SMS BroadcastReceiver在一段时间后停止工作 [英] SMS BroadcastReceiver stops working after sometime

问题描述

我有一个应用程序，一旦收到短信，它就会执行一些任务。我已经使用BroadcastReceiver实现了它。安装该应用程序后，它会在一段时间内正常工作。

I have an app which does some task once it receives a SMS. I have implemented it using BroadcastReceiver. After installing the app, it works fine for sometime.

此后，我注意到BroadcastReceiver的onReceive事件未触发。为了进行故障排除，我重新启动了我的应用程序服务，并将移动设备连接到Android Studio Logcat。如前所述，最初它检测到新的SMS，并且一切正常。 30分钟后我发送短信时，未触发onReceive事件。在Logcat的30分钟内，没有与我的应用相关的消息。

Afterwards, I notice that onReceive event of BroadcastReceiver is not triggered. To troubleshoot, I restarted my app service and connected the mobile to Android Studio Logcat. As earlier, initially it detected new SMS and everything worked fine. When I sent SMS after 30 mins, onReceive event was not triggered. There was no messages related to my app during that 30 mins in Logcat.

看起来像BroadcastReceiver服务被杀死了。可能是什么原因。我该如何解决？我正在Android 8.1中测试此应用。

Looks like BroadcastReceiver service is killed. What could be the reason. How can I troubleshoot? I am testing this app in Android 8.1.

推荐答案

问题是EMUI，MIUI等正在杀死后台任务。将应用列入白名单后，现在可以正常使用了。

The issue was the the EMUI, MIUI etc were killing the background tasks. After whitelisting the app, it works fine now.
