By default, the notification's text content is truncated to fit one line. If you want your notification to be longer, for example, to create a larger text area, you can do it in this way:

A. var builder = NotificationCompat.Builder(this, CHANNEL_ID) .setContentText("Much longer text that cannot fit one line...") .setStyle(NotificationCompat.BigTextStyle() .bigText("Much longer text that cannot fit one line...")) ...
B. var builder = NotificationCompat.Builder(this, CHANNEL_ID) .setContentText("Much longer text that cannot fit one line...") .setLongText("Much longer text that cannot fit one line...")) ...
C. var builder = NotificationCompat.Builder(this, CHANNEL_ID) .setContentText("Much longer text that cannot fit one line...") .setTheme(android.R.style.Theme_LongText); ...
