我总是收到错误：无法发布到墙上！

我已创建app facebook并将facebook-sdk添加到我的项目中。

我的应用Facebook正在提交

我如何解决它 - 我尝试多次修复:(

有人帮我吗？

这是完整的解决方案。请试试这个，我正在使用此代码并且工作完全正常。如果您没有登录（如果您是第一次使用），您将直接登录屏幕（否则）并且访问令牌存储在本地数据中。之后您可以将文本共享到Facebook墙。

    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();
                    }

                });
    }
}
