Missing MediaManager debugging messages on receiver

Question

After load is completed, i try to send the new status to the sender (an Android app). I try the following:

mediaManager.broadcastStatus(true, '', {media}, true);
mediaManager.sendStatus(senderId, requestId, true, {media}, true);
mediaManager.sendLoadComplete(media);

When I run my code, I have nothing related to this in the debugger. I was expecting a message from cast_receiver.js like: 'sending message' or an error but I just get nothing.

Even when I use: mediaManager.onMetadataLoadedOrig(media), i catch nothing, how can I know that I am sending something to the sender? Should I add a specific code?

I am expecting something like: Unexpected connected message for already connected sender

I am really new at this.

Thanks for your help.
