我一直在尝试检测用户何时在他/她的设备上启动应用程序。

所以我找到了这个解决方案：

https://stackoverflow.com/a/7239840/833219

我在线程中添加了这段代码。所以我的应用程序每 3 毫秒获取一次日志，但我找不到日志之间的区别，所以我无法检测到用户应用程序启动的代码是什么。

这是我添加此行时得到的日志示例：

String w = log.toString();
Log.i("LockService","w ="+w);

使用此代码，我如何检测到用户启动了应用程序？

阅读日志是一个可怕的想法，并且在系统的各个版本之间也存在问题。实际上，您可以在此处注册一个广播意图：ACTION_PACKAGE_FIRST_LAUNCH但是，请注意，这仅在 API 级别 12+ 中可用。

ActivityManager您可以使用日志中的标签检测应用程序启动。

在日志中您可以找到有用的数据。您可以检测运行包。

例如 ：

06-06 16:09:06.007: I/ActivityManager(1663): Starting: Intent { act=android.intent.action.MAIN flg=0x10840000 cmp=com.android.phone/.InCallScreen } from pid -1

它是com.android.phone包装并InCallScreen从第一页开始。

您可以检查包名称并检测目标应用程序何时启动。
