Connecting Android to MySQL with Mysql JDBC Driver

Connecting an Android project to a MySQL database using the Mysql JDBC driver can be a straightforward process. Here's a comprehensive guide on how to establish the connection:

1. Obtain the JDBC Driver:

   • Download the appropriate version of the mysql-connector-java JAR file (e.g., mysql-connector-java-3.0.17-ga-bin.jar).

2. Add the Driver to Your Android Project:

   • Copy the JAR file into the "libs" folder within your Android project.
   • Right-click on the JAR file and select "Configure Build Path" > "Add to Build Path."

3. Grant INTERNET Permission:

   • Open the AndroidManifest.xml file for your project.

   • Add the following line within the element:

     <uses-permission android:name="android.permission.INTERNET" />

4. Establish the Connection:

   • Use the following code snippet to connect to your MySQL database:

     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");
     }

5. Tips:

   • If you encounter connection errors, try removing the Target SDK version from your manifest, as it can sometimes cause issues with drivers.

By following these steps, you can easily establish a connection between your Android project and a MySQL database using the Mysql JDBC driver.
