Facebook emang lagi boomingnya sekarang. Apa-apa di connectin sama facebook. Kayak Foursquare dan lain-lain juga bisa di tampilin di FB. Mungkin karena facebook sudah merajalela sampe ke pelosok desa kali ya makanya apa-apa di connectin ke FB. Sekalian bisa sebagai fasilitas buat ngiklanin product juga. Oke qt mau nyoba bagaimana develope aplikasi di android agar bisa terkoneksi ke Facebook.

1. Download Facebook Connect Android

Bisa di dapetin di sini. Kita bisa dapetin bentuk .zip dari link tadi. Silahkan di unzip “fbconnect-android.zip/api”  dan jadiin API ini menjadi .Jar dengan cara :

• Buka Eclipse

• File->Import->Existing Project into Workspace. Abis itu tujuan kita menjadi API ini menjadi  .Jar .

• File->Export->JAVA->Jar File . Masukan nama yg di inginkan untuk membuat .Jar . Atau kalau gak mau ribet. Ane kasih Link nya aja : Silahkan download di sini

2. Tambahkan FBConnect.Jar kedalam project

3. Membuat Applikasi di Facebook

Sebelum memulai coding kita harus membuat aplikasi terlebih dahulu. Aplikasi ini nantinya akan di panggil di android kita dengan cara memasukan KEY dan SECRET. Cara membuat aplikasi di facebook dengan mengakse http://www.facebook.com/developers kemudian klik Set Up New Application teruskan langkahnya sampai aplikasi kita terdaftar di facebook dengan hasil akhir mendapatkan Secret & Key dari aplikasi tersebut.

4. Masukan kode beikut sebagai XML

Misal namanya facebook_android.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:layout_width="wrap_content" android:layout_height="wrap_content">
	<com.codecarpet.fbconnect.FBLoginButton
		android:id="@+id/login" android:layout_width="fill_parent"
		android:layout_height="wrap_content" />

	<TextView android:id="@+id/label"
		android:layout_width="fill_parent" android:layout_height="wrap_content"/>

	<Button android:id="@+id/feedButton" android:layout_width="fill_parent"
		android:layout_height="wrap_content" android:text="Publish to Feed"
	/>
</LinearLayout>

Dan untuk class Activitesnya :
