How to Connect Android Applications to MySQL using JDBC Driver?

Connecting Android Applications to MySQL with MySQL JDBC Driver

Establishing connectivity between Android applications and MySQL databases can be a challenging task. This article provides a detailed guide to assist developers in successfully connecting their Android projects to MySQL using the MySQL JDBC driver.

The first step involves downloading the necessary JDBC driver (mysql-connector-java-3.0.17-ga-bin.jar) and adding it to the project's libs folder. Next, configure the project's build path to include the added JAR file.

To allow the application to establish network connections, AndroidManifest.xml should be modified to include the INTERNET permission. The following code snippet provides a sample connection configuration:

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");
}

In some cases, removing the Target SDK version from the manifest can resolve connection issues. It is essential to ensure that the Target SDK version is compatible with the JDBC driver being used.

Alternative methods for connecting to MySQL from Android projects include using the MySQL Connector/J library, implementing a RESTful web service, or utilizing a third-party cloud solution.
