  Hi everyone,

  I am trying to save data to my google phone G1. I am able to create
  the text file in sdcard by using the following code in eclipse :

  //++
  try {
                  FileWriter f = new FileWriter(/sdcard/test.txt);
          } catch (IOException e) {
                  // TODO Auto-generated catch block
                  e.printStackTrace();
          }
  //+

  but I am not able to save any data to the created file. I found this
  code from http://www.anddev.org/working_with_files-t115.html; which
  says I can write to text file by running this code.

  //+++
  try { // catches IOException below
            final String TESTSTRING = new String(hello);

            FileOutputStream fOut = openFileOutput(/sdcard/test.txt,

  MODE_WORLD_READABLE);
            OutputStreamWriter osw = new OutputStreamWriter(fOut);

            // Write the string to the file
            osw.write(TESTSTRING);
            // ensure that everything is
            // really written out and close
            osw.flush();
            osw.close();

        } catch (IOException ioe) {
            ioe.printStackTrace();
       }
  //+

  I run it but I do not see any change in my file.
  first, I thought my problem is permission to file. The permission
  setting on my phone is:

  data        :   drwxrwx--x
  sdcard    :   d---rwxrwx
  system    :   drwxr-xr-x

  would you please help me in either in correcting the code or finding a
  way to save data into text file (saved in sdcard or the phone) in
  eclipse environment

  thanks in advance

Context.openFileOutput() opens a private file associated with this
Context's application package for writing and the name of the file to
open can not contain path separators.

Try this:
