Question

There is an application in facebook called poll(opinion poll), where you can give a question and some options. After you create the poll, others can start to vote. Can I create the poll in my android app and publish it in facebook? i.e the user will give his facebook login credentials and teh app will create the poll on his behalf. Are there any such API’s?

Answer 1

Yes, it is possible. The relevant documentation is here: https://developers.facebook.com/docs/reference/api/question/

To do this on your android app, you need to add our Facebook SDK for Android to your app. Once you do so, to create a question you just need to do the following

1. Authenticate the user via Facebook to get a valid access token
2. Request the publish_stream and user_questions permissions

Then you just need the following code to create a question and publish it to Facebook:

Bundle params = new Bundle();
params.putString("question", "Cats or dogs?");
JSONObject questions = new JSONObject();
questions.put("Cat");
questions.put("Dog");
params.putString("options", questions.toString())

mAsyncRunner.request("me/questions", params, "POST", new RequestListener() {
    @Override
    public void onComplete(Bundle values) {
        // success
        Log.d("fb", values.toString());
    }
    @Override
    public void onFacebookError(FacebookError e, final Object state) {
        Log.e("Facebook", e.getMessage());
        e.printStackTrace();
    }

    @Override
    public void onFileNotFoundException(FileNotFoundException e, final Object state) {
        Log.e("Facebook", e.getMessage());
        e.printStackTrace();
    }

    @Override
    public void onIOException(IOException e, final Object state) {
        Log.e("Facebook", e.getMessage());
        e.printStackTrace();
    }     

    @Override
    public void onMalformedURLException(MalformedURLException e, final Object state) {
        Log.e("Facebook", e.getMessage());
        e.printStackTrace();
    }
