Cara Koneksi database Mysql & PHP dengan Android Eclipse

Cara Koneksi database Mysql & PHP dengan Android Eclipse - Melakukan connect databse Mysql ke Eclipse Android Developer dengan PHP untuk penghubung antara Java dengan Mysql seperti Gambar dibawah ini.

Langsung kita bahas untuk tahapan berikutnya perhatikan baik-baik, jangan skip bacaan bila belum sepenuhnya mengerti dan baca berulang kali

1. buat Project baru Andrid dengan cara FILE > Android Application Project> Application Name "Koneksi" selanjutnya next seusai pengaturan default

2. Hapus Main.XML berada pada folder res > Layout lalu hapus MainActivity.JAVA berada pada folder scr > com.example.koneksi (di hapus karena kali ini tidak membutuhkannya)

3. Buat folder com.example.library pada folder scr , seperti berikut ini struktur foldernya .

4. Setelah folder dibuat lalu dibuat Activity terlebih dahulu, pertama create DashboardActivity.JAVA dengan cara klik kanan pada folder com.example.koneksi > new > class, berikan namnay DashboardActivity dan copy source code berikut ini :

package com.example.koneksi;

import java.util.HashMap;

import org.json.JSONException;

import org.json.JSONObject;

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.util.Log;

import android.view.View;

import android.widget.Button;

import android.widget.EditText;

import android.widget.TextView;

import com.example.library.DatabaseHandler;

import com.example.library.UserFunctions;

public class KoneksiActivity extends Activity {

Button btnLogin;

EditText inputEmail;

EditText inputPassword;

TextView loginErrorMsg;

// JSON Response node names

private static String KEY_SUCCESS = "success";

private static String KEY_ERROR = "error";

private static String KEY_ERROR_MSG = "error_msg";

private static String KEY_UID = "uid";

private static String KEY_NAME = "name";

private static String KEY_EMAIL = "email";

private static String KEY_CREATED_AT = "created_at";

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.koneksi);

// Importing all assets like buttons, text fields

inputEmail = (EditText) findViewById(R.id.loginEmail);

inputPassword = (EditText) findViewById(R.id.loginPassword);

btnLogin = (Button) findViewById(R.id.btnLogin);

loginErrorMsg = (TextView) findViewById(R.id.login_error);

// Login button Click Event

btnLogin.setOnClickListener(new View.OnClickListener() {

public void onClick(View view) {

String email = inputEmail.getText().toString();

String password = inputPassword.getText().toString();

UserFunctions userFunction = new UserFunctions();

Log.d("Button", "Login");

JSONObject json = userFunction.loginUser(email, password);

// check for login response

try {

if (json.getString(KEY_SUCCESS) != null) {

loginErrorMsg.setText("");

String res = json.getString(KEY_SUCCESS);

if(Integer.parseInt(res) == 1){

// user successfully logged in

// Store user details in SQLite Database

DatabaseHandler db = new DatabaseHandler(getApplicationContext());

JSONObject json_user = json.getJSONObject("user");

// Clear all previous data in database

userFunction.logoutUser(getApplicationContext());

db.addUser(json_user.getString(KEY_NAME), json_user.getString(KEY_EMAIL), json.getString(KEY_UID), json_user.getString(KEY_CREATED_AT));

// Launch Dashboard Screen

Intent dashboard = new Intent(getApplicationContext(), DashboardActivity.class);

// Close all views before launching Dashboard

dashboard.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

startActivity(dashboard);

// Close Login Screen

finish();

}else{

// Error in login

loginErrorMsg.setText("Inputkan koneksi yang benar");

}

} catch (JSONException e) {

e.printStackTrace();

}

});

Setelah itu car yang sama buat Class baru dengan nama "KoneksiActivity" lalu copy source code berikut ini "KoneksiActivity.java"
