Java BroadcastReceiver在后台OREO+；
在我的应用程序中有两个接收器，一个接收呼叫（Java BroadcastReceiver在后台OREO+；,java,android,Java,Android,在我的应用程序中有两个接收器，一个接收呼叫（MyReceiverCall），另一个接收短信（MyReceiverSms）。 当你启动应用程序时，一切正常，我收到短信或电话时会收到通知。 但是，如果我在task Manager中关闭应用程序，则没有任何功能可用，所有传入的短信和呼叫都会被接收器忽略。 我有一个假设，可以简单地用我的通知服务不启动，但通过日志我了解到，接收器根本不工作。（但到目前为止，我们的假设是服务业应该受到责备） 我的代码 MyReceiverCall.class public

我认为这是预期的行为（当你杀死应用程序时）。我可以想象，出于安全原因，它是有帮助的。@ror但是，即使应用程序被终止，您如何使接收器工作，否则，处理传入短信和呼叫的应用程序如何工作
