Can you provide a minimal repro? I do not see this error with the following project:

Looking at the relevant code:

https://github.com/dotnet/java-interop/blob/4f06201b598ac3816184ea7a0b71f540f6abe9d6/src/Java.Interop.Tools.JavaTypeSystem/Adapters/ManagedApiImporter.cs#L194-L195

This appears to be a case where:

• We are trying to import a referenced Android binding .dll.
• A method in that .dll has a [Register] signature that specifies that the method has N parameters, but the method actually has a different number of parameters.

Example: here (I) means the method takes a single int parameter, but the managed method actually takes no parameters.

[Register ("doThing", "(I)", "")]
public unsafe void DoThing () { ... }

@jpobst Here is the binding source code.

BTW, I attempted to debug this source, but failed following the guidelines. Can you advise?

io.ktorktor-utils-jvm.2.3.8.zip

I get this error trying to build this project:

C:\Program Files\dotnet\packs\Microsoft.Android.Sdk.Windows\34.0.145\tools\Xamarin.Android.Common.targets(893,3): error XACDJ7028: System.IO.FileNotFoundException: Could not find file 'C:\Users\jopobst\.gradle\caches\modules-2\files-2.1\org.slf4j\slf4j-api\1.7.36\6c62681a2f655b49963a5983b8b0950a6120ae14\slf4j-api-1.7.36.jar'.

I'm not sure how this file is supposed to get to that path, though I do have a 1.7.30 version there.

@jpobst Can you install Gradle and/or Android Studio? The other dependencies require gradle to download Android artifacts.

[tuyen-vuduc]

@jpobst Have you been able to check it out? Any chances to guide me to debug on my machine?

I already have Android Studio on my machine, so it apparently requires something more than that.

Any chances to guide me to debug on my machine?

To debug locally, you would need to:

• Clone this repository
• Get Java.Interop.sln building on the command line
• Open generator.slnf in VS
• Get the failing command line from your failing build (likely using binlog)
• Debug in VS using that startup command line

@jpobst I managed to build and run this repo. however, I tried to replicate the issue, it shows error differently. Can you guide how we can by pass this error for common libs? And/or jump into JavaInterop source during the build in VS?
