This tutorial is about integrating facebook into your android application. I am going to explain various steps like generating your application signature, registering facebook application, downloading facebook sdk and other steps. Here is an official documentation of facebook integration.
Generating App Signature for Facebook Settings
To create facebook android native app you need to provide your Android application signature in facebook app settings. You can generate your application signature (keyhash) using keytool that comes with java. But to generate signature you need openssl installed on your pc. If you don’t have one download openssl from here and set it in your system environment path.
Open your command prompt (CMD) and run the following command to generate your keyhash. While generating hashkey it should ask you password. Give password as android. If it don’t ask for password your keystore path is incorrect.
keytool -exportcert -alias androiddebugkey -keystore "<path-to-users-directory>\.android\debug.keystore" | openssl sha1 -binary | openssl base64
check the following command how i generated hashkey on my pc.
keytool -exportcert -alias androiddebugkey -keystore "C:\Users\Ravi\.android\debug.keystore" | openssl sha1 -binary | openssl base64
Registering your Facebook Application
After generating your app signature successfully, register your facebook application by going to create new facebook application and fill out all the information needed. And select Native Android App and give your hashkey there which you generated previously using keytool.
and note down your facebook App ID
Creating Facebook Reference Project
Once you are done with registering your facebook application, you need to download facebook SDK and create a new reference project. This reference project will be used to compile your actual project.
1. Download facebook android SDK from git repositories.
(git clone git://github.com/facebook/facebook-android-sdk.git)
2. In your Eclipse goto File ⇒ Import ⇒ Existing Projects into Workspace and select the facebook project you downloaded from git repository.
Creating Your Facebook Connect Project
1. Create new Project in your Eclipse IDE. File ⇒ New ⇒ Android Project and fill out all the details.
2. Now we need to add reference of this project to existing facebook project. Right Click on Project ⇒ Properties ⇒ android ⇒ Click on Add button ⇒ select your facebook project ⇒ Click Apply.
Now our project setup is done. We can start coding our facebook application.
3. Open your AndroidManifest.xml file add network connect permission in order to connect to internet.
<uses-permission android:name="android.permission.INTERNET"/>
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.facebook.androidhive" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" /> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" > <activity android:label="@string/app_name" android:name=".AndroidFacebookConnectActivity" > <intent-filter > <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <!-- Connect to Internet Permissions --> <uses-permission android:name="android.permission.INTERNET"/> </manifest>
4. Open Your Main Activity Class and initialize all the variables needed.
public class AndroidFacebookConnectActivity extends Activity { // Your Facebook APP ID private static String APP_ID = "308180782571605"; // Replace your App ID here // Instance of Facebook Class private Facebook facebook; private AsyncFacebookRunner mAsyncRunner; String FILENAME = "AndroidSSO_data"; private SharedPreferences mPrefs; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); facebook = new Facebook(APP_ID); mAsyncRunner = new AsyncFacebookRunner(facebook);
5. I created a simple interface which contains button to login, post to wall, show access tokens and logout for testing purpose.
Login to Facebook Account
I used a button to login into facebook account. In your activity write a click event for Login button click. Inside click event declare a function named loginToFacebook();
Login button click event
btnFbLogin.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { loginToFacebook(); } });
and function body for loginToFacebook() function is:
public void loginToFacebook() { mPrefs = getPreferences(MODE_PRIVATE); String access_token = mPrefs.getString("access_token", null); long expires = mPrefs.getLong("access_expires", 0); if (access_token != null) { facebook.setAccessToken(access_token); } if (expires != 0) { facebook.setAccessExpires(expires); } if (!facebook.isSessionValid()) { facebook.authorize(this, new String[] { "email", "publish_stream" }, new DialogListener() { @Override public void onCancel() { // Function to handle cancel event } @Override public void onComplete(Bundle values) { // Function to handle complete event // Edit Preferences and update facebook acess_token SharedPreferences.Editor editor = mPrefs.edit(); editor.putString("access_token", facebook.getAccessToken()); editor.putLong("access_expires", facebook.getAccessExpires()); editor.commit(); } @Override public void onError(DialogError error) { // Function to handle error } @Override public void onFacebookError(FacebookError fberror) { // Function to handle Facebook errors } }); } }
Posting Message to Facebook Wall
write a click event for post to wall button and inside click event write a function named postToWall()
btnPostToWall.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { postToWall(); } });
and function body for postToWall() function is:
public void postToWall() { // post on user's wall. facebook.dialog(this, "feed", new DialogListener() { @Override public void onFacebookError(FacebookError e) { } @Override public void onError(DialogError e) { } @Override public void onComplete(Bundle values) { } @Override public void onCancel() { } }); }
Getting Profile Information from Facebook
To get profile information we need to make an api request to facebook graph API. Following is a function that will make an api request to facebook profile graph api and will get profile information from facebook.
getProfileInformation()
public void getProfileInformation() { mAsyncRunner.request("me", new RequestListener() { @Override public void onComplete(String response, Object state) { Log.d("Profile", response); String json = response; try { JSONObject profile = new JSONObject(json); // getting name of the user String name = profile.getString("name"); // getting email of the user String email = profile.getString("email"); runOnUiThread(new Runnable() { @Override public void run() { Toast.makeText(getApplicationContext(), "Name: " + name + "\nEmail: " + email, Toast.LENGTH_LONG).show(); } }); } catch (JSONException e) { e.printStackTrace(); } } @Override public void onIOException(IOException e, Object state) { } @Override public void onFileNotFoundException(FileNotFoundException e, Object state) { } @Override public void onMalformedURLException(MalformedURLException e, Object state) { } @Override public void onFacebookError(FacebookError e, Object state) { } }); }
The above function will get json data from facebook. You need to parse the json in order to get individual profile data. If you are not aware of json parsing look at this article. Android JSON Parsing Tutorial.
The sample profile json from facebook will be like this
{ "id": "1464730016", "name": "Ravi Tamada", "first_name": "Ravi", "last_name": "Tamada", "link": "https://www.facebook.com/ravi8x", "username": "ravi8x", "birthday": "12/22/1988", "hometown": { "id": "112158005464147", "name": "Baruva" }, "location": { "id": "102186159822587", "name": "Chennai, Tamil Nadu" }, "bio": "Author: www.androidhive.info\r\nCo-author: www.9lessons.info", "work": [ { "employer": { "id": "179366562092719", "name": "ByteAlly" }, "location": { "id": "102186159822587", "name": "Chennai, Tamil Nadu" }, "position": { "id": "124917314217511", "name": "Product Head" } ] } ], "favorite_athletes": [ { "id": "18620649907", "name": "Virat Kohli" } ], "education": [ { "school": { "id": "131587206873093", "name": "Raghu Engineering College (REC)" }, "degree": { "id": "140065339390579", "name": "B.Tech" }, "year": { "id": "142963519060927", "name": "2010" }, "type": "Graduate School", "classes": [ { "id": "192259410803415", "name": "2010", "with": [ { "id": "584960408", "name": "Santosh Patnaik" } ], "from": { "id": "584960408", "name": "Santosh Patnaik" } } ] } ], "gender": "male", "relationship_status": "Single", "website": "www.androidhive.info\nwww.9lessons.info\nwww.twitter.com/ravitamada\nwww.about.me/rv", "timezone": 5.5, "locale": "en_US", "languages": [ { "id": "106059522759137", "name": "English" }, { "id": "107617475934611", "name": "Telugu" }, { "id": "112969428713061", "name": "Hindi" }, { "id": "343306413260", "name": "Tamil" } ], "verified": true, "updated_time": "2012-03-02T17:04:18+0000" }
Extending facebook Permissions
If you want user’s other information like checkins, friends list etc., you need to extend facebook permissions while logging in user. Check list of facebook permissions
facebook.authorize(this, new String[] { "email", "publish_checkins", "publish_stream" }, new DialogListener() { @Override public void onComplete(Bundle values) {} @Override public void onFacebookError(FacebookError error) {} @Override public void onError(DialogError e) {} @Override public void onCancel() {} } );
Getting Access Token
Sometimes you might needed users access token for future purpose usage. Following code will give you currently logged in user access token.
String access_token = facebook.getAccessToken();
Logout from your app
When user want to stop using facebook for your app, you can provide logout method to clear app state and invalidate access token. So further you can’t make request to facebook from your app.
logoutFromFacebook();
public void logoutFromFacebook() { mAsyncRunner.logout(this, new RequestListener() { @Override public void onComplete(String response, Object state) { Log.d("Logout from Facebook", response); if (Boolean.parseBoolean(response) == true) { // User successfully Logged out } } @Override public void onIOException(IOException e, Object state) { } @Override public void onFileNotFoundException(FileNotFoundException e, Object state) { } @Override public void onMalformedURLException(MalformedURLException e, Object state) { } @Override public void onFacebookError(FacebookError e, Object state) { } }); }

hi! this is the best tutorial, but i have a problem! I could do the first login with my facebook account, but, now, on the others login i receive an error from facebook page on the app: “Invalid android_key parameter. The key Vp1b———G4TI does not match any allowed key. Configure your app key hashes at http://developers.facebook……/apps/139—– “. I don’t understand this error, because the key cited is not my hash key and why the first login went well?? i think the app is configured well!

Can Use Strict Mode Thread policy… Refer: http://stackoverflow.com/questions/8258725/strict-mode-in-android-2-2
Download openSSL->Install it->it would usually install in C:OpenSSL
then open cmd and type
cd../../Program Files (enter)
java (enter)
dir (enter)
cd jdk1.6.0_17 (varies with jdk versions)
to check jdk version go to C:/program files/java/jdk_version
cd bin (enter)
keytool -exportcert -alias androiddebugkey -keystore C:UsersShalini.androiddebug.keystore | “C:OpenSSLbinopenssl sha1 -binary | “C:OpenSSLbinopenssl base64 (enter)
