制作一个APK适用安卓系统APK内容：可以设置关机时间、关机次数、重启次数、自动点击

屏幕等功能的应用。

我们需要使用Android Studio来创建一个新的项目，并添加以下功能：

1. 关机时间设置：用户可以设置指定的时间，应用程序将在该时间自动关机。

2. 关机次数和重启次数设置：用户可以设置关机和重启的次数。当达到指定次数后，应用程序将不再执行关机或重启操作。

3. 自动点击屏幕：应用程序将模拟用户的屏幕点击，以便执行自动化任务。

以下是该应用程序的主要代码：

这是一个简单的应用程序，它允许用户设置关机、重启和自动点击屏幕等功能。请注意，该应用程序需要在rooted的Android设备上运行。
