What is a difference between channel ID and channel name in notifications

Question

I tried find what is difference between channel ID and channel name in notifications.

Why NotificationChannel requires two options, why not one option for example just channel id?

Please explain it to me.

Answer 1

From DOCS

setChannelId()

• Specifies the channel the notification should be delivered on.

Channel Name

• The user visible name of the channel. You can rename this channel when the system locale changes by listening for the Intent.ACTION_LOCALE_CHANGED broadcast. The recommended maximum length is 40 characters; the value may be truncated if it is too long
