入队工作导致奥利奥问题

Question

我有一个myactivity.java类，它像往常一样扩展了AppCompatActivity。我有一个名为HintergrundDienst的前台服务，该服务正在使用HintergrundDienst.enqueueWork(getBaseContext(),HintergrundDienst.class,JI,mServiceIntent);中的myactivity.java执行我要排队的内容。在奥利奥之前，这很好。但是现在，onDestroy中的HintergrundDienst在enqueueWork添加的任务之间被随机调用，然后以一种不可预测的方式继续/重新启动队列。 奥利奥（Oreo）中有什么新原因导致这种情况？我该如何解决？
