Private jdbcUrl As String = "jdbc:mysql://localhost/petrosoft"
localhost means you’re trying to access the database running on your phone. Pretty sure that’s not what you are intending to do

I don´t believe that there is a MYSQL-Server running on your Phone!

Where exactly is the MySQL-Server running?

No sir, MYSQL Server not running on phone, but how to run MYSQ in phone i don't know, it is required to run in phone ?
You are not able to run mysql on the phone.

The MySQL must run on a Server/VPS to then connect to it using jdbcsql.

The suggested solution is to use jRDC2 on your Server/VPS and connect to the MySQL-Server from within the jRDC2-Server.
You Phoneapp connect to your jRDC2 Server then.
