1、API介绍

以下是ShellUtils中最终执行命令的方法execCommand：

Java

public CommandResult execCommand(String[] commands, boolean isRoot, boolean isNeedResultMsg)

其中commands表示依次执行的shell命令数组

isRoot表示是否以su用户执行(需要手机已经root)

isNeedResultMsg表示是否存储命令执行成功及失败后的信息。

Java

/**

* result of command

*

* @author Trinea 2013-5-16

*/

public static class CommandResult {

/** result of command **/

public int result;

/** success message of command result **/

public String successMsg;

/** error message of command result **/

public String errorMsg;

public CommandResult(int result){

this.result = result;

}

public CommandResult(int result, String successMsg, String errorMsg){

this.result = result;

this.successMsg = successMsg;

this.errorMsg = errorMsg;

}

}

CommandResult 为返回的数据结构，如下其中result表示执行的结果，根据linux命令执行规则，0表示成功，其他为相应错误码。

successMsg存储执行成功后的输出信息，errorMsg存储执行失败后的输出信息。

如果isNeedResultMsg为false，successMsg和errorMsg会始终为空，而result依然为正常结果。

其他接口，Shell命令支持执行String(单个命令), List(多个命令)，String[](多个命令)

见：ShellUtils.java#Api Guide

使用

以目前自己的几个场景举下例子

(1) 拷贝文件

原理是adb执行命令：

mount -o rw,remount /system

cp /mnt/sdcard/xx.apk /system/app/

Java代码如下：

String[] commands = new String[] { "mount -o rw,remount /system", "cp /mnt/sdcard/xx.apk /system/app/" };

CommandResult result = ShellUtils.execCommand(commands, true);

注意一般拷贝文件是不需要root的，上面用root是因为需要拷贝到/system/app/下面

(2) 静默安装和卸载

这个很多朋友已经用过了Android root权限静默安装或卸载应用，原理是执行命令：pm install apkFilePath及pm uninstall packageName

具体代码可见：PackageUtils installSilent(Context context, String filePath, String pmParams)

(3) Android修改hosts文件

原理是执行命令：

mount -o rw,remount /system

echo “127.0.0.1 localhost” > /etc/hosts

echo “185.31.17.184 github.global.ssl.fastly.net” >> /etc/hosts

chmod 644 /etc/hosts

代码如下：

Java

List commnandList = new ArrayList();

commnandList.add("mount -o rw,remount /system");

commnandList.add("echo \"127.0.0.1 localhost\" > /etc/hosts");

commnandList.add("echo \"185.31.17.184 github.global.ssl.fastly.net\" >> /etc/hosts");

commnandList.add("chmod 644 /etc/hosts");

CommandResult result = ShellUtils.execCommand(commnandList, true);

用echo命令改hosts文件很牛逼哦，不用重启可以直接生效的哦。
