Here you can find a clear illustration about how to gain root permissions

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);
    }

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

If I'm getting it right you want to grant your application root privileges. This is not possible with the standard Android image which is installed on the devices. The su command does not support changing to root.

You can however load a customized rooted ROM on your device other than that I'm afraid there is no solution.
