When building the attached test project, the build fails with error:
`
/path/to/obj/Debug/aidl/IMxFrameworkService.cs(17,17): Error CS7036: There is no argument given that corresponds to the required formal parameter 'loader' of 'Parcel.ReadHashMap(ClassLoader)' (CS7036) (MobileAndroid)
`

The `IMxFrameworkService.cs` is the file generated from the AIDL file. There is this line of code in the `OnTransact` method:

`arg1 = data.ReadHashMap ();`

Note that there is no `ClassLoader` parameter. In the `Android.OS.Parcel` class, there is only one overload for the `ReadHashMap` method and it takes a `ClassLoader` (an abstract class) as an argument. There is no overload that takes no arguments. 

### Steps to Reproduce

1. Open the attached test project
2. Build the project

### Expected Behavior
Project will build

### Actual Behavior
build fails with error noted above.
