RemoteServiceException for Android 9 and Android 10

[vsay01]

It's working fine for Android 8 but error with Android 9 and Android 10.

Fatal Exception: android.app.RemoteServiceException: Bad notification for startForeground: java.lang.RuntimeException: invalid channel for service notification: Notification(channel=null pri=0 contentView=null vibrate=null sound=null tick defaults=0x0 flags=0x60 color=0x00000000 vis=SECRET internalType=0 internalPriority=0 internalGroupPriority=0 internalFlag=0)

Anyone find solutions for this ?

I resolved this by create channel before create notification in getPersistentNotification(int id) of StandOutWindow class.
