I am using below code for notification builder for receiving notification on android device from through firebase cloud function. I am receiving notification successfully. but The context of the notification is not completely visible as you can see in the image.
On the top left icon is displayed as grey and not showing the actual icon and the text is not shown completely.
How should I rectify the above issues?
Notification Builder
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, ADMIN_CHANNEL_ID)
.setSmallIcon(R.drawable.finalicon)
.setLargeIcon(largeIcon)
.setContentTitle(messageTitle)
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(notificationSoundUri)
.setContentIntent(pendingIntent);
I would kindly suggest you to read NotificationCompat.BigTextStyle.
Helper class for generating large-format notifications that include a lot of text. If the platform does not provide large-format notifications, this method has no effect. The user will always see the normal notification view.
.setStyle(new NotificationCompat.BigTextStyle().bigText("YourText"))
Apply NotificationCompat.BigTextStyle to display text in the expanded content area of the notification. Kindly visit official guide line about Add a large block of text.
FYI
Android uses these values whenever incoming messages do not explicitly set icon or color.
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="@drawable/your_image" />
<!-- Set color used with incoming notification messages. This is used when no color is set for the incoming
notification message. -->
<meta-data
android:name="com.google.firebase.messaging.default_notification_color"
android:resource="@color/colorAccent" />
Read official guideline about Set up a Firebase Cloud Messaging client.
