Question

我正在使用samba共享安装网络。打开后安装并查看文件浏览器后，网络文件显示在已安装的文件夹中。但是当我调用directory.listFiles();时，它无法以编程方式显示文件。

这是我的代码......

Main.java;

String mountFilePath1 = "//10.0.0.18/BeagleBoneBlack/JackSongs";
try{
            Process su = Runtime.getRuntime().exec("su");
            DataOutputStream outputStream = new DataOutputStream(su.getOutputStream());
            outputStream.writeBytes("umount /data/test/ \n  chmod -R 777  /data/test/ \n mount -t cifs -o user=root,pass=guest,nounix,noserverino " + mountFilePath1 + "   /data/test/\n");
            outputStream.flush();
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }catch(IOException e){}

此后我检查/ data / test目录文件显示...但是当我打电话

  File directory = new file("/data/test/");
  File[] filesList = directory.listFiles();

它没有显示任何异常并导致应用程序崩溃.. 日志详细信息是......
