推荐答案

如果该设备是植根，你可以使用下面的code，以获得一个root shell：

If the device is rooted, you can use the following code to gain access to a root shell:

    try
    {
        Process process = Runtime.getRuntime().exec("su");
        DataOutputStream outputStream = new DataOutputStream(process.getOutputStream()); 
        DataInputStream inputStream = new DataInputStream(process.getInputStream());

        outputStream.writeBytes(command + "\n");
        outputStream.flush();

        outputStream.writeBytes("exit\n"); 
        outputStream.flush(); 
        process.waitFor();
    }
    catch (IOException e)
    {
        throw new Exception(e);
    }
    catch (InterruptedException e)
    {
        throw new Exception(e);
    }

在哪里命令是要执行的命令。

Where "command" is the command that you want to execute.
