Adding content to Facebook feed dialog from Facebook SDK for Android

Question

In my android app, I want users to "share" my app in their wall, so I want them to post a predefined content status on their wall.

How can I customize the wall status? (I want to add my app icon and some flare text).

Answer 1

Download the Facebook SDK and import it in your project. Then use the following code to Authorize:

    public void sendtoFacebook(){
        facebookClient = new Facebook("<Your_APP_ID");
        facebookClient.authorize(<Current_class>.this, new AuthorizeListener());
    }

Now you have to add the following methodes:

class AuthorizeListener implements DialogListener {
    public void onComplete(Bundle values) {
        Bundle parameters = new Bundle();
            parameters.putString("message", "<Message_you_want_to_send>");// the message to post to the wall
            facebookClient.dialog(<Current_class>.this, "stream.publish", parameters, this);// "stream.publish" is an API call
    }
    @Override
    public void onFacebookError(FacebookError e) {
    }
    @Override
    public void onError(DialogError e) {
    }
    @Override
    public void onCancel() {
    }
}

Your Application name and Icon will automatically be added :)

After learning the Facebook API, I came across this page

so now I know all the options for the bundle parameters. Thanks everyone for your help!

You can also do that without the SDK, just via Share URL:

public void shareOnFacebook(View v) {

    Uri uri = Uri.parse("http://m.facebook.com/sharer.php?u=http://yourdomain/page.html&t=YourMessage");
    Intent intent = new Intent(Intent.ACTION_VIEW, uri);
    startActivity(intent);
}

You just need to put a content page / html somewhere on your server, under the url your provided to the sharer.

If you want that a certain image appears in the shared message, put this in the meta tag of your html page on the server that you're sharing:

<link rel="image_src" type="image/jpeg" href="http://yourdomain.com/promo/image.png" />

This is how I am making a bundle to set content via a facebook dialog using the Facebook SDK

Bundle parameters = new Bundle();
        parameters.putString("app_id", "xxxxxxx");
        parameters.putString("link", "https://play.google.com/store/apps/details?id=myappistasty");
        parameters.putString("name", "This is the name of the link set in app.");
        parameters.putString("caption", "This is Text that is specified in bt the aoo");
        parameters.putString("picture", "www.urltoimage.com);
facebook.dialog(MainActivity.this, "feed", parameters, new DialogListener() {
etc...

http://developers.facebook.com/docs/reference/dialogs/feed/ this is the link that explained all to me, although none of it is in java the table gives you a good idea.
