Run the application and choose a running android device and install the application on it and verify the results. Modify AndroidManifest.xml to add necessary permissions. Modify res/values/string.xml file and add necessary string components. Modify layout XML file res/layout/activity_main.xml add any GUI component if required.

Modify src/MainActivity.java file to add Activity code.Ĭreate src/SiginActivity.java file to add PHPMYSQL code. You will use Android studio IDE to create an Android application and name it as PHPMYSQL under a package. To experiment with this example, you need to run this on an actual device on which wifi internet is connected. The php page has been given below which takes parameters by post method. The table has only one record which is ("admin","admin","administrator"). In that database, a table has been created with the name of table1. In this example a database with the name of temp has been created at. It creates a basic application that allows you to login using GET and POST method. The below example is a complete example of connecting your android application with MYSQL database via PHP page. InputStreamReader(conn.getInputStream())) OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream()) īufferedReader reader = new BufferedReader(new After writing, you need to open stream to receive the responded data. The last thing you need to do is to write this data to the link. URLConnection conn = url.openConnection() + "=" + URLEncoder.encode(password, "UTF-8")

+ "=" + URLEncoder.encode(username, "UTF-8") ĭata += "&" + URLEncoder.encode("password", "UTF-8") String data = URLEncoder.encode("username", "UTF-8") The urlencoder will encode the information of the passing variables. In the Post method, the URLEncoder, URLConnection class will be used. (new InputStreamReader(response.getEntity().getContent())) HttpResponse response = client.execute(request) After that you need to open streams to receive the data. HttpClient client = new DefaultHttpClient() Īfter that you need to call execute method of HttpClient class and receive it in a HttpResponse object. We will use HttpGet and HttpClient class to connect. There are two ways to connect to MYSQL via PHP page. Android - Connecting MYSQL Connecting Via Get Method In Post method, the variables are not passed through URL. The only change in the above script is to replace $_GET with $_POST. The variables are passed in the url and the record is fetched. The first method to pass information is through GET method in which $_GET command is used. In order to fetch record some information must be passed to PHP page regarding what record to be fetched. PHP is also used to fetch the record from the mysql database once it is created. The Insert Into statement creates the database. Now its time to insert some data into the tables.

When the database and tables are created. The CREATE TABLE statement creates the database. Once database is created, its time to create some tables in the database. The CREATE DATABASE statement creates the database. MYSQL database can be created easily using this simple script. Our application will communicate with the PHP page with necessary parameters and PHP will contact MYSQL database and will fetch the result and return the results to us. MYSQL is used as a database at the webserver and PHP is used to fetch data from the database. This is very useful in case you have a webserver, and you want to access its data on your android application. In this chapter, we are going to explain, how you can integrate PHP and MYSQL with your android application.
