Pertama kita download dahulu Facebook Android SDK dari link berikut
Kemudian extract dan Import ke Eclipse, caranya klik File-Import, Existing Projects into Workspace, kemudian pilih facebook-android-sdk.
Langkah berikutnya kita generate KeyHash atau Application Signature dari Project kita dengan buat memakai keytool yang telah tersedia dari JDK yang sudah terinstall di komputer Anda. kemudian ditambah software OpenSSL yang dapat didownload di link berikut.
Buka command DOS prompt, klik Start-Run, ketik perintah berikut :
<lokasi jdk>\bin\keytool.exe -exportcert keystore | <lokasi program openSSL>\bin\openssl.exe sha1 -binary | <lokasi program openSSL>\bin\openssl.exe base64
Enter keystore password : android
Kemudian setelah mendapatkan key yang diinginkan catat, simpan baik-baik untuk dimasukkan ke Facebook Application Developer Setting.
Setelah itu login terlebih dahulu ke Facebook untuk mendaftarkan aplikasi yang akan dibuat, klik link berikut untuk masuk ke Facebook Application Developer.
Daftarkan sebuah aplikasi yang akan kita buat, pilih bertipe Android Application. Kemudian masukkan Hash Key yang tadi dapatkan.
Kemudian didapatkan App ID, catat dan simpan baik-baik untuk dipakai di kode program pada Project Android.
Buat project baru di Eclipse. Kemudian klik Project-Properties, pilih Tab Android, Library klik Add. Pilih com_facebook_sdk.
Pada MainActivity kita panggil dan gunakan Facebook SDK dengan Kode Program berikut :

Kemudian untuk tampilan kita pakai layout default dari main.xml ditambah tiga button seperti ini :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#f0f0f0">
<!-- Facebook Login Button -->
<Button android:id="@+id/btn_fblogin"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="30dip"
android:layout_gravity="center_horizontal"
android:text="Login with Facebook"/>
<!-- Facebook Post to Wall Button -->
<Button android:id="@+id/btn_fb_post_to_wall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Post to Wall"
android:layout_marginTop="30dip"
android:layout_gravity="center_horizontal"
android:visibility="gone"/>
<!-- Facebook Logout Button -->
<Button android:id="@+id/btn_get_profile"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Get Profile Data"
android:layout_marginTop="30dip"
android:layout_gravity="center_horizontal"
android:visibility="gone"/>
<!-- Button to show access tokens -->
<Button android:id="@+id/btn_show_access_tokens"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Show Access Tokens"
android:layout_marginTop="30dip"
android:layout_gravity="center_horizontal"
android:visibility="gone"/>
</LinearLayout>
Jangan lupa memberi permission INTERNET pada AndroidManifest.xml agar dapat terhubung ke Server Facebook :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.amijaya.androidfacebookapplication"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".MainActivity"
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>
<uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.INTERNET"/>
</manifest>
Hasilnya, kita bisa mengupdate Status Facebook via Android Application :
