@qcjxberin: @(AndroidMavenLibrary) "just" adds support for automagically downloading Maven artifacts based on their ID, and validation support to ensure that the closure of all dependencies are present.

It doesn't change how bindings otherwise work, and the binding process is (unfortunately) not perfect; see also: https://github.com/dotnet/java-interop/wiki/Troubleshooting-Android-Bindings-Issues

Unfortunately I can't read Chinese, but fortunately you provided a repro. Oddly, I get a different set of warnings and errors than you do…

1:7>obj/Debug/net9.0-android/api.xml.class-parse : warning BG8605: The Java type 'java.awt.Color' could not be found (are you missing a Java reference jar/aar or a Java binding library NuGet?)

This is concerning, as (1) your warning and error list doesn't have this warning, and (2) Android doesn't provide the java.awt package, so this is not solvable.

You'll just need to ignore warnings like this.

obj/Debug/net9.0-android/generated/src/Com.Alibaba.Fastjson.Util.AntiCollisionHashMap.cs(175,103): error CS0508: 'AntiCollisionHashMap.EntrySet()': return type must be 'ICollection' to match overridden member 'AbstractMap.EntrySet()'

If you go to Com.Alibaba.Fastjson.Util.AntiCollisionHashMap.cs, you'll see this surrounding context:

		// Metadata.xml XPath method reference: path="/api/package[@name='com.alibaba.fastjson.util']/class[@name='AntiCollisionHashMap']/method[@name='entrySet' and count(parameter)=0]"
		[Register ("entrySet", "()Ljava/util/Set;", "GetEntrySetHandler")]
		public override unsafe global::System.Collections.Generic.ICollection<global::Java.Util.IMapEntry>? EntrySet ()

Copy the path=… value from the comment, and then add a new entry to Transforms\Metadata.xml which:

1. Uses the <attr/> element.
2. Copies the path=… value from above
3. Uses name="managedReturn" to alter the return type.

Thus:

  <attr path="/api/package[@name='com.alibaba.fastjson.util']/class[@name='AntiCollisionHashMap']/method[@name='entrySet' and count(parameter)=0]"
      name="managedReturn">System.Collections.ICollection</attr>

(One error fixed, 13 to go!)

While this appears to work in the short term, eventually it fails:

obj/Debug/net9.0-android/generated/src/Com.Alibaba.Fastjson.Util.AntiCollisionHashMap.cs(180,12): error CS0266: Cannot implicitly convert type 'System.Collections.Generic.ICollection<Java.Util.IMapEntry>' to 'System.Collections.ICollection'. An explicit conversion exists (are you missing a cast?)

So the actual fix is to rename the method, and use a partial class to glue things together:

  <attr path="/api/package[@name='com.alibaba.fastjson.util']/class[@name='AntiCollisionHashMap']/method[@name='entrySet' and count(parameter)=0]"
      name="managedName">_EntrySet</attr>
  <attr path="/api/package[@name='com.alibaba.fastjson.util']/class[@name='AntiCollisionHashMap']/method[@name='entrySet' and count(parameter)=0]"
      name="managedOverride">virtual</attr>

using System.Collections;

namespace Com.Alibaba.Fastjson.Util {
    partial class AntiCollisionHashMap {
        public override ICollection EntrySet() => (ICollection) _EntrySet();
    }
}

obj/Debug/net9.0-android/generated/src/Com.Alibaba.Fastjson.JSONArray.cs(20,131): error CS1721: Class 'JSONArray' cannot have multiple base classes: 'JSON' and 'List'

The offending line:

public partial class JSONArray : global::Com.Alibaba.Fastjson.JSON, global::Java.IO.ISerializable, global::Java.Lang.ICloneable, global::Java.Util.List, global::Java.Util.IRandomAccess {

@jpobst: this feels like a generator bug. How is Java.Util.List getting there?

api.xml.fixed contains:

    <class abstract="false" deprecated="not deprecated" extends="com.alibaba.fastjson.JSON" extends-generic-aware="com.alibaba.fastjson.JSON" jni-extends="Lcom/alibaba/fastjson/JSON;" final="false" name="JSONArray" static="false" visibility="public" jni-signature="Lcom/alibaba/fastjson/JSONArray;">
      <implements name="java.io.Serializable" name-generic-aware="java.io.Serializable" jni-type="Ljava/io/Serializable;" />
      <implements name="java.lang.Cloneable" name-generic-aware="java.lang.Cloneable" jni-type="Ljava/lang/Cloneable;" />
      <implements name="java.util.List" name-generic-aware="java.util.List&lt;java.lang.Object&gt;" jni-type="Ljava/util/List&lt;Ljava/lang/Object;&gt;;" />
      <implements name="java.util.RandomAccess" name-generic-aware="java.util.RandomAccess" jni-type="Ljava/util/RandomAccess;" />

@qcjxberin: the quick fix is to just not implement that interface by updating Metadata.xml:

  <remove-node path="//class[@jni-signature='Lcom/alibaba/fastjson/JSONArray;']/implements[@name='java.util.List']" />

E:\Code\DH.Maui.FrameWork\src\DH.Com.Alibaba.Fastjson\obj\Debug\net9.0-android\generated\src\Com.Alibaba.Fastjson.Parser.JSONReaderScanner.cs(266,38): error CS0507: “JSONReaderScanner.CharArrayCompare(char[]?)”: 当重写“protected”继承成 员“JSONLexerBase.CharArrayCompare(char[]?)”时，无法更改访问修饰符

obj/Debug/net9.0-android/generated/src/Com.Alibaba.Fastjson.Parser.JSONReaderScanner.cs(266,38): error CS0507: 'JSONReaderScanner.CharArrayCompare(char[]?)': cannot change access modifiers when overriding 'protected' inherited member 'JSONLexerBase.CharArrayCompare(char[]?)'

The method visibility changed. Use Metadata.xml to change it back by setting visibility, using the comment near the error line for the //attr/@path value:

  <attr path="/api/package[@name='com.alibaba.fastjson.parser']/class[@name='JSONReaderScanner']/method[@name='charArrayCompare' and count(parameter)=1 and parameter[1][@type='char[]']]"
      name="visibility">protected</attr>

There are many similar errors, so if we play "fast and loose" we can fix many at once:

  <attr path="//method[@name='charArrayCompare' or @name='sub_chars'" name="visibility">protected</attr>

obj/Debug/net9.0-android/generated/src/Com.Alibaba.Fastjson.Serializer.FieldSerializer.cs(20,67): error CS0535: 'FieldSerializer' does not implement interface member 'IComparable.CompareTo(Object)'

There are two ways to fix this. Firstly, we can mimic what we did above and just not implement the Comparable interface:

  <remove-node path="/api/package[@name='com.alibaba.fastjson.serializer']/class[@name='FieldSerializer']/implements[@name='java.lang.Comparable']" />

…or you could make use of partial classes to provide the CompareTo(Java.Lang.Object) method, a'la

partial class FieldSerializer {
    public int CompareTo(Java.Lang.Object other) => CompareTo(other.JavaCast<FieldSerializer>());
}

obj/Debug/net9.0-android/generated/src/Com.Alibaba.Fastjson.JSONObject.cs(20,178): error CS0738: 'JSONObject' does not implement interface member 'IMap.EntrySet()'. 'JSONObject.EntrySet()' cannot implement 'IMap.EntrySet()' because it does not have the matching return type of 'ICollection'.

Again, skip the interface:

  <remove-node path="/api/package[@name='com.alibaba.fastjson']/class[@name='JSONObject']/implements[@name='java.util.Map']" />

obj/Debug/net9.0-android/generated/src/Com.Alibaba.Fastjson.Util.FieldInfo.cs(20,61): error CS0535: 'FieldInfo' does not implement interface member 'IComparable.CompareTo(Object)'

We're on a roll! Just skip the type:

  <remove-node path="/api/package[@name='com.alibaba.fastjson.util']/class[@name='FieldInfo']/implements[@name='java.lang.Comparable']" />

---

No errors, lots of warnings:

Metadata.xml:

<metadata>
  <attr path="/api/package[@name='com.alibaba.fastjson.util']/class[@name='AntiCollisionHashMap']/method[@name='entrySet' and count(parameter)=0]"
      name="managedName">_EntrySet</attr>
  <attr path="/api/package[@name='com.alibaba.fastjson.util']/class[@name='AntiCollisionHashMap']/method[@name='entrySet' and count(parameter)=0]"
      name="managedOverride">virtual</attr>
  <remove-node path="//class[@jni-signature='Lcom/alibaba/fastjson/JSONArray;']/implements[@name='java.util.List']" />
  <attr path="//method[@name='charArrayCompare' or @name='sub_chars' or @name='cast']" name="visibility">protected</attr>

  <remove-node path="/api/package[@name='com.alibaba.fastjson.serializer']/class[@name='FieldSerializer' or @name='FieldInfo']/implements[@name='java.lang.Comparable']" />
  <remove-node path="/api/package[@name='com.alibaba.fastjson']/class[@name='JSONObject']/implements[@name='java.util.Map']" />
  <remove-node path="/api/package[@name='com.alibaba.fastjson.util']/class[@name='FieldInfo']/implements[@name='java.lang.Comparable']" />
</metadata>

Additions.cs:

using System.Collections;

namespace Com.Alibaba.Fastjson.Util {
    partial class AntiCollisionHashMap {
        public override ICollection EntrySet() => (ICollection) _EntrySet();
    }
}

I asked:

How is Java.Util.List getting there?

Looks like it is due to "interface alternatives", and we're now looking into getting rid of them from Java Callable Wrappers; see:

• [generator] Place interface alternatives [Register] classes in dummy package. java-interop#1242
• [bindings] Do not [Register] interface alternatives by default. #9196
