你怎么运行的Andr​​oid应用程序内的shell脚本？ [英] How do you run a shell script inside of an Android app?

问题描述

我想写的root用户一个Android应用程序，运行一系列shell命令或shell脚本，如果这是preferable，并显示输出......任何人都可以点我在正确的方向？

I am trying to write an android app for root users that runs a series of shell commands, or a shell script if that is preferable, and displays the output... can anyone point me in the right direction?

推荐答案

这个片段需要root访问权限，但将执行给定String作为一个shell命令

This snippet requires root access, but will execute the given String as a shell command

void execCommandLine(String command)
{
    Runtime runtime = Runtime.getRuntime();
    Process proc = null;
    OutputStreamWriter osw = null;

    try
    {
        proc = runtime.exec("su");
        osw = new OutputStreamWriter(proc.getOutputStream());
        osw.write(command);
        osw.flush();
        osw.close();
    }
    catch (IOException ex)
    {
        Log.e("execCommandLine()", "Command resulted in an IO Exception: " + command);
        return;
    }
    finally
    {
        if (osw != null)
        {
            try
            {
                osw.close();
            }
            catch (IOException e){}
        }
    }

    try 
    {
        proc.waitFor();
    }
    catch (InterruptedException e){}

    if (proc.exitValue() != 0)
    {
        Log.e("execCommandLine()", "Command returned error: " + command + "\n  Exit code: " + proc.exitValue());
    }
}
