You are passing the wrong parameters to openFileOutput, the first parameter is the file name not the string which you want to write into file, use this code:

String fileName="SOMEFILENAME.txt";
String str="this is the string you will see inside the file";
            try {
                FileOutputStream outputStream=openFileOutput(fileName,MODE_WORLD_READABLE);
                OutputStreamWriter outputStreamWriter=new OutputStreamWriter(outputStream);
                outputStreamWriter.write(str);
                outputStreamWriter.flush();
                outputStreamWriter.close();
            } catch (FileNotFoundException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO: handle exception
                e.printStackTrace();
            }

Please remove w.flush(); after w.write(str).

since the writing is done not immediately from the buffer but when buffer has sufficient amount of data or is closed. calling flush() on the stream deletes all the data in it whether its written or not.
