Where should Android App data be stored? How should I write to a file?

Where should the CSV output text file from my Android App (writing in Eclipse) be stored. I currently use:

> File peopledetail_file = new File(this.getFilesDir(),
> "PeopleDetailsFile");

and 

InputStream filestream = openFileInput("PeopleDetailsFile");

to access my file. This clearly does not work, as I get an error, saying it can't be found at this location

/data/data/com.example.partyorganiser/files/PeopleDetailsFile

For Creating a file you must call peopledetail_file.createNewFile() then write your file 

File peopledetail_file = new File(this.getFilesDir(), "PeopleDetailsFile");
peopledetail_file.createNewFile();
FileOutputStream fos = new FileOutputStream(peopledetail_file);
// do writing ...
PrintWriter pw = new PrintWriter(fos);
pw.print("Hello");
pw.flush
fos.flush();
fos.close();

If you are going to use openFileInput(), use openFileOutput().

If you are going to use getFilesDir() for output, use getFilesDir() for input.
