OkHttp binding library for Xamarin Android throwing error

Question

I'm attempting to use the OkHttp-Xamarin library in a Xamarin Android application. Whenever I try to create a new OkHttpNetworkHandler I get the exception below.

Line:

var handler = new OkHttpNetworkHandler();

Throws:

[] Missing method Android.Runtime.JNIEnv::AllocObject(Type) in assembly Mono.Android.dll, referenced in assembly /data/data/com.my.app/files/.__override__/OkHttp.dll
[MonoDroid] UNHANDLED EXCEPTION: System.MissingMethodException: Method not found: 'Android.Runtime.JNIEnv.AllocObject'.
[MonoDroid] at ModernHttpClient.OkHttpNetworkHandler..ctor () <IL 0x00001, 0x00057>

I am using prebuilt binaries from ModernHttpClient version 0.9. My minimum Android version is set to 2.3 and target is set to 4.2. I'm using Xamarin Studio 4.0.13 and Mono 3.2.3.

Answer 1

So this looks like the first call to your binding code.

A couple things could be going on here:

• Make sure you are using EmbeddedJar instead of InputJar as the build action for the jar file. Otherwise, you have to include the jar with your main Android application.
• Make sure your main application has a reference to the binding DLL, it causes problems if only a dependent project has the reference.

If neither of those fix your issue, let me know, I think there is a working binding Paul Betts has for this library.

Answer 2

Not really an answer to why the Exception is being thrown but at the suggestion of Paul Betts I switched to the Alpha channel and things are working now.
