how to fetch file from internal storage

Question

my app generates text files and store them in internal storage. there is no problem in reading and writing files but it was throwing exception File not found(no such file or directory ) when i try to send file to laptop using(wlan) ftp.

then after debugging i got that it was a problem of file path. so i hard-coded file path like this

create and write file

 String path=context.getFilesDir().getAbsolutePath();

             File file = new File(path + File.separator + fileName);
             RandomAccessFile rf = new RandomAccessFile(file,"rws"); 
             file.getParentFile().mkdirs();
                Log.d("Created In",path);// in log path i found "/data/data/com.meta.Myapp/files"

                byte[] text = new byte[(int) file.length()];
                rf.readFully(text);
                rf.seek(0);
                rf.writeBytes(data);
                rf.write(text);
                Log.d("write","writing file...");
                rf.close();

client side code to send file

  sock = new Socket("192.168.2.2", 21); 
          // sendfile

                String path="/data/data/com.meta.Myapp/files";

                Log.d("Fetching From",path);

                File myFile = new File ( path+ File.separator + fname); 
                byte [] mybytearray  = new byte [(int)myFile.length()];
                FileInputStream fis = new FileInputStream(myFile);
                BufferedInputStream bis = new BufferedInputStream(fis);
                bis.read(mybytearray,0,mybytearray.length);
                OutputStream os = sock.getOutputStream();
                Log.d("Sending","Sending in progress");
                os.write(mybytearray,0,mybytearray.length);
                os.flush();

              sock.close();

now this is working fine with no problem. but i should not use hardcoded file path. so how to get filepath to fetch file. as client part runs in AsyncTask<> i cant use Context.getFilesDir().getPath() and i dont know how to pass context to AsyncTask<> so how do i solve this problem

no such file or directory means your file or directory is not created or even if it created you may calling it other directory or file which not exist so my advice is first check d file which is generating through your code then chek your calling same file from sharing code? — Android is everything for me, Jul 29 '14 at 08:52
i checked file is created by reading it from another activity — jaimin, Jul 29 '14 at 08:55
you do not have to get path inside AsyncTask, you can get path inside the Activity and then pass it to AsyncTask from which you are sending request to AsyncTask. — Rajen Raiyarela, Aug 07 '14 at 05:58
done .. its working!! if you have answered then i could have marked it as answer — jaimin, Aug 07 '14 at 06:08
