Android Facebook Integration



Hello Friends,
               This tutorial is about integrating facebook into your android   
               application. 
              
     
               Step 1: Registering Your Facebook Application:
               Go to facebook developer app site and Create the application.
               create new facebook application and fill out all the information 
               needed. And select Native Android App.
               And  note down your facebook App ID.
              
     
           Step 2: Creating Facebook Reference Project :
                         Once you are done with registering your facebook 
           application,    you need to download facebook SDK and create 
           a new library project. This reference project will be used to
           compile your actual project.
                    1. Download facebook android SDK from git repo-
               sitories.


          2. In your Eclipse goto File ⇒ Import ⇒ Existing Projects
              into Workspace and select the facebook project you downloaded
              from git repository.
                                  








       Now, You are ready to run the project  :) .
    
       Screen Shot of my project:











   Code:     
   1. Get Profile Information:
        
          

        /**
  * Get Profile information by making request to Facebook Graph API
  * */
 public void getProfileInformation() {
  mAsyncRunner.request("me", new RequestListener() {
   @Override
   public void onComplete(String response, Object state) {
    Log.d("Profile", response);
    String json = response;
    try {
     // Facebook Profile JSON data
     JSONObject profile = new JSONObject(json);
     
     // getting name of the user
     final String name = profile.getString("name");
     
     // getting email of the user
     final String email = profile.getString("email");
     
     // getting user name of the user
     username = profile.getString("username");
     
     runOnUiThread(new Runnable() {

      @Override
      public void run() {
       Toast.makeText(getApplicationContext(), "Name: " + name + "\nEmail: " + email +"\nUserName : "+username, 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) {
   }
  });
 }
 
2.Get All my Facebook Friends :
 
 
 mAsyncRunner.request(username+"/picture", new RequestListener() {
   @Override
   public void onComplete(String response, Object state) {
    Log.d("Profile", response);
    String json = response;
    try {
     // Facebook Profile JSON data
     JSONObject profile = new JSONObject(json);
     JSONArray arrayFriend = profile.getJSONArray("data");
     Log.d("Profile======", arrayFriend.toString());
     // getting name of the user
     
     if (arrayFriend != null) {
               for (int i = 0; i < arrayFriend.length(); i++) {
                   String name = arrayFriend.getJSONObject(i).getString("name");

                   String id = arrayFriend.getJSONObject(i).getString("id");

                   Log.i(name,id);
                   
               }
           } 
     final String name = profile.getString("name");
     
     // getting email of the user
     final 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();
   }
 
  3. Getting my facebook profile Picture
 
  
    Code:
 
    ImageView user_picture;
    user_picture=(ImageView)findViewById(R.id.imageView);
    URL url;
    try {
 url = new URL("http://graph.facebook.com/"+username+"/picture?type=large");
        Bitmap bmp = BitmapFactory.decodeStream(url.openConnection().getInputStream());
 user_picture.setImageBitmap(bmp);
 } catch (MalformedURLException e) {
   // TODO Auto-generated catch block
     e.printStackTrace();

 }
