest CMake in Android Studio (3.6.0), and that we’re building a shared library called helloworld-c. Once we did this, Xamarin.Android performed a successful handshake.Ī wild card certificate alone should be enough to perform an SSL handshake. To fix this problem, we had to link the root and the intermediate certificate to the wildcard certificate in the server. This can be done using the SDK Manager that is part of Android Studio. Before you can build curl for Android, you need to install the Android NDK first. When the server only has the wildcard certificate key chain, Xamarin android fails to perform a successful SSL handshake. When building curl for Android its recommended to use a Linux environment since using curls configure script is the easiest way to build curl for Android.
