Facebook与Android应用程序错误集成

Question

我正在尝试将 Facebook **集成到我的Android应用中。我想在** facebook 上实现**喜欢和分享**设施。但我收到了错误。

请帮我解决这个问题。

此外，我想知道在Facebook上创建新应用程序的过程。

我正在使用 GitHub 中的代码。我的代码是 -

public class MyGreatActivity extends Activity {

    Facebook facebook = new Facebook("333778590046892");

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        facebook.authorize(this, new String[] { "offline_access", "publish_stream", "raj21kadam@gmail.com" },
new DialogListener() {
            @Override
            public void onComplete(Bundle values) {
             String token=facebook.getAccessToken();  //get access token
//             Toast.makeText(this, "token", Toast.LENGTH_LONG).
                save(token);
            }

            @Override
            public void onFacebookError(FacebookError error) {}

            @Override
            public void onError(DialogError e) {}

            @Override
            public void onCancel() {}
        });
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        facebook.authorizeCallback(requestCode, resultCode, data);
    }

    private void save(String token){
     Toast.makeText(this, "token"+token, Toast.LENGTH_LONG).show();
     SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
     prefs.edit().putString("Token", token).commit();
     }
}

运行上面的代码时出现以下错误 -

Dialog Errorcom.facebook.android.DialogError: The connection to the server was unsuccessful.

试试这个Single Sign On (SSO) Using Android Native Client For Facebook 。 粘贴这个

facebook.authorize(this, new DialogListener() {

@Override
        public void onComplete(Bundle values) {
         String token=facebook.getAccessToken();  //get access token
//             Toast.makeText(this, "token", Toast.LENGTH_LONG).
            save(token);
        }

        public void onFacebookError(FacebookError error) {}

        @Override
        public void onError(DialogError e) {}

        @Override
        public void onCancel() {}
    });
}

而不是

facebook.authorize(this, new String[] { "offline_access", "publish_stream",   "raj21kadam@gmail.com" },
new DialogListener() {
        @Override
        public void onComplete(Bundle values) {
         String token=facebook.getAccessToken();  //get access token

        }

        @Override
        public void onFacebookError(FacebookError error) {}

        @Override
        public void onError(DialogError e) {}

        @Override
        public void onCancel() {}
    });
}
