Android - Facebook登录首次导致onResume错误

Question

我可以成功连接到Facebook并获得好友列表.所有连接都没问题.但是当我删除Facebook的数据(通过设置 - >应用程序)和我的应用程序时,会出现登录问题.[SDK 3.5]

1. 启动我的应用
2. 建立Facebook连接
3. Facebook要求输入用户名和密码,输入它们
4. 等一下
5. 它显示请求基本用户信息和错误的权限屏幕:"您的应用程序意外停止工作.请再试一次(强制关闭)"

当我单击强制关闭时,会再次突然发生同样的错误(同时权限屏幕仍然落后).如果我足够快,我点击强制关闭然后允许权限,一切正常,我可以看到我的朋友.所以这个FORCE CLOSE错误意味着什么都没有？在日志中,有3-4个相同的致命异常消息,因为每次单击FORCE CLOSE时,都会再次出现错误.当我在手机上尝试应用程序时出现此错误(SE Xperia Arc S,2.3.3).但是当我尝试使用Emulators时,错误不会发生.它没有问题.(仿真器是2.3.3和4.2)

第一次连接后,我可以毫无错误地找到我的朋友.它只是在我第一次连接Facebook并且它询问我的用户名和密码(然后点击登录)之后才发生

@Override
  public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    uiHelper = new UiLifecycleHelper(this, callback);
    uiHelper.onCreate(savedInstanceState);

    setContentView(R.layout.activity_fb_findfriends);
    LinearLayout v = (LinearLayout) findViewById(R.id.fb_app_users);
    openSession(v);

  }

public void openSession(View v){
        // start Facebook Login
        Session.openActiveSession(this, true, callback);

    }

@Override
  protected void onResume() {
      super.onResume();
      uiHelper.onResume();
      Log.e("ONRESUME", "Onresume çal??t?");
  }

private void requestMyAppFacebookFriends(Session session) {
        Request friendsRequest = createRequest(session);
        friendsRequest.setCallback(new Request.Callback() {

            @Override
            public void onCompleted(Response response) {

                List<GraphUser> friends = getResults(response);
                //Display Friends
            }
        });
    friendsRequest.executeAsync();
}

此外,我无法理解日志输出中的null.

UPDATE!我找到了发生错误的行.它位于com.facebook.AuthorizationClient.java第135行内

void startOrContinueAuth(AuthorizationRequest request) {
        if (appEventsLogger == null || appEventsLogger.getApplicationId() != request.getApplicationId()) {
            Log.e("HATA!", "BOOM");
            appEventsLogger = AppEventsLogger.newLogger(context, request.getApplicationId());
        }

这个startOrContinueAuth方法在com.Facebook.LoginActivity中触发

@Override
public void onResume() {
    super.onResume();

    // If the calling package is null, this generally means that the callee was started
    // with a launchMode of singleInstance. Unfortunately, Android does not allow a result
    // to be set when the callee is a singleInstance, so we log an error and return.
    if (callingPackage == null) {
        Log.e(TAG, "Aheyy"+NULL_CALLING_PKG_ERROR_MSG);
        finish();
        return;
    }

    authorizationClient.startOrContinueAuth(request);
}
        if (getInProgress()) {
            continueAuth();
        } else {
            authorize(request);
        }
    }

更新2!

• 我很困惑.我将我的应用程序简化为非常基本的openActiveSession()方法.崩溃
• 我试过Facebook,FriendPicker的示例应用程序,它也崩溃了相同的日志错误输出.
• 尝试在模拟器上,它工作,但当我在授权屏幕显示(取消 - 允许)时旋转屏幕,同样的错误发生(无法onResume等等等等......)在Facebook的示例应用程序上获得相同的错误很奇怪

我不认为这是您的应用程序的问题。人们已经报告了这个错误，我刚刚在这里回答了类似的问题。基本上，Facebook 昨天发布了新版本的 SDK，修复了 AuthorizationClient 中的 onResume NPE 崩溃问题。查看升级是否可以解决您的问题。
