How do I read MySQL data from Android using JDBC?

This example show you how to connect and read data from MySQL database directly from Android. The following steps and code snippet will show you how to do it.

Add the MySQL JDBC driver into your project dependencies. Open the app/build.gradle file and add the dependency.


dependencies {
    implementation 'mysql:mysql-connector-java:5.1.49'

If you want to connect to MariaDB you can change the JDBC driver dependency using 'org.mariadb.jdbc:mariadb-java-client:1.8.0', also update the JDBC url in the code snippet by replacing mysql with mariadb.

Next, add internet permission to our application in AndroidManifest.xml file.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android=""

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



Let’s connect, read data from the database and display the information on the screen. In the code snippet we create an AsyncTask to read the information from the database. In the doInBackground() method we open a connection to the database, create a PreparedStatement, execute a query, get a ResultSet and read the information from it. We pack the data into a Map and return it.

After the doInBackground() method finish its execution the onPostExecute() method will be called. In this method we take the result, the Map returned by the doInBackground() method, and set the values into the TextView components for display.


import android.annotation.SuppressLint;
import android.os.AsyncTask;
import android.util.Log;
import android.widget.TextView;
import android.os.Bundle;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.util.HashMap;
import java.util.Map;

public class MainActivity extends AppCompatActivity {
    private static final String URL = "jdbc:mysql://";
    private static final String USER = "kodejava";
    private static final String PASSWORD = "kodejava";

    protected void onCreate(Bundle savedInstanceState) {

        new InfoAsyncTask().execute();

    public class InfoAsyncTask extends AsyncTask<Void, Void, Map<String, String>> {
        protected Map<String, String> doInBackground(Void... voids) {
            Map<String, String> info = new HashMap<>();

            try (Connection connection = DriverManager.getConnection(URL, USER, PASSWORD)) {
                String sql = "SELECT name, address, phone_number FROM school_info LIMIT 1";
                PreparedStatement statement = connection.prepareStatement(sql);
                ResultSet resultSet = statement.executeQuery();
                if ( {
                    info.put("name", resultSet.getString("name"));
                    info.put("address", resultSet.getString("address"));
                    info.put("phone_number", resultSet.getString("phone_number"));
            } catch (Exception e) {
                Log.e("InfoAsyncTask", "Error reading school information", e);

            return info;

        protected void onPostExecute(Map<String, String> result) {
            if (!result.isEmpty()) {
                TextView textViewName = findViewById(;
                TextView textViewAddress = findViewById(;
                TextView textViewPhoneNumber = findViewById(;

  1. Hello Sir,

    I tried your code but got the following message:

    ‘execute(Params…)’ is deprecated as of API 30: Android 11.0 (R)
    ‘android.os.AsyncTask’ is deprecated as of API 30: Android 11.0 (R)

    Overrides deprecated method in ‘android.os.AsyncTask’ as of API 30: Android 11.0 (R)
    I tried to use SDK 30 and getting error:

    :app is currently compiled against android-30.
    Recommended action: Update this project to use a newer compileSdkVersion
    of at least 32, for example 33.

    Any suggestion on what I can do?
    Thank you in advance.

    • Hi Ks, if your MySQL server is running, can you access it from outside of your computer? Do you have any error stack trace that we can see? If I can see your code I might able to test it.

  2. how you get this IP, is it possible with 000webhost or godaddy hosting, how this work, which hosting or what u use.

    • Hi Mayur,

      The IP should be the IP address or domain address of your database server. If you have the public IP address of your hosting like 000webhost or godaddy then you can use it.
