How to Establish a Connection Between Android and MySQL using the MySQL JDBC Driver?

Establishing Connectivity between Android and MySQL using MySQL JDBC Driver

Connecting an Android application with MySQL using the MySQL JDBC driver can sometimes lead to challenges. To provide assistance, we will offer guidance on successfully setting up this connection.

Using the MySQL JDBC Driver

To connect with MySQL from Android, follow these steps:

1. Acquire the mysql-connector-java-3.0.17-ga-bin.jar driver from the official MySQL website.
2. Save the downloaded JAR file in the libs directory of your Android project.
3. Configure the build path of the project by adding the JAR file.
4. Grant INTERNET permission in the AndroidManifest.xml for accessing the MySQL server.

Code for Connection:

After integrating the driver, use the following code to establish a connection:

try{
    Class.forName("com.mysql.jdbc.Driver").newInstance();
}catch(Exception e){
    System.err.println("Cannot create connection");
}
try{
    connection = DriverManager.getConnection("jdbc:mysql://192.168.xx.xx:3306/dbname","root","password");
    Statement statement = connection.createStatement();

    String query = "SELECT column1, column2 FROM table1 WHERE column3 = ";
    query = query +"'" +variable+"'";           
    ResultSet result = statement.executeQuery(query);
}catch(Exception e){
    System.err.println("Error");
}

Additional Tips:

• If errors occur during driver initialization or connection establishment, consider removing the Target SDK version from the manifest, as it may cause issues with certain versions.
• To retrieve data from a remote MySQL server, ensure that the server is accessible from the Android device.
