Android Using AlertDialog Alongside Snackbar -

i'm developing android application deals databases , records. user has option delete record , i'm having trouble deciding how go doing this. options are:

1. use alertdialog pops before record deleted , confirms user's choice delete.
2. use snackbar comes after user deletes, telling them record has been deleted, , giving them option undo.
3. use both alertdialog before deleting (asking confirmation) , snackbar after deleting (with undo action).

i prefer snackbars on alertdialogs don't know if having both best way go. i'm confused correct approach should be. tried looking guidelines or best practices in developer documentation, couldn't find regarding issue. what's best practice in case?
