How can I post text only to my Facebook wall in Android?

Question

Currently, I am using the following code:

Bundle params = new Bundle();
//params.putString("message", "I want to post this text only.");
params.putString("name", "Facebook SDK for Android");
params.putString("caption", "Build great social apps and get more installs.");
params.putString("description", "Description");
params.putString("link", "https://developers.facebook.com/android");
params.putString("picture", "https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png");

WebDialog feedDialog = (
    new WebDialog.FeedDialogBuilder(getActivity(),
        Session.getActiveSession(),
        params))
    .setOnCompleteListener(new OnCompleteListener() {

However, I can't post message only, because the bundle must include "link".

Here is the complete solution.Please try this out,i am using this code and works completely fine. if you are not logged in( if you are using first time) you will direct to login screen (else) and access token got stored in local data.after that you are allowed to share text to facebook wall.

if (facebook.getAccessToken() != null) {

            postOnWall("msg to share");

        } else {
            loginToFacebook();

            }

public void postOnWall(String msg) {
    Log.d("Tests", "Testing graph API wall post");
    try {
        String response = facebook.request("me");
        Bundle parameters = new Bundle();

        parameters.putString("message", msg);
        parameters.putString("description", "test test test");
        // parameters.putByteArray("message", msg);
        response = facebook.request("me/feed", parameters, "POST");
        Log.d("Tests", "got response: " + response);
        if (response == null || response.equals("")
                || response.equals("false")) {
            Log.v("Error", "Blank response");

            Toast.makeText(getApplicationContext(), "FacebookError",Toast.LENGTH_SHORT).show();

        }
    } catch (Exception e) {
        e.printStackTrace();

    }
}

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);

        Log.d("FB Sessions", "" + facebook.isSessionValid());
    }

    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();
                        Toast.makeText(sms_by_id.this,
                                "Successfully Login", Toast.LENGTH_LONG)
                                .show();
                        pwindo.dismiss();

                        // Making Login button invisible

                    }

                    @Override
                    public void onError(DialogError error) {
                        // Function to handle error

                    }

                    @Override
                    public void onFacebookError(FacebookError fberror) {
                        // Function to handle Facebook errors
                        pwindo.dismiss();
                        Toast.makeText(sms_by_id.this, "Facebook Error",
                                Toast.LENGTH_LONG).show();
                    }

                });
    }
}

Answer 2

because the bundle must include "link".

This statement is incorrect. In the params, just include the message property that's it! Don't provide link/picture/caption/description etc. since all these are related to the link only. So, just use the message param and it be be posted as the text only.

Answer 3

All you need to do is change the Bundle as motioned by user1632209

        Bundle parameters = new Bundle();

        params.putString("message", msg);
        params.putString("description", "test test test");

try this
