为什么我的通知图标在Oreo中无法正确显示? [英] Why is my notification icon not displayed properly in Oreo?

问题描述

很长一段时间以来，我们的应用程序中都有通知，这些通知都可以正常运行.我有一个供他们使用的彩色的小.png图标，过去效果很好.

We have notifications in our app since a long time, which work fine. I have a small, multicoloured .png-icon we use for them, that have worked fine in the past.

在奥利奥(Oreo)中，图标显示不正确，只是一个灰色方块.看着设备上的抽屉，看来系统，gmail等现在都是单色的.图标，所以我怀疑这与它有关.

In Oreo, the icon is not displayed properly, it is just a grey square. Looking at the drawer on the device, it seems that the system, gmail etc. all now have single-colour icons, so i suspect that it has something to do with that.

但是，我找不到任何文档，设计指南或任何可证实这一点的东西，所以我在这里投降了一个问题...

However, i can't find any documentation, design guidelines or anything that confirm this, so i am surrendering to a question here...

如何在Oreo中正常显示图标?我想念什么?

How can i make my icon display as normal in Oreo? What am i missing?

这是我创建图标的方式，根据我在文档中看到的内容，它应该可以工作，并且可以在Oreo之前运行:

This is how i create the icon, from what i can see in documentation it should work, and it works pre-Oreo:

NotificationCompat.Builder builder = new NotificationCompat.Builder(context);

builder.setAutoCancel(true).setContentTitle("Title").setWhen(when)
.setContentText(message).setDefaults(Notification.DEFAULT_ALL)
.setSmallIcon("icon.png").setContentIntent(contentIntent);

getNotificationManager(context).notify(NOTIFICATION_ID, builder.build());
