write private file to internal storage

I trying to write some files on the internal storage.

I saw theFileOutputStream fos = openFileOutput(FILENAME, Context.MODE_PRIVATE); on Data Storage and I understood that the file will be private to my application.

but the problem is it can only open a file without a path, so first I opened a new directory file with file.mkdir(), but now, how do I write the file as private ?

If you call Context.openFileOutput() the file will always be written into your application's data directory (i.e. "/data/data/appname/filename"). You cannot use sub folders here! The documentation for this function says

nameThe name of the file to open; can not contain path separators.

Correct. They will be private by default.

but the problem is it can only open a file without a path, so first I opened a new directory file with file.mkdir(), but now, how do I write the file as private ?

Your files that you create in subdirectories off of in getFilesDir() are private by default -- you do not have to do anything special to make them be private.
