Image Issues?
For troubleshooting, see Notification Images Not Showing.
Sliding Image on Android (too many notifications in tray)
When there are too many notifications in the tray, your image may not be shown at first. The notification has to be "scrolled down" to see the image:
Badge
Chrome on Android
For Chrome 53+ on Android 6.0+, the badge replaces the Chrome browser icon that appears on the notification tray and above the title. In this example, a custom badge for the app replaces the Chrome browser icon:
Badge Requirements
| Color |
Not supported: RGB channels. Badges use alpha channels because they must appear on both light and dark backgrounds. |
| Resolution | 72x72 or larger |
| Filetype |
Not supported: Must use an HTTPS URL |
Here's an example badge icon of our OneSignal logo that uses only the alpha channel.
