Hey Expo,
I was going through Configuration with app.json
and would like to clear up some icon questions. I’d love to update the docs afterwards too!
App Icon:
https://docs.expo.io/versions/latest/guides/configuration.html#icon
Local path or remote url to an image to use for your app’s icon. We recommend that you use a 512x512 png file with transparency. This icon will appear on the home screen and within the Expo app.
-
Assuming with iOS 11 this should now be 1024x1024 png. For iOS, what happens to the transparency? Is it filled in with white?
-
Should the icons we upload all have a pixel density of @4x especially with iPhone X & android’s insane screen resolutions?
Notification Icon:
https://docs.expo.io/versions/latest/guides/configuration.html#icon-1
Local path or remote url to an image to use as the icon for push notifications. 48x48 png grayscale with transparency.
But assets/icon/notification-icon.png
is 144x144 and RGB with transparency. Is this the new recommended format & size?
Loading Icon:
https://docs.expo.io/versions/latest/guides/configuration.html#icon-2
Local path or remote url to an image to display while starting up the app. Image size and aspect ratio are up to you. Must be a .png.
Can we offer a recommended width, height or aspect ratio? What if somebody uses their 1024x1024 app icon here? Or something that looks poopy?
Thanks!
