Question

Since I am using card view my minimim sdk is for adroid Lollipop and I know from Lollipop you have to use transparent icon for notification bar

I have created a transparent notification icon (32x32) and stored it in drawable

But whenever I am sending the notification I am seeing a white circle instead of my icon

Answer 1

将图标参数添加到通知有效内容中。

Answer 2

我建议您使用android assets generator生成通知图标，然后下载并将所有图标放在res目录中。 同时从您的通知服务提供商（FCM，OneSignal等）发送相同的图标名称，它将像魅力一样工作。
