Post on Facebook wall without showing dialog on android

I found out what the problem was. I was not asking the right permissions and the graph path was also wrong. The right method is :

public static void PublishToFeedInBackground()
{

final Bundle _postParameter = new Bundle();
 _postParameter.putString("name", name);
 _postParameter.putString("link", link);
 _postParameter.putString("picture", link_to_image);
 _postParameter.putString("caption", caption);
 _postParameter.putString("description", description);

     final List<String> PERMISSIONS = Arrays.asList("publish_stream");

 if (Session.getActiveSession() != null)
 {
       NewPermissionsRequest reauthRequest = new Session.NewPermissionsRequest(this.GetContext(), PERMISSIONS);
        Session.getActiveSession().requestNewPublishPermissions(reauthRequest);
 }

this.runOnUiThread(new Runnable()
{
    @Override
    public void run() 
    {
        Request request = new Request(Session.getActiveSession(), "feed", _postParameter, HttpMethod.POST);

        RequestAsyncTask task = new RequestAsyncTask(request);
        task.execute();
    }
});
}

Android Facebook SDK : post message without showing facebook page

Its not possible.

You must have to login into facebook accountto post the message on Facebook.

Your requirement is only possible if you stored the facebook id and password staticaly in to the application.

Well but there is one alternate of it. If you use facebook sdk to implement the post message on Facebook then it may help you. With using that you can only able to get the facebook login screen once. If user has registered with that login id and password then it will never come again and simple send varification toast message that the message is posted on facebook.

For the above example refer this examples.

1. Example 1
2. Example 2
3. Demo Example
4. Example 4

Hope it will help you. If not then let me know.

Enjoy. :)

Updated

For to post the static message on facebook, do like below after integrating the Facebook sdk in to the project:

System.out.println("Message is: "+postMessage); // My static post message

                        facebook.authorize(MainActivityPage.this, new String[]{ "user_photos,publish_checkins,publish_actions,publish_stream"},new DialogListener() {                     
                            @Override                     
                            public void onComplete(Bundle values) {   

                                Bundle params = new Bundle();              
                                params.putString(Facebook.TOKEN, facebook.getAccessToken());              
                                params.putString("message", postMessage);               

                                AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);              
                                mAsyncRunner.request("me/feed", params, "POST", new SampleUploadListener(),null);

                                Toast.makeText(getApplicationContext(), "Message Posted on Facebook.", Toast.LENGTH_SHORT).show();
                            }                      
                            @Override                     
                            public void onFacebookError(FacebookError error) {}                      
                            @Override                     
                            public void onError(DialogError e) {}                      
                            @Override                     
                            public void onCancel() {}                 
                        });

post a message to facebook wall from android studio project

post some predefined text

That part is impossible and not allowed, because:

Don't prefill captions, comments, messages, or the user message
parameter of posts with content a person didn’t create, even if the
person can edit or remove the content before sharing.

Source: https://developers.facebook.com/policy/

Obviously, you will never get the required permission (publish_actions) approved for posting predefined text.
