Firebase Notification Always shows blank icon
Solution 1
This is the default behaviour of FCM. When app is in background it will take white icon.
Use this tag and put it in your Manifest. For me this worked. Hope it works for you too. Ensure meta-data is inside application like the example mentioned in quickstart
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme"
tools:ignore="GoogleAppIndexingWarning">
<!-- [START fcm_default_icon] -->
<!-- Set custom default icon. This is used when no icon is set for incoming notification messages. -->
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="@drawable/ic_stat_ic_notification" />
<!-- 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" />
<!-- [END fcm_default_icon] -->
<!-- [START fcm_default_channel] -->
<meta-data
android:name="com.google.firebase.messaging.default_notification_channel_id"
android:value="@string/default_notification_channel_id" />
<!-- [END fcm_default_channel] -->
<activity
android:name=".EntryChoiceActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".kotlin.MainActivity" />
<activity android:name=".java.MainActivity" />

If you are having this problem
See this link: Icon not displaying in notification: white square shown instead
I had the same problem. I solved by making transparent image from designer. Make sure your logo should be 72*72 pixels.
NOTE: Don't time waste in googling this issue, you just need a transparent icon which should be 72*72 dimensions.

The only thing that worked for me was to generate a Notification icon image asset in Android studio. To use the an image as the notification icon, just set Asset type to "Image" and select the file.
Tip #1: use an icon which is of white color, on transparent background!
Tip #2: if the preview on the right side of the window contains only white squares, your notification icon will look just like that - white squares!
Tip #3: the Name of the asset is what should be added into the meta-data
tag in AndroidManifest
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="@drawable/whatever_you_set_for_image_asset_name" />

Keep your notification small as 72 x 72 and make it completely white. See the photo attached with this answer.
Then paste the codes below into your manifest.
<meta-data android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="@drawable/ic_stat_money" />
You can make a new icon from default icons pack of Android Studio.
For this right click on your drawable folder > New > Image Asset

I faced same problem and did everything suggested here and nothing worked.
Eventually, downgrading the firebase plugin from 11.8.0 to 11.6.0 resolves it with the help of this github issue.
This might also help someone.

Mahdi almost 2 years
I'm new with FCM. I cannot make FCM use my app icon as notification icon and the icon is always a white blank one.
I imported an icon to
mipmap
folders but nothing seems changed. As some dude say that this is because of lollipop notification as in this questionBut the problem is, the FCM notification automatically pops up and I cannot get the Notification builder to override the icon. How can I change it?

Mahdi over 7 yearsthanks i saw the link. but where should I implement Notification builder. cause in FCB android pop notification automatically.
-
Mahdi over 7 yearsI up voted you because it was part of my answer. but I can not replace FCM auto generated notification icon.

Däñish Shärmà over 7 yearsactually fcm is totally different from gcm. There are two types of notifications in fcm. You have to study about it. This is the very good documentation github.com/codepath/android_guides/wiki/Google-Cloud-Messaging . One more thing in fcm if your app is in background, notifications won't hit onMessageReceived(). For this you need to do server side coding. from server the response should be like, check this link stackoverflow.com/questions/37358462/… , see(Ankit Adlakha) answer

encastellano almost 7 yearsIts the only way that i found for how correct icon. Its a firebase bug for showing notifications in background mode. Firebase pick default app icon instead your definition on your notification builder.
