Notification Counter - Android Studio Tutorial | Part 1

thank you for this tutorial!
i have a question: how to add a badge if the app receives an FCM data type notification? (and the app stat is in the background or killed)

Thank You

The 50dp in app:cardCornerRadius="50dp" is overkill. 9dp will suffice.

Hy can you help me

the card to display number is not displaying color

great work

I have a question is there any other way to add notification counter badge in the imageview? or this is the only way?

Can i ask you two more questions. I had design my application for church liturgy on PlayStore but i don't have any database. I wrote all of them on strings.

1. How can i insert the (liturgy) "words" In to database. ?
2. How to display notifications when there is a new the liturgy or information for user.

Where should i start. Please kindly give you're link or tutorial video related to my questions.

Plz.. make a video on add to cart
