java - how to List the mounted files in local directory programmatically? -


i'm mounting network using samba sharing. after mounting when open , see file browser network files shown in mounted folder. when call directory.listfiles(); it's failing show files programmatically.

this code...

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){}

after when check /data/test directory files shown... when call 

  file directory = new file("/data/test/");   file[] fileslist = directory.listfiles();

it's not showing exception , crashing app.. log details are...
