I've got a strange problem with notification icon today.
It looks like this : (the white circle ...)
Did I do something bad ?
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.icon_notification)
.setContentTitle(this.getString(R.string.notification_title))
.setContentText(this.getString(R.string.notification_text))
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
Here is my icon image (freshly downloaded from here https://material.io/icons/#ic_photo ) : http://image.noelshack.com/fichiers/2016/44/1478185219-icon-notification.png
Did I miss something ?
For the record, I'm using SDK 24 and only created the hdpi
resource folder for now.
Edit #1 : I've added the ldpi
, mdpi
and xhdpi
icons, nothing change ...
Edit #2 : For more precision, I'm trying to create this notification from a service ... FCM messaging service ...
If your compileSDKversion is above 20 then notification icon should be a white-on-transparent background image. Otherwise the image will be rendered as a white colored image.
Please go through the below link too for guidelines to create the icon
https://www.google.com/design/spec/patterns/notifications.html
and also the notification icon generator.
It seems to be a problem of cache during compilation ... The first image I was using was bad (fully colored), so I think my compilator created somekind of cache on the filename.
I work on Windows and did this : uninstall the app from my phone, invalidate all cache from Android sudio => at re-compilation, the icon was OK.
U need to have separate icon generated which will be white version of your launcher icon. U can use below link to generate such icon.
Note : You need to upload PNG image of your launcher icon with transparent background.
For setting icon u can have a method like this
private int getSmallIconForNotification(){
return (Build.VERSION.SDK_INT>Build.VERSION_CODES.LOLLIPOP)? R.mipmap.ic_stat_launcher : R.mipmap.ic_launcher;
}
Code usage:
private NotificationCompat.Builder createNotificationBuilder(){
return new NotificationCompat.Builder(this)
.setSmallIcon(getSmallIconForNotification())
.setContentTitle("New Message")
.setContentText("Hi there.....")
.setAutoCancel(true);
}
Note:- If device has android version above 20 you have to generate icon with transparent background and while generating notification use this snippet
int currentapiVersion = android.os.Build.VERSION.SDK_INT;
if (currentapiVersion >= android.os.Build.VERSION_CODES.LOLLIPOP){
currentapiVersion=R.mipmap.ic_notification_lolipop;
} else{
currentapiVersion=R.mipmap.ic_launcher;
}
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(currentapiVersion)......
I had the same problem while the app is closed and this helped me
Unfortunately this was a limitation of Firebase Notifications in SDK 9.0.0-9.6.1. When the app is in the background the launcher icon is use from the manifest (with the requisite Android tinting) for messages sent from the console.
With SDK 9.8.0 however, you can override the default! In your AndroidManifest.xml you can set the following fields to customise the icon and color:
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="@drawable/notification_icon" />
<meta-data android:name="com.google.firebase.messaging.default_notification_color"
android:resource="@color/google_blue" />
