Android ShellUtils手机管理器

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

javascript 复制代码

public void ShutDown(View view) {
   ShellUtils.execCommand("reboot -p", true);
}

（2）重启

javascript 复制代码

public void Reboot(View view) {
   ShellUtils.execCommand("reboot", true);
}

（3）快速重启

javascript 复制代码

public void FastReboot(View view) {
     ShellUtils.execCommand("busybox killall system_server", true);
}

（4）进入刷机模式

javascript 复制代码

public void Recovery(View view) {
    ShellUtils.execCommand("reboot recovery", true);
}

（5）进入引导模式

javascript 复制代码

public void FastBoot(View view) {
    ShellUtils.execCommand("reboot bootloader", true);
}
