Error: adaptive icons with no fallback drawable for FCM notifications, can cause irreversible crash on Android Oreo

Question

今天开发 Android 应用程序时，我在 logcat 中收到以下错误消息：

You are targeting Android Oreo and using adaptive icons without having a fallback drawable set for FCM notifications. This can cause a irreversible crash on devices using Oreo. To learn more about this issue check: https://issuetracker.google.com/issues/68716460

我花了一段时间才弄清楚意思和做什么，所以我在下面添加一个答案。

这是 Pusher Beams Android SDK warning about a bug in Android 8.0 Oreo. See this article for more information about it. Also, check out 生成的错误。

如上述链接和 here in the documentation 中所述，要解决该问题，请将以下 meta-data 添加到您的 AndroidManifest：

<manifest ...>
    <application...>

        <meta-data
            android:name="com.google.firebase.messaging.default_notification_icon"
            android:resource="@drawable/ic_default_notification" />
       <meta-data
            android:name="com.google.firebase.messaging.default_notification_color"
            android:resource="@color/colorAccent" />

    </application>
</manifest>

其中 ic_default_notification 是您自己创建的内容。要在 Android Studio 中制作，请右键单击 drawable 文件夹并选择 New > Image Asset。对于图标类型，选择通知图标。
