Youtube App not closing when video is finised Amazon firetv

I'm building an application that plays launches youtube videos. I'm able to launch a youtube application and video. But the problem is when the video is finished youtube app is not closed itself also, my main app also goes in the background.

    @Overridepublic void configureFlutterEngine(@NonNull FlutterEngine flutterEngine) {    super.configureFlutterEngine(flutterEngine);    new MethodChannel(flutterEngine.getDartExecutor().getBinaryMessenger(), CHANNEL)            .setMethodCallHandler(                    (call, result) -> {                        if (call.method.equals("playVideoInNativeYoutubePlayer")) {                            System.out.println(call.argument("videoId").toString());                            Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.youtube.com/watch?v=" + call.argument("videoId").toString()));                            intent.putExtra("force_fullscreen", true);                            intent.putExtra("finish_on_ended", true);                            startActivity(intent);                        } else {                            result.notImplemented();                        }                    }            );}

I'm using the flutter method channel to call this method from my flutter application.I have read every post available on the internet. But no one has a solution for this.
