Answer 1

Your file is written on the device's internal storage. By default, files saved to the internal storage are private to your application and other applications cannot access them (nor can the user). When the user uninstalls your application, these files are removed.

If you want to browse for the saved file on the phone storage, you have to write it on external storage (sd card, or build in storage). Here's an example how to write/read from external storage: Android how to use Environment.getExternalStorageDirectory()

Answer 2

The parameter file is the path where your file located.

but sometimes you can't see it in your phone storage because of the permission.

You can open DDMS-File Explorer, Then when you tracking the path there is a 'Permissions' column where you can see if you have full access to a folder or a file.
