Android N Preview 2 adds method parameters which are not valid C# identifiers, and these weren't being properly handled before. Fix parameter identifiers so that invalid characters such as `$` are replaced with `_`.
Comments are inserted into the generated C# code to identify the emitted member with the "source" XML declaration, to permit later fixups via metadata without the drudgery of manually determining the XPath references. Unfortunately, when a class implements an interface, the generated XPath comment for the interface method within the class would provide an XPath expression "as if" the method were declared in the class, which was not the case: // Metadata.xml XPath method reference: path="/api/package[@name='java.util']/class[@name='AbstractCollection']/method[@name='spliterator' and count(parameter)=0]" [Register ("spliterator", "()Ljava/util/Spliterator;", "GetSpliteratorHandler", ApiSince = 24)] public virtual unsafe Java.Util.ISpliterator Spliterator () Above, the spliterator() method is *actually* declared in java.util.Spliterator<T>, but the comment implies that the generated method is coming from java.util.AbstractCollection<T>. The comment is thus wrong, as AbstractCollection.spliterator() doesn't exist within the API XML (it's implied by the implemented interfaces). To fix this, use the Method's DeclaringType in the XPath comment: // Metadata.xml XPath method reference: path="/api/package[@name='java.util']/class[@name='Spliterator']/method[@name='spliterator' and count(parameter)=0]"
In Android N Preview 2, `java.util.Iterator<E>` adds a `spliterator()` method, which is overriden in `java.util.Collection<E>`. That resulted in our generator to emit duplicate binding methods for *both* `spliterator()`s -- one from the `Iterator<T>`interface and one from the `Collection<T>` interface -- within implementing classes such as `java.util.AbstractCollection<T>`. The most derived override should be the one to invoke, so generate Java Callable Wrappers for only the most overridden ones (`java.util.Collection<T>.spliterator()` in this case). To do so, first mark them as overides, and then exclude those overriden from the generated code.
Android N Preview 2 adds several static methods to the
java.util.Comparator<T> interface, such as `reverseOrder()`:
/* partial */ interface Comparator<T> {
public static <T extends java.lang.Comparable<? super T>>
java.util.Comparator<T> reverseOrder();
}
DO NOT BIND Java interface static methods within C# interfaces.
It doesn't make conceptual sense, and results in unusable bindings.
If we bind those methods into interfaces, our users will have to implement those methods unlike Java8, and that's more annoying than missing them. Related: dotnet#25
