绑定 aar Visual Studio (Xamarin)

Question

我在 Visual Studio 中使用 xamarin，我尝试 link 文件（java 到 C#）我正在使用库绑定 (android) 来集成文件，但对于某些方法，此过程转换为失败。

错误信息

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

我尝试配置元数据，但无法解决这些错误已经有人看到这个问题了。。你知道怎么解决吗？？

Answer 1

您的问题很可能在这里：

<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>

正如您在这里看到的，方法 doInBackground returns com.ingomoney.ingosdk.android.http.json.response.base.MobileStatusResponse 并采用 java.lang.Object... 的参数。这需要与界面所期望的完全匹配，如果不匹配，您需要 "dumb" 向下对象类型。

简而言之，您运行获得部分泛型支持，http://docs.xamarin.com/guides/android/advanced_topics/limitations/#Partial_Java_Generics_Support

您可以做几件事：

创建错误 class 的部分 class 并在内部创建覆盖：

即

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

如果您打算完全不使用此 class，请使用 <remove-node> 删除 class：https://gist.github.com/JonDouglas/dda6d8ace7d071b0e8cb#removing-types

Metadata.xml 中也有解决此问题的方法，但我必须查看示例。理想情况下，您可以更改 managedReturn、managedType，甚至 argsType。
