Read file with Android, what is the expected path?

I am not having luck with this method, which is basically a hello world for printing file contents to the Android cat log.

  try {
            InputStream instream = openFileInput("inputFile.txt");
              InputStreamReader inputreader = new InputStreamReader(instream);
              BufferedReader buffreader = new BufferedReader(inputreader);
              String line;
              while (( line = buffreader.readLine()) != null) {
                System.out.println(line);
              }

          } catch (java.io.FileNotFoundException e) {
            e.printStackTrace();
          }

Using a default generated project with the Android Eclipse plugin, under what directory should this file exist? Any other considerations?

This will try to read the file inputFile.txt from your internal application data directory /data/data/your.application.package/ (and will fail if it doesn't exist):

openFileInput("inputFile.txt");

To read a file from SD card you would do something like this:

new FileInputStream(Environement.getExternalStorageDirectory()
    .getAbsolutePath() + "/inputFile.txt")

Don't forget to set the SD card permission in your manifest then:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

This file should exist in the apps local 'data' directory. Does this file already exist? Have you taken a look at the documentation for file IO on Android?
