Packaging on Mono for Android doesn't like Newtonsoft.Json.Android.

[manadart]

Hi Guys,

This one's strange.

I originally had a build of Newtonsoft.Json.MonoDroid in a solution I'm working on. I noticed your MonoDroid build includes the same library, but named Newtonsoft.Json.Android. So I removed my version and included yours.

The solution built fine, but deploying fell over with a message that Newtonsoft.Json.MonoDroid could not be found. It worked when I added my reference back in.

After trying for ages to coerce the thing into a successful deployment, I think I've discovered a quirk in Mono for Android. You see, despite your binary being named Newtonsoft.Json.Android, the assembly is still named Newtonsoft.Json.MonoDroid, which Mono for Android must be looking for when it attempts to package the solution files.

Has anyone else encountered this?

I don't work with Mono for Android but can you verify this with a standalone test case?

[manadart]

Sure. I'll do so when I have some time.

[johnsheehan]

Any luck with this?

[manadart]

Sorry for the tardiness.

I created a new Mono for Android project - no changes. Added the references to RestSharp.Android and Newtonsoft.Json.Android. Deployed.

This is the output:

I also tried after upgrading Mono for Android from 4.0.1 to 4.0.3.
The result is the same.

[manadart]

Changing the file name to Newtonsoft.Json.MonoDroid and updating the reference is all that is required to rectify.

Can you do a pull request with those changes?

Pull request #207 fixed this issue.
