我有一个应用程序应该使用一些shell命令将文件从SD卡复制到/ system/media /.它将需要root,我正在root设备上进行测试.我正在使用运行时来执行shell命令,但它不起作用.这是我的运行时间

public void RunAsRoot{String[] commands = {"sysrw", "rm /data/local/bootanimation.zip", "sysro"};{
    Process p = Runtime.getRuntime().exec("su");
    DataOutputStream os = new DataOutputStream(p.getOutputStream());            
    for (String tmpCmd : commands) {
    os.writeBytes(tmpCmd+"\n");
    }           
    os.writeBytes("exit\n");  
    os.flush();
}

但我的logcat只显示其中两个没有被拒绝
