Application-private data storage location can be queried by
Context.getFilesDir.
Alternatively, one can use Context.getFileStreamPath or
Context.openFileOutput.
These APIs are there for a reason, so it's good idea to use them.
BTW, application- and user- specific storage locations have been
changing in Windows, as well. First we had "C:\Documents and settings",
now it's "C:\Users", etc. There are APIs to get these locations as well.

Linda,
I am new to Android. I had my app on a Microsoft phone and used .txt
files for data storage. It seemed like a good idea on the Microsoft
smartphone and it worked.
I did the same with my app on the Android and found that unexpected
things happen with text files on the Android. Things like the path to
the sdcard changed with versions and also with different devices, i.e.
AT&T androids have two sdcards and there are little complications. I
am not saying that Android cannot handle txt files. My thinking is
that on Android data storage is "designed" to work with sqlite
database.
(I like the Android development environment much better than
Microsoft!)
I converted my data storage to utilize sqlite database. My impression
is that everything works smoother (with my app) when I use sqlite
database. I can make it work with .txt files but it seems like that is
like paddling upstream. And paddling downstream is better.

Hello to all,
I wrote a file o the phone from my application in the following path:
/data/data/<my_project_name>/files/my_file.txt
If i run the application in emulator, i can see my file created in
this path.
but if i run the application on a real device, i can't see this file.
Using DDMS from the eclipse the "data" folder from the phone has
permissions drwxrwx--x - what does this mean?
and when i try to expend the "+data" , it seems to be empty.
I use the "Astro" programm to access the "data" folder from the phone,
and it seems to be empty.
Is the content hidden of this folder, and there is not a way to see
what it contains?
Thanks
Lidia
