login from android app

Hi
I want to login to database using android app with a login page
and now i want to know how can i hash password and salt from login page to database user table

This might help:

https://github.com/traccar/traccar/blob/master/src/org/traccar/helper/Hashing.java

But I would recommend to use API and not database directly.

ok thanks
and now how can i enter the account username and pass in andriod app???
when I'm using api it ask me the user and pass
how I can I enter these is android???

Solved!
thank you
