Air Native Extension for OS X. Cant call functions from native code.

[Ikol]

Hi, I am trying to build native extension for OS X.

After creating context, I try to call native function with "call" method, but always I have an error "The extension context does not have a method with the name ..."

In as3 code my ExtensionContext is not null, so it's okay. And in native objective-c code I have a function, which I call in as3 code.


What should I do?

Here my code.

Objective-c:

FREContext AirContext = nil;

    FREObject init(FREContext ctx, void* funcData, uint32_t argc, FREObject argv[])
    {
        return nil;
    }

    FREObject someFunction(FREContext ctx, void* funcData, uint32_t argc, FREObject argv[])
    {
        FREDispatchStatusEventAsync(AirContext ,(uint8_t*) "SOME_EVENT", (uint8_t*) "some information" );
        return nil;
    }

    void ANEContextInitializer(void* extData, const uint8_t* ctxType, FREContext ctx, uint32_t* numFunctionsToTest, const FRENamedFunction** functionsToSet)
    {
        NSLog(@"Entering ContextInitinalizer()");
        *numFunctionsToTest = 5;

        FRENamedFunction* func = (FRENamedFunction*) malloc(sizeof(FRENamedFunction) * *numFunctionsToTest);

        func[0].name = (const uint8_t*) "init";
        func[0].functionData = NULL;
        func[0].function = &init;

        func[1].name = (const uint8_t*) "someFunction";
        func[1].functionData = NULL;
        func[1].function = &someFunction

        // other blank functions

        *functionsToSet = func;

        AirContext = ctx;

        FREDispatchStatusEventAsync(AirContext ,(uint8_t*) "SOME_EVENT", (uint8_t*) "some information" );
    }

    void ContextFinalizer(FREContext ctx) {
        NSLog(@"Entering ContextFinalizer()");

        NSLog(@"Exiting ContextFinalizer()");
    }

    void ANEInitializer(void** extDataToSet, FREContextInitializer* ctxInitializerToSet, FREContextFinalizer* ctxFinalizerToSet )
    {

        NSLog(@"Entering ExtInitializer()");

        *extDataToSet = NULL;
        *ctxInitializerToSet = &ContextInitializer;
        *ctxFinalizerToSet = &ContextFinalizer;

        NSLog(@"Exiting ExtInitializer()");
    }

    void ANEFinalizer(void* extData)
    {
        return;
    }

ActionScript3:

public class MyANE extends EventDispatcher{
        private static var _instance:MyANE;

        private var extCtx:ExtensionContext;

        public function MyANE()
        {
            if (!_instance)
            {
                if (this.isSupported)
                {
                    extCtx = ExtensionContext.createExtensionContext("my.awesome.ane", null);
                    if (extCtx != null)
                    {
                        trace('context is okay'); //this trace works
                        extCtx.addEventListener(StatusEvent.STATUS, onStatus);
                    } else
                    {
                        trace('context is null.');
                    }
                }
            _instance = this;
            }
            else
            {
                throw Error('singleton');
            }
        }

    public static function getInstance():MyANE
        {
            return _instance != null ? _instance : new MyANE();
        }

    public function get isSupported():Boolean
        {
            var value:Boolean = Capabilities.manufacturer.indexOf('Macintosh') > -1;
            trace(value ? 'supported' : 'not supported ');
            return value;
        }

    private function onStatus(event:StatusEvent):void
        {
            trace('Event', event, 'code', event.code, 'level', event.level); //this traсе does not works
        }
     private function test(): void
       {
          extCtx.call("someFunction"); //this throws error
       }

XML:

    <extension xmlns="http://ns.adobe.com/air/extension/3.9">
        <id>my.awesome.ane</id>
        <versionNumber>1.0.0</versionNumber>
        <platforms>
            <platform name="MacOS-x86">
                <applicationDeployment>
                    <nativeLibrary>MyANE.framework</nativeLibrary>
                    <initializer>ANEInitializer</initializer>
                    <finalizer>ANEFinalizer</finalizer>
                </applicationDeployment>
            </platform>
        </platforms>
    </extension>

And this script Im using for build ANE:

    mv ../as3/bin/MyANE.swc .
    unzip MyANE.swc
    mv library.swf mac/
    rm catalog.xml
    rsync -a ../Obective-C/ANE/Build/Products/Debug/ANE.framework/ mac/ANE.framework/
    adt -package -target ane MyANE.ane extension.xml -swc MyANE.swc -platform MacOS-x86 -C mac .
    mv MyANE.ane ~/Work/_Projects/test/libs-ane/

I haven't done Objective C in a long time, but if I'm not mistaken, it requires the semicolon to terminate a line of code. The line containing "func[1].function = &someFunction" does not have that termination and since that is the function you are trying to execute, maybe that is the source of the error.

Sorry, I missed it, when edited message. Code is valid (before building ANE, I need to build Objectve-C code, so it's checked for validity)

Hey, Even i am facing the same issue but for Android platform.
