Recurring Messages when using Toast with an Intent Service

I am working on displaying an Android Toast message from an IntentService. After a bit of research and understanding how Loopers, Handlers and Message queues work, I implemented the solution found here: Toast on an IntentService

I find that in addition to the latest toast, the previous toast messages are displayed in order. Can anyone explain what is happening and how to resolve this?

private static void toast(final Context context, final String message, final int duration){
    Handler handler = new Handler(Looper.getMainLooper());
    handler.post(new Runnable() {
        @Override
        public void run() {
            Toast toastMsg = Toast.makeText(context, message , duration);
        }
    });

}

thank you, I have added the implementation – Spindoctor Feb 20 '17 at 00:49
perhaps make Toast toastMsg as global (outside of the function toast) and check if toast is not null you can call toastMsg.cancel() before showing a new toast message – vims liu Feb 20 '17 at 01:39
unfortunately, that too did not work. BTW the code is related to Udacity's StockHawk project: https://github.com/udacity/StockHawk. – Spindoctor Feb 21 '17 at 16:18

you are not calling `show()` on toast anywhere – arjun Feb 24 '17 at 12:26
Thank you for pointing that out. I did not show that in the code but I am. Thanks. – Spindoctor Feb 28 '17 at 16:50
