Tutorial Android dan MySQL dengan PHP

1. Pastikan telah menginstal ADT Bundle/Android Studio dan Xampp
2. Mengakses PhpMyAdmin di browser -> localhost/xampp/phpmyadmin
3. Buat Database di PhpMyAdmin dengan nama -> "android"
4. Buat Tabel di database android dengan nama -> "pengguna", buat kolom username, dan password
5. Buat folder baru di C:/xampp/htdocs/ dengan nama -> Android
6. Ketiikan kode PHP dibawah ini untuk menyimpan data, bisa menggunakan editor notepad dan simpan dengan nama save.php


<?php
$conn = mysql_connect("localhost","root","");
mysql_select_db("android");

$username=$_POST['username'];
$password=$_POST['password'];

$query="insert into pengguna values('$username','$password')";
$result=mysql_query($query);
?>

7. Buat project baru di eclipse dengan nama AndroidMySQL
8. Buat tampilan berikut :

9. Buat kelas ConnectHttpClient.java
package com.wim.androidmysql2;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URI;
import java.util.ArrayList;

import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.conn.params.ConnManagerParams;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.params.HttpConnectionParams;
import org.apache.http.params.HttpParams;

public class ConnectHttpClient {
public static final int HTTP_TIMEOUT = 30 * 1000; // milliseconds

public static HttpClient mHttpClient;

//return an HttpClient object with connection parameters set
private static HttpClient getHttpClient() {
if (mHttpClient == null) {
mHttpClient = new DefaultHttpClient();
final HttpParams params = mHttpClient.getParams();
HttpConnectionParams.setConnectionTimeout(params, HTTP_TIMEOUT);
HttpConnectionParams.setSoTimeout(params, HTTP_TIMEOUT);
ConnManagerParams.setTimeout(params, HTTP_TIMEOUT);
}
return mHttpClient;
}

public static String executeHttpPost(String url, ArrayList<NameValuePair> postParameters) throws Exception {
BufferedReader in = null;
try {
HttpClient client = getHttpClient();
HttpPost request = new HttpPost(url);
UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(postParameters);
request.setEntity(formEntity);
HttpResponse response = client.execute(request);
in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));


StringBuffer sb = new StringBuffer("");
String line = "";
String NL = System.getProperty("line.separator");
while ((line = in.readLine()) != null) {
sb.append(line + NL);
}
in.close();

String result = sb.toString();
return result;
} finally {
if (in != null) {
try {
in.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}

public static String executeHttpGet(String url) throws Exception {
BufferedReader in = null;
try {
HttpClient client = getHttpClient();
HttpGet request = new HttpGet();
request.setURI(new URI(url));
HttpResponse response = client.execute(request);
in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

StringBuffer sb = new StringBuffer("");
String line = "";
String NL = System.getProperty("line.separator");
while ((line = in.readLine()) != null) {
sb.append(line + NL);
}
in.close();

String result = sb.toString();
return result;
} finally {
if (in != null) {
try {
in.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}

}

10. Tambahkan kode berikut di MainActivity.java
package com.wim.androidmysql2;

import java.util.ArrayList;

import org.apache.http.NameValuePair;
import org.apache.http.message.BasicNameValuePair;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

public class MainActivity extends Activity {

TextView error;
EditText txusername, txpassword;
Button simpan;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

txusername = (EditText) findViewById(R.id.editText1);
txpassword = (EditText) findViewById(R.id.editText2);
error = (TextView) findViewById(R.id.textView3);
simpan = (Button) findViewById(R.id.button1);

simpan.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
// TODO Auto-generated method stub

ArrayList<NameValuePair> postParameter = new ArrayList<NameValuePair>();
postParameter.add((new BasicNameValuePair("username", txusername.getText().toString())));
postParameter.add((new BasicNameValuePair("password", txpassword.getText().toString())));

String response = null;

try{
response = ConnectHttpClient.executeHttpPost("http://10.0.2.2/Android/save.php", postParameter);

String res = response.toString();
res = res.trim();
res = res.replaceAll("\\s+","");

if (res.equals("1")){
error.setText("Gagal");
}else{
error.setText("Sukses");
}
}catch(Exception e){
e.printStackTrace();
}
}
});
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}

}

11. Tambahkan permission di AndroidManifest.xml
















12. Selesai, tinggal di run

Semoga bermanfaat
Happy Coding :)
