I am attempting to write a file to external storage in android. I keep getting the error, "java.io.FileNotFoundException: /mnt/sdcard/Survey.txt (Is a directory)." The method that contains the code for this is as follows: 

```
public String sendFile(System system) throws FileNotFoundException {

    File writeable = new File(Environment.getExternalStorageDirectory()
            .getAbsolutePath() + "/Survey.txt");
    try {
        writeable.createNewFile();
    } catch (IOException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }

    try {

        Log.w("Before FO", "***");
        if (!Environment.getExternalStorageState().equals(
                Environment.MEDIA_MOUNTED)) {
            Toast.makeText(context, "External SD card not mounted",
                    Toast.LENGTH_LONG).show();
        } else {
            FileOutputStream f = new FileOutputStream(writeable);
            Log.w("before write", "0");

            f.write("HELLOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO".getBytes());
            Log.w("before write", "1");
            f.close();
        }
    } catch (Exception e) {
        Log.w("Write sd", e.toString());
    }

    return writeable.getAbsolutePath();
}

```

I believe the program is crashing on the FileOutputStream deceleration, because Log.w("Before FO", "*\**"); executes. I have been searching for an answer to this problem for several day, so any help will be greatly appreciated. Thanks!
