我正在尝试运行

String command = "su -c 'busybox ls /data'";
p = Runtime.getRuntime().exec(command);

在我的应用程序中,但似乎语法有点错误。不过,我从手机上的终端模拟器应用程序运行它没有问题,所以我只是不明白为什么从我的应用程序中调用它时它不起作用。

任何帮助都深表感谢!

找到解决方案!感谢onit here建议的链接。请参见下面的代码:要使超级用户 shell 命令正常工作,您首先需要创建一个超级用户 shell 并将其分配给进程,然后分别对其输入和输出流进行写入和读取。

Process p = Runtime.getRuntime().exec(new String[]{"su", "-c", "system/bin/sh"});
DataOutputStream stdin = new DataOutputStream(p.getOutputStream());
//from here all commands are executed with su permissions
stdin.writeBytes("ls /data\n"); // \n executes the command
InputStream stdout = p.getInputStream();
byte[] buffer = new byte[BUFF_LEN];
int read;
String out = new String();
//read method will wait forever if there is nothing in the stream
//so we need to read it in another way than while((read=stdout.read(buffer))>0)
while(true){
    read = stdout.read(buffer);
    out += new String(buffer, 0, read);
    if(read<BUFF_LEN){
        //we have read everything
        break;
    }
}
//do something with the output

使用以下功能:

public void shellCommandRunAsRoot(String Command)
{
 try 
  {
     Process RunProcess= Runtime.getRuntime().exec("su");
     DataOutputStream os;
     os = new DataOutputStream(RunProcess.getOutputStream()); 

     os.writeBytes(cmds+"\n");
         os.writeBytes("exit+\n");
     os.flush();

  }
  catch (IOException e)
  {
     // Handle Exception 
  }    
}

用法:

shellCommandRunAsRoot("pkill firefox");
