收到推送后点击跳转到指定页面后，无法回调到onMessage方法中

可以收到离线推送，点击后可以跳转到继承UmengNotifyClickActivity的指定页面，但是只执行到了onCreate方法，无法回调到onMessage方法中，内容如下：

private val mNotificationClick = object : UmengNotifyClick() {
override fun onMessage(msg: UMessage?) {
msg?.let {
runOnUiThread {
val body = it.raw.toString()
parseBody(body)
}
}
}
}

override fun onCreate(p0: Bundle?) {
super.onCreate(p0)
mNotificationClick.onCreate(this, intent)
}

override fun onNewIntent(p0: Intent?) {
super.onNewIntent(p0)
mNotificationClick.onNewIntent(p0)
}

Logcat中有推送sdk打印的日志：
