I can connect via another app , but not with mine (just to say my server works fine).
Class.forName("com.mysql.jdbc.Driver").newInstance()
conn = DriverManager.getConnection(
"jdbc:mysql://*.*.*.*:3306/Biblioteca",
connectionProps)
I have the driver mysql-connector-j-8.0.31.jar ,I'm using android studio. I've searched a lot of tutorials and everyone can connect with this, but i can't.
