问题 My app icon on the notification tray became white on android 5. I have seen this Notification bar icon turns white in Android 5 Lollipop , but how can I change it on my codenameone app. 回答1: It is possible to place a 24x24 icon named "ic_stat_notify.png" under the src/ folder of the app. The icon can be white with transparency areas.
