绑定aar Visual Studio（Xamarin）

我在Visual Studio中使用xamarin，并尝试链接文件（java到C＃）我正在使用库绑定（android）来整合文件，但对于某些方法这个过程转换失败。绑定aar Visual Studio（Xamarin）

错误消息

Class X does not implement inherited abstract member 'AsyncTask.DoInBackground (params Object [])'

我尝试配置的元数据，但我解决不了这些错误有人已经看到这个问题..你知道如何解决？

“doInBackground”的API xml描述是什么？ – SushiHangover

API xml？对不起..这是我的第一个exp与xamain绑定..在哪里我可以看到API xml？ ..tnks –

'obj \ Debug \ api.xml'为自动生成的：https：//developer.xamarin.com/guides/android/advanced_topics/binding-a-java-library/customizing-bindings/ java-bindings-metadata /＃概述 – SushiHangover

您的问题最有可能就坐落在这里：

<method abstract="false" deprecated="not deprecated" final="false" name="doInBackground" native="false" return="com.ingomoney.ingosdk.android.http.json.response.base.MobileStatusResponse" static="false" synchronized="false" visibility="protected"> 
<parameter name="p0" type="java.lang.Object..."> 
</parameter> 
</method>

正如你可以在这里看到，doInBackground返回com.ingomoney.ingosdk.android.http.json.response.base.MobileStatusResponse，并采取了参数的方法java.lang.Object...。这需要完全匹配接口所期望的内容，如果没有，你需要“哑”对象类型。

在你正在运行到部分泛型支持短，http://docs.xamarin.com/guides/android/advanced_topics/limitations/#Partial_Java_Generics_Support

有几件事情可以做：

创建一个局部类有过错的类和内创建替代：

即

protected override Java.Lang.Object DoInBackground(params Java.Lang.Object[] params){...}

如果您打算不是在所有使用这个类，使用<remove-node>删除类：https://gist.github.com/JonDouglas/dda6d8ace7d071b0e8cb#removing-types

有办法在Metadata.xml解决这个问题为好，但我不得不看一个样本。理想情况下，您可能会更改managedReturn,managedType或甚至argsType。
