尝试接收Android API级别低于26的OneSignal通知时发生异常

onesignal notifications android

今天我注意到我的应用程序在Oreo之前的设备(API级别低于26)上停止接收来自OneSignal的通知。在尝试调试时,我注意到当我应该收到通知时会抛出这个异常。

有时不会抛出异常(尤其是在使用模拟器时),但通知仍然不会显示

我用的是一个信号 3.10.6 带有定制NotificationExtender服务的gradle实现。( 你知道这是什么原因吗?最近我更改了我们的项目proguard规则,但即使禁用了proguard,错误仍然存在。

编辑问题似乎出在 通知扩展服务 。当我禁用CustomNotificationExtender服务并添加NotificationReceivedHandler时,通知开始到达,但是,我无法切换到NotificationReceivedHandler,因为我仍然需要能够选择要向用户显示的通知,以及显示为警报或仅显示为通知的通知。
