android:resource="@mipmap/ic_launcher" />

Where is the problem? I also use this website for creating transparent icon: https://jgilfelt.github.io/AndroidAssetStudio/icons-notification.html#source.space.trim=1&source.space.pad=0&name=ic_stat_ic_launcher

Answer 1

Have you tried changing the manifest line to this:

<meta-data   android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="@drawable/ic_stat_ic_launcher" />

From your screenshots it appears you only have the ic_stat_ic_launcher files in different resolutions.

If you want to use the mipmap/ic_launcher file, you'll need to add the different size files to the other mipmap folders (in the same way you have the mipmap/launcher_icon.png files), otherwise it probably won't find which file to use

Answer 2

The icon to be used for notifications must be white-colored and with transparent background else it will show a grey-colored box.

I had the same problem and resolved it by making changes to the icon image.

Answer 3

In my case, the issue was that I was placing the

<meta-data android:name="com.google.firebase.messaging.default_notification_icon" … />

tag under the main <activity/> tag in the AndroidManifest.xml

Apparently, it should be under the <application/> tag (higher in the hierarchy).
