main中的致命异常

Question

我是入门级开发人员，我试图创建一个用于在SIM卡之间进行切换的脚本，并且我输入了adb shell service call之类的命令，现在没有识别出SIM卡，并且手机一直在重启。logcat显示以下崩溃日志（com.android.phone上的致命异常被重复了大约6到7次，但是出于明显的原因，我只是将它们删减了。）

Answer 1

前一段时间，我们决定不让用户知道就不能在后台运行服务。

在API >= 26中，您需要作为前台启动服务（只要该服务可操作，便会向用户显示即时通知-例如：音乐播放器等。

您将找到更多信息here。

您也可以看到此implementation example

希望这会有所帮助。
