Question

我正在使用android-facebook-sdk，我正在尝试请求个人资料信息。但我无法得到回复。我已经使用keytool生成了密钥哈希并将其粘贴到facebook应用程序设置中。此外，我在代码中添加了应用程序ID。问题是我无法获取个人资料信息或任何信息。

 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" },

            new DialogListener() {
                @Override
                public void onComplete(Bundle values) {
                    SharedPreferences.Editor editor = mPrefs.edit();
                    editor.putString("access_token", facebook.getAccessToken());
                    editor.putLong("access_expires",
                            facebook.getAccessExpires());
                    editor.commit();


                }

                @Override
                public void onFacebookError(FacebookError error) {
                }

                @Override
                public void onError(DialogError e) {
                }

                @Override
                public void onCancel() {
                }

            });

        }
    }

    @Override
    protected void onResume() {
        // TODO Auto-generated method stub
        super.onResume();
        facebook.extendAccessTokenIfNeeded(this, null);
    }


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

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


    public void getProfileInformation() {

        mAsyncRunner.request("me", new RequestListener() {

            @Override
            public void onComplete(String response, Object state) {
                Log.d("Profile", response);
                String json = response;

                try {
                    JSONObject profile = new JSONObject(json);
                    // getting name of the user
                    final String name = profile.getString("name");
                    // getting email of the user
                    final String email = profile.getString("email");

                    runOnUiThread(new Runnable() {

                        @Override
                        public void run() {
                            Toast.makeText(getApplicationContext(), "Name: " + name + "\nEmail: " + email, Toast.LENGTH_LONG).show();
                        }

                    });

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

            @Override
            public void onIOException(IOException e, Object state) {
            }

            @Override
            public void onFileNotFoundException(FileNotFoundException e,
                    Object state) {
            }

            @Override
            public void onMalformedURLException(MalformedURLException e,
                    Object state) {
            }

            @Override
            public void onFacebookError(FacebookError e, Object state) {
            }
        });
    }
}

错误表示您没有必需的访问令牌。尝试打印facebook.getaccesstoken()并查看您是否拥有有效令牌。使用此令牌，您可以在浏览器中尝试查看是否获得了个人资料信息
