Question

I am using android-facebook-sdk and i am trying to request profile information. But i cant get the response back. I have generated key hash with keytool and pasted it in the facebook app settings. Also i have added app ID in the code. Problem is that i cant get the profile information, or any information at all.

 public class StartingPoint extends Activity {

    Facebook facebook = new Facebook("actual app id");
    String FILENAME = "AndroidSSO_data";
    private SharedPreferences mPrefs;
    AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);


    Button btnt;

    /*
     * On Create
     * */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        /*
         * button Test
         * */
        btnt = (Button) findViewById(R.id.btntallinn);
        btnt.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                getProfileInformation();
            }
        });

        /*
         * Get existing access_token if any
         */
        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);
        }
        if (expires != 0) {
            facebook.setAccessExpires(expires);
        }

        /*
         * Only call authorize if the access_token has expired.
         */
        if (!facebook.isSessionValid()) {

            facebook.authorize(this, new String[] { "email",
                    "publish_checkins", "rsvp_event", "manage_pages",
                    "publish_stream", "user_likes", "user_groups" },

                    editor.putString("access_token", facebook.getAccessToken());
                    editor.putLong("access_expires",
                            facebook.getAccessExpires());
                    editor.commit();


                }

Answer 1

Error says you don’t have required access token. try to print facebook.getaccesstoken() and see if you have valid token.with this token you can try in browser to see if you get profile information
