How to receive OAuth callback

ianxm

Hello. I'm new to Feathers UI and OpenFL. I am trying to implement an OAuth2 flow with Feather UI but can't see how to receive the callback. I expect I need to set a BROWSABLE intent filter in the AndroidManifest and then the main Activty will receve an onResume() when the callback is received, but Feathers UI's base is Application which doesn't expose those event handlers. Is there a way to get them?

I see Lime has them in GameActivity and it passes calls down to extensions. Do I need to create an extension? If so, does the Application have to poll the extension to get the result?

Thanks

Android Activities are at a lower level than OpenFL's Haxe layer, so yes, you'll probably need to create an extension of to access the lower-level APIs and expose them to OpenFL/Haxe. I'm not sure if polling is the best way or not, though.

Thanks, that worked. Also you were right that polling wasn't needed.

Posting some snippits here in case someone else has the same question and finds this.

application:

class HelloWorld extends Application {
#if android
    private static var setCallbackHandler = JNI.createStaticMethod(
        "org.haxe.extension.CallbackListener",
        "setCallbackHandler",
        "(Lorg/haxe/lime/HaxeObject;)V"
    );
#end

    private function someAction( event :TriggerEvent ) {
#if android
        setCallbackHandler(this);
#end
        lime.system.System.openURL('$OAUTH_ENDPOINT?redirect_uri=...');
    }

    public function resumeAuth( code :String ){
        // ... complete oauth flow
    }
}

extension:

public class CallbackListener extends Extension {

    static HaxeObject callbackHandler;

    public static void setCallbackHandler(HaxeObject callbackHandler) {
        CallbackListener.callbackHandler = callbackHandler;
    }

    public void onNewIntent (Intent newIntent) {
        mainActivity.setIntent(newIntent);
    }

    public void onResume () {
        Uri uri = mainActivity.getIntent().getData();
        if( uri != null && "https".equals(uri.getScheme()) && callbackHandler != null ){
            callbackHandler.call1("resumeAuth", uri.toString());
        }
    }
}
