Here's how to write in a file..

FileOutputStream fos = openFileOutput("urls.txt", Context.MODE_PRIVATE);
fos.write("Alex".getBytes());
fos.close();

Here's how to read that file:

FileInputStream fis = openFileInput("urls.txt");
int c;
while((c=fis.read())!=-1)
        {

            k += (char)c;
        }
fis.close();

String k will contain "Ankit" as a string.

Mind you.. the file "urls.txt" gets formed in the phone memory, you cannot access that file in your project as a resource.

(via google search)

To read a file from internal storage:

  1. Call openFileInput() and pass it the name of the file to read. This returns a FileInputStream.
  2. Read bytes from the file with read().
  3. Then close the stream with close().
