Description Jeremy Kolb 2014-12-02 11:39:58 UTC
The constructor for InputStreamReader is:

[Register(".ctor", "(Ljava/io/InputStream;)V", "")]
public InputStreamReader(Stream @in)

But in this case Stream is resolving to System.IO.Stream instead of Java.IO.InputStream
Comment 1 Jonathan Pryor 2014-12-02 15:16:24 UTC
This is by design. We "hide" many Java types in public APIs to more readily consumable .NET equivalents. In this case, we're replacing InputStream with System.IO.Stream (similarly OutputStream), we'll replace many Android XML parser types with System.Xml equivalents, etc.

This is to facilitate code reuse, so that you can more easily pass existing .NET code to Java code.

...though we should probably expose the "original" Java members for methods and constructor parameters.

As per the comment 1, this is by design. Hence I am marking this issue as "Resolved Answered".
