Android Question Securely erase a file

[Rusty]

Is there a way to "securely" erase a file on the android similarly to the Windows BCWipe?
I need to delete data and over write it so that it can never be "un-erased" or used.
(HIPPA requirements)
Thanks

A simple erase can be recovered as you know by many different programs. Not sure if this is what you want but.

You could overwrite the file in code prior to its deletion with "fake content". So if it was recovered the data would be worthless. You could also look at the encryption library , so if recovered it would have to be decrypted.

Hope his helps.
