Ok. Berikut tutorial cara mengirim pesan email di android menggunakan Eclipse

1.  Buat project baru, seperti gambar

2.  ketikan kode berikut pada directori "res/layout/activity_main.xml"

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   android:orientation="vertical" >

Tutorial Android SQLite Database

Android menyediakan beberapa cara untuk menyimpan data pengguna dan data aplikasi. Salah satunya ialah dengan menggukanan Database SQLite yang di dukung penuh oleh Android. SQLite adalah database yang sangat ringan yang include dalam Sistem Operasi Android. Dalam tutorial ini saya akan membahas bagaimana menulis class untuk menangani semua operasi SQLite.

Tutorial ini akan menggunakan contoh data penyimpanan buku kontak dalam database SQLite. Dalam membuat database menggunakan method openOrCreateDatabase dengan nama database dan mode sebagai parameter. Dengan mengembalikan instance dari sebuah database SQLite pada sintaks berikut

SQLiteDatabse mydatabase = openOrCreateDatabase("your database name",MODE_PRIVATE,null);

Kita dapat membuat tabel atau memasukkan data ke dalam tabel menggunakan execSQL method didefinisikan dalam kelas SQLiteDatabase. Sintaksnya seperti berikut.

mydatabase.execSQL("CREATE TABLE IF NOT EXISTS TutorialsPoint(Username VARCHAR,Password VARCHAR);");
mydatabase.execSQL("INSERT INTO TutorialsPoint VALUES('admin','admin');");

Untuk mengelola semua aplikasi yang berkaitan dengan database, di buatkan class khusus yang di beri nama SQLiteOpenHelper

public class DBHelper extends SQLiteOpenHelper {
   public DBHelper(){
      super(context,DATABASE_NAME,null,1);
   }
   public void onCreate(SQLiteDatabase db) {}
   public void onUpgrade(SQLiteDatabase database, int oldVersion, int newVersion) {}
}

Ok. Baiklah berikut adalah contoh aplikasi dengan menggunakan database SQLite. Ini adalah aplikasi kontak yang memungkinkan kita untuk menambahkan, menghapus dan memodifikasi kontak. Untuk membuat aplikasi ini, berikut tutorialnya.

1.  Buat Project baru dan atur seperti gambar berikut

2.  Klik  Next  sampai  Finish  dan biarkan default aja.
3.  Masuk ke directory  "res/values/strings.xml"  Sesuaikan dengan kode berikut.

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <string name="app_name">Buku Kontak</string>
    <string name="action_settings">Settings</string>
    <string name="hello_world">Hello world!</string>
    
   <string name="masukkan">Kontak Baru</string>
   <string name="edit">Edit</string>
   <string name="hapus">Hapus</string>
   <string name="title_activity_display_contact">DisplayContact</string>

   <string name="nama">Nama</string>
   <string name="phone">Telp</string>
   <string name="email">Email</string>
   <string name="alamat">Alamat</string>
   <string name="kota">Kota</string>

   <string name="simpan">Simpan</string>

   <string name="hapusKontakYakin">Anda yakin ingin menghapus kontak ini.</string>
   <string name="ya">Ya</string>
   <string name="tidak">Tidak</string>

</resources>

4.  Buat 2 directory baru di "res/menu/" beri nama dengan "display_contact.xml"  dan  "mainmenu.xml"
5.  Buka directory  "res/menu/display_contact.xml"  sesuaikan dengan code berikut.

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
   <item
      android:id="@+id/Edit_Contact"
      android:orderInCategory="100"
      android:title="@string/edit"/>
   <item
      android:id="@+id/Delete_Contact"
      android:orderInCategory="100"
      android:title="@string/hapus"/>

</menu>

6.  Buka directory  "res/menu/mainmenu.xml"  atur codenya seperti berikut

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
   <item android:id="@+id/item1" 
      android:icon="@drawable/ic_launcher"
      android:title="@string/masukkan" 
      android:showAsAction="ifRoom|withText">
   </item>
</menu>

7.  Buka directory  "res/layout/activity_main.xml"  sesuaikan dengan code berikut..

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <ListView
        android:id="@+id/listView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true" >
    </ListView>

</RelativeLayout>

8.  Buat directory baru di  "res/layout"  berinama dengan  "activity_display_contact.xml" lalu sesuaikan dengan code berikut.

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
