I'm trying to build an android binding library for LINE SDK (a SNS service popular in Asia area). I added the jar file from the SDK into my project but it fails to compile because the creators of the SDK just happen to use the same name for a class and its property.

This is part of the C# code that the project generated from the jar file

```
public partial class AccessToken : global::Java.Lang.Object {
    // Metadata.xml XPath field reference: path="/api/package[@name='jp.line.android.sdk.model']/class[@name='AccessToken']/field[@name='accessToken']"
    [Register ("accessToken")]
    public string AccessToken {
        get { /* ... */ }
        set { /* ... */ }
    }
//...
}

```

Now simply put, I want to know how I can rename this property "AccessToken". I tried adding some commands in Metadata.xml but it had no effect. Here's a line of what I've written for reference

```
<attr path="/api/package[@name='jp.line.android.sdk.model']/class[@name='AccessToken']/field[@name='accessToken']" name="propertyName">AccessTokenString</attr>

```

I'd be grateful if somebody could help me out. I'm totally lost here.
