1. Android ShellUtils手机管理器
Android Shell工具类，可用于检查系统root权限，并在shell或root用户下执行shell命令。如：
checkRootPermission() 检查root权限 。execCommand(String[] commands, boolean isRoot, boolean isNeedResultMsg) shell 环境执行命令，第二个参数表示是否root权限执行 execCommand(String command, boolean isRoot) shell环境执行命令。

1.2. 使用
（1）关机
public void ShutDown(View view) {
ShellUtils.execCommand("reboot -p", true);
}
（2）重启
public void Reboot(View view) {
ShellUtils.execCommand("reboot", true);
}
（3）快速重启
public void FastReboot(View view) {
ShellUtils.execCommand("busybox killall system_server", true);
}
（4）进入刷机模式
public void Recovery(View view) {
ShellUtils.execCommand("reboot recovery", true);
}
（5）进入引导模式
public void FastBoot(View view) {
ShellUtils.execCommand("reboot bootloader", true);
}

利用命令“adb shell input keyevent <键值>”可以实现自动化。例如“adb shell input keyevent 3”就可以按下Home键。]
（1）执行返回：adb shell input keyevent 4
（2）执行灭屏亮屏：adb shell input keyevent 26
（3）执行解锁屏幕：adb shell input keyevent 82
