I have the same code written in Java and in Android to connect to a mysql-server. The same code in Java works, but in android it doesn't.
My Code:
try {
Class.forName("com.mysql.jdbc.Driver");
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
try {
String url1 = "jdbc:mysql://192.168.178.91:3306/db_meinungskanal?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC";
String user = "user1";
String password = "root";
connection = DriverManager.getConnection(url1, user, password);
if (connection != null) {
System.out.println("Connected to the database");
}
} catch (SQLException ex) {
System.out.println("An error occurred. Maybe user/password is invalid");
ex.printStackTrace();
}
In my android app I have granted acces to the internet with permissions, so I'm able to connect to internet. If I run the code in android it doesn't work and I get the following:
System.out: An error occurred. Maybe user/password is invalid 02-11 20:29:13.261 17036-17036/camelgmbh.com.meinungskanal W/System.err: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure 02-11 20:29:13.261 17036-17036/camelgmbh.com.meinungskanal W/System.err: The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
Need help ;D
