Is this double salt hashing scheme strong enough?

Question

Android

Applications on android:
The user logs in and the following password data is sent to the server
(hash (hash password) + (something taken from the password hash as a salt))
On the server:
Getting this hash and doing the following:
(hash ((hash (hash came in the request)) + (hash (salt that is in the database)))
Well, I check what happened with what is in the database
. As a result, a salt is obtained that is not stored anywhere and in order to crack the password, you will need to find out the salt generation algorithm android application. Is it all right? Or is there a hole somewhere

Answer 1

Security through obscurity is the worst option. Transmit the password over a secure connection and don't be perverted.
And the hole is that if someone can intercept the password, then he can intercept the cache with the same success, this will be enough for authentication.

Answer 2

There is no point in this - send the password itself via https and that's it.

Answer 3

the algorithm for obtaining salt in the android application, if desired, can be found.
