Hi all..
Most of our visitors had problem with one of our previous post on Android-php connection. So here I am posting another simple example to connect with a php file. Here I am simply putting an echo in the php file which ehoes back the data from the android side.
Here are the things you need to remember.
1. Make sure your server is running(Xampp or Wampp).
2. Make sure you give right path of your php file inside your android program.
3. Make sure you have put the internet permission in the android manifest file.
4. And the last one the android side and php side posting variables should be the same.Here is the android main java file contents.
package pack.coderzheaven;

import org.apache.http.message.BasicNameValuePair;

import android.os.Bundle;
import android.view.View;

public class AndroidPHPConnectionDemo extends Activity {
Button b;

HttpPost httppost;
StringBuffer buffer;

List<NameValuePair> nameValuePairs;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
b = (Button)findViewById(R.id.Button01);
et= (EditText)findViewById(R.id.EditText01);
tv= (TextView)findViewById(R.id.tv);
b.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
final ProgressDialog p = new ProgressDialog(v.getContext()).show(v.getContext(),"Waiting for Server", "Accessing Server");
Thread thread = new Thread()
{
@Override
public void run() {
try{
httpclient=new DefaultHttpClient();
httppost= new HttpPost("http://10.0.0.2/my_folder_inside_htdocs/connection.php"); // make sure the url is correct.
//add your data
nameValuePairs = new ArrayList<NameValuePair>(1);
// Always use the same variable name for posting i.e the android side variable name and php side variable name should be similar,
nameValuePairs.add(new BasicNameValuePair("Edittext_value",et.getText().toString().trim())); // $Edittext_value = $_POST['Edittext_value'];
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
//Execute HTTP Post Request
response=httpclient.execute(httppost);
ResponseHandler<String> responseHandler = new BasicResponseHandler();
final String response = httpclient.execute(httppost, responseHandler);
System.out.println("Response : " + response);
runOnUiThread(new Runnable() {
public void run() {
p.dismiss();
tv.setText("Response from PHP : " + response);
}
});
}catch(Exception e){
runOnUiThread(new Runnable() {
public void run() {
p.dismiss();
}
});
System.out.println("Exception : " + e.getMessage());
}
}
};
thread.start();
}
});
}
}
Here is the main.xml the layout for the above file.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<EditText
android:text=""
android:id="@+id/EditText01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:singleLine="true">
</EditText>
<Button
android:text="Send to php side"
android:id="@+id/Button01"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</Button>
<TextView
android:id="@+id/tv"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text=""
/>
</LinearLayout>
Here is the android manifest.xml file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="pack.coderzheaven"
android:versionCode="1"
android:versionName="1.0">
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".AndroidPHPConnectionDemo"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Here is the PHP side. I am simply echoing back the value send from the android side.
connection.php
$val = $_POST['Edittext_value']; echo $val;
here I have a Edittext on my android side and after entering something in it and hitting the button to send, the textbox data will be send to the server and the server echoes back the same data.
My php file is saved in a folder named “my_folder_inside_htdocs” and named “connection.php”
I am working in localhost so it is given as “10.0.2.2″ please replace your domain name here.
However you have a MySQl-connection in that php file and fetch some data from the database and echo back from the php side. You will get that data as string in the php side in this line
ResponseHandler<String> responseHandler = new BasicResponseHandler();
String response = httpclient.execute(httppost, responseHandler);
System.out.println("Response : " + response); </blockquote>
You can manipulate this string as you want.

Here is another more detailed explanation.
How to create Simple Login form using php in android? – Connect php with android.
First create a database named “mydatabase” in MySql. Then create a table “tbl_user” with three fields (id, username and password).
The next step is to create a php page which will communicate between the MySql database and the android application.
For this create a “Connections.php” page as shown below. It will set up a connection to the database with the username and password
$hostname_localhost ="localhost"; $database_localhost ="mydatabase"; $username_localhost ="root"; $password_localhost =""; $localhost = mysql_connect($hostname_localhost,$username_localhost,$password_localhost) or trigger_error(mysql_error(),E_USER_ERROR);
Then the main PHP file is to be created. Actually the android application will call this php file along with the data(username and password ) and this code will check the database. If the details is valid then it will return “Y” and otherwise return “N”.
Here the data is passed as POST method. We can also use GET method where the data is passed along with the url . Android support both these two features.
<?php require_once('yourfolder/Connections.php'); mysql_select_db($database_localhost,$localhost);
$useremail = $_POST['UserEmail'];
$password = $_POST['Password'];
$query_search = "select * from tbl_user where username = '".$useremail."' AND password = '".$password. "'";
$query_exec = mysql_query($query_search) or die(mysql_error());
$rows = mysql_num_rows($query_exec);
if($rows --> 0) { echo "Y"; }
else {echo "N"; }
So by now we created php and the database part. Then we have to focus on android section. For this first create a xml file which will be our login screen.The screen look like this.
The layout of the xml is displayed below.
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ff2a1703"
android:fadingEdge="horizontal">
<TextView
android:id="@+id/text"
android:text="manage your projects..."
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:typeface="serif"
android:textStyle="italic"
android:layout_centerHorizontal="true"
android:layout_alignParentTop="true"
android:layout_marginTop="50dip"
android:textSize="20sp" >
</TextView>
<EditText
android:id="@+id/username"
android:layout_width="213dip"
android:layout_marginTop="60dp"
android:layout_below ="@+id/text"
android:layout_centerHorizontal="true"
android:layout_height="wrap_content"
android:hint="username"
android:gravity="center"
android:textSize="18sp"
android:typeface="sans"
android:textStyle="italic">
</EditText>
<EditText
android:id="@+id/password"
android:layout_width="211px"
android:layout_height="wrap_content"
android:hint="password"
android:textSize="18sp"
android:typeface="sans"
android:textStyle="italic"
android:gravity="center"
android:password="true"
android:layout_marginTop="20dp"
android:layout_below ="@+id/username"
android:layout_centerHorizontal="true">
</EditText>
<CheckBox
android:id="@+id/check"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Remember me"
android:layout_marginTop="10dp"
android:layout_below ="@+id/password"
android:layout_centerHorizontal="true">
</CheckBox>
<Button
android:id="@+id/login"
android:layout_width="141px"
android:layout_height="wrap_content"
android:text="Login"
android:textSize="22sp"
android:typeface="serif"
android:textStyle="bold"
android:layout_marginTop="20dp"
android:layout_below ="@+id/check"
android:layout_centerHorizontal="true">
</Button>
</RelativeLayout>
We now create the java file . This file should contain the 3 sections
1. Store the preference when the checkbox is checked
2. Establish a connection between this file and the php file
3. Validate the user
